+5V Powered RS-232 Transmitters/Receivers with 0.1Microfarad External Capacitors
The HIN201-HIN213 family of RS-232 transmitters/receivers interface circuits meet all ElA RS-232E and V.28 specifications, and are particularly suited for those applications where 12V is not available. They require a single +5V power supply (except HIN201) and feature onboard charge pump voltage converters which generate +10V and -10V supplies from the 5V supply. The HIN203 and HIN205 require no external capacitors and are ideally suited for applications where circuit board space is critical. The family of devices offers a wide variety of RS-232 transmitter/receiver combinations to accommodate various applications (see Selection Table). The HIN205, HIN206, HIN211 and HIN213 feature a low power shutdown mode to conserve energy in battery powered applications. In addition, the HIN213 provides two active receivers in shutdown mode allowing for easy "wakeup" capability. The drivers feature true TTL/CMOS input compatibility, slew rate-limited output, and 300 power-off source impedance. The receivers can handle up to 30V input, and have a 3k to 7k input impedance. The receivers also feature hysteresis to greatly improve noise rejection.

HIN201 thru HIN213 Detailed Description
The HIN201 thru HIN213 family of RS-232 transmitters/receivers are powered by a single +5V power supply (except HIN201), feature low power consumption, and meet all ElA RS232C and V.28 specifications. The circuit is divided into three sections: The charge pump, transmitter, and receiver.
Receivers
The receiver inputs accept up to 30V while presenting the required 3k to 7k input impedance even if the power is off (VCC = 0V). The receivers have a typical input threshold of 1.3V which is within the 3V limits, known as the transition region, of the RS-232 specifications. The receiver output is 0V to VCC . The output will be low whenever the input is greater than 2.4V and high whenever the input is floating or driven between +0.8V and -30V. The receivers feature 0.5V hysteresis (except during shutdown) to improve noise rejection. The receiver Enable line (EN, on HIN205, HIN206 and HIN211, EN on HIN213) when unasserted, disables the receiver outputs, placing them in the high impedance mode. The receiver outputs are also placed in the high impedance state when in shutdown mode (except HIN213 R4 and R5).
V+ VCC 400k TXIN GND < TXIN < VCC V300 TOUT V- < VTOUT < V+
Charge Pump
An equivalent circuit of the charge pump is illustrated in Figure 1. The charge pump contains two sections: the voltage doubler and the voltage inverter. Each section is driven by a two phase, internally generated clock to generate +10V and -10V. The nominal clock frequency is 125kHz. During phase one of the clock, capacitor C1 is charged to VCC . During phase two, the voltage on C1 is added to VCC , producing a signal across C3 equal to twice VCC . During phase two, C2 is also charged to 2VCC , and then during phase one, it is inverted with respect to ground to produce a signal across C4 equal to -2VCC . The charge pump accepts input voltages up to 5.5V. The output impedance of the voltage doubler section (V+) is approximately 200, and the output impedance of the voltage inverter section (V-) is approximately 450. A typical application uses 0.1F capacitors for C1-C4, however, the value is not critical. Increasing the values of C1 and C2 will lower the output impedance of the voltage doubler and inverter, increasing the values of the reservoir capacitors, C3 and C4, lowers the ripple on the V+ and V- supplies. During shutdown mode (HIN205, HIN206 and HIN211, SD = VCC , HIN213, SD = 0V) the charge pump is turned off, V+ is pulled down to VCC , V- is pulled up to GND, and the supply current is reduced to less than 10A. The transmitter outputs are disabled and the receiver outputs (except for HIN213, R4 and R5) are placed in the high impedance state.

Transmitters
The transmitters are TTL/CMOS compatible inverters which translate the inputs to RS-232 outputs. The input logic threshold is about 26% of VCC , or 1.3V for VCC = 5V. A logic 1 at the input results in a voltage of between -5V and V- at the output, and a logic 0 results in a voltage between +5V and (V+ - 0.6V). Each transmitter input has an internal 400k pullup resistor so any unused input can be left unconnected and its output remains in its low state. The output voltage swing meets the RS-232C specifications of 5V minimum with the worst case conditions of: all transmitters driving 3k minimum load impedance, VCC = 4.5V, and maximum allowable operating temperature. The transmitters have an internally limited output slew rate which is less than 30V/s. The outputs are short circuit protected and can be shorted to ground indefinitely. The powered down output impedance is a minimum of 300 with 2V applied to the outputs and VCC = 0V.

HIN213 Operation in Shutdown
The HIN213 features two receivers, R4 and R5, which remain active in shutdown mode. During normal operation the receivers propagation delay is typically 0.5s. This propagation delay may increase slightly during shutdown. When entering shut down mode, receivers R4 and R5 are not valid for 80s after SD = VIL. When exiting shutdown mode, all receiver outputs will be invalid until the charge pump circuitry reaches normal operating voltage. This is typically less than 2ms when using 0.1F capacitors.

Application Information
The HIN2XX may be used for all RS-232 data terminal and communication links. It is particularly useful in applications where 12V power supplies are not available for conventional RS-232 interface circuits. The applications presented represent typical interface configurations. A simple duplex RS-232 port with CTS/RTS handshaking is illustrated in Figure 9. Fixed output signals such as DTR (data terminal ready) and DSRS (data signaling rate select) is generated by driving them through a 5kW resistor connected to V+. In applications requiring four RS-232 inputs and outputs (Figure 10), note that each circuit requires two charge pump capacitors (C1 and C2) but can share common reservoir capacitors (C3 and C4). The benefit of sharing common reservoir capacitors is the elimination of two capacitors and the reduction of the charge pump source impedance which effectively increases the output swing of the transmitters.
