Low-Voltage, CMOS Analog Multiplexers/Switches with Enable Inputs and Address Latching
_______________General Description
The MAX4530/MAX4531/MAX4532 are low-voltage, CMOS analog ICs configured as an 8-channel multiplexer (mux) (MAX4530), two 4-channel muxes (MAX4531), and three single-pole/double-throw switches (MAX4532). These devices are pin compatible with the industry-standard 74HC4351/74HC4352/ 74HC4353. All devices have two complementary switch-enable inputs and address latching. The MAX4530/MAX4531/MAX4532 operate from a single supply of +2V to +12V, or from dual supplies of 2V to 6V. On-resistance (150 max) is matched between switches to 8 max. Each switch can handle rail-to-rail analog signals. Off-leakage current is only 1nA at TA = +25C and 50nA at TA = +85C. All digital inputs have 0.8V and 2.4V logic thresholds, ensuring both TTL- and CMOS-logic compatibility when using 5V or a single +5V supply.

Stresses beyond those listed under "Absolute Maximum Ratings" may cause permanent damage to the device.

Note 2: The algebraic convention, where the most negative value is a minimum and the most positive value a maximum, is used in this data sheet. Note 3: Guaranteed by design. Note 4: RON = RON(max) - RON(min). Note 5: Flatness is defined as the difference between the maximum and minimum value of on-resistance as measured over the specified analog signal ranges, i.e., VNO = 3V to 0V and 0V to -3V. Note 6: Leakage parameters are 100% tested at maximum rated hot operating temperature, and guaranteed by correlation at TA = +25C. Note 7: Worst-case isolation is on channel 4 because of its proximity to the COM pin. Off isolation = 20log VCOM / VNO, VCOM = output, VNO = input to off switch. Note 8: Leakage testing at single supply is guaranteed by correlation testing with dual supplies.

Low-Voltage, CMOS Analog Multiplexers/Switches with Enable Inputs and Address Latching
__________Applications Information
Power-Supply Considerations
Overview The MAX4530/MAX4531/MAX4532 construction is typical of most CMOS analog switches. They have three supply pins: V+, V-, and GND. V+ and V- drive the internal CMOS switches and set the limits of the analog voltage on any switch. Reverse ESD-protection diodes are internally connected between each analog-signal pin and both V+ and V-. One of these diodes conducts if any analog signal exceeds V+ or V-. During normal operation, these and other reverse-biased ESD diodes leak, forming the only current drawn from V+ or V-. Virtually all of the analog leakage current comes from the ESD diodes. Although the ESD diodes on a given signal pin are identical and therefore fairly well balanced, they are reverse biased differently. Each is biased by either V+ or V- and the analog signal. This means their leakages vary as the signal varies. The difference in the two diode leakages to the V+ and Vpins constitutes the analog-signal-path leakage current. All analog leakage current flows between each pin and one of the supply terminals, not to the other switch terminal. For this reason, both sides of a given switch can show leakage currents of either the same or opposite polarity. The analog-signal paths and GND are not connected. V+ and GND power the internal logic and logic-level translators, and set both the input and output logic limits. The logic-level translators convert the logic levels into switched V+ and V- signals to drive the analog signals' gates. This drive signal is the only connection between the logic supplies and signals and the analog supplies. V+ and V- have ESD-protection diodes to GND.
The logic-level thresholds are TTL/CMOS compatible when V+ = +5V. As V+ rises, the threshold increases slightly, so when V+ reaches +12V, the threshold is about 3.1V--above the TTL guaranteed, high-level minimum of 2.8V, but still compatible with CMOS outputs.
MAX4530/MAX4531/MAX4532
Bipolar Supplies The MAX4530/MAX4531/MAX4532 operate with bipolar supplies between 2.0V and 6V. The V+ and V- supplies need not be symmetrical, but their sum cannot exceed the +13V absolute maximum rating. Single Supply The MAX4530/MAX4531/MAX4532 operate from a single supply between +2V and +12V when V- is connected to GND. All of the bipolar precautions must be observed. At room temperature, they actually work with a single supply at, near, or below +1.7V, although as supply voltage decreases, switch on-resistance and switching times become very high.
High-Frequency Performance
In 50systems, signal response is reasonably flat up to 50MHz (see Typical Operating Characteristics). Above 20MHz, the on response has several minor peaks that are highly layout dependent. The problem is not in turning the switch on, but in turning it off. The off-state switch acts like a capacitor and passes higher frequencies with less attenuation. At 10MHz, off isolation is about -65dB in 50systems, becoming worse (approximately 20dB per decade) as frequency increases. Higher circuit impedances also make off isolation worse. Adjacent channel attenuation is about 3dB above that of a bare IC socket, and is due entirely to capacitive coupling.

MEASUREMENTS ARE STANDARDIZED AGAINST SHORT AT SOCKET TERMINALS. OFF ISOLATION IS MEASURED BETWEEN COM_ AND OFF NO_ TERMINAL ON EACH SWITCH. ON LOSS IS MEASURED BETWEEN COM_ AND ON TERMINAL ON EACH SWITCH. CROSSTALK (MAX4531/MAX4532 IS MEASURED FROM ONE CHANNEL (A, B, C) TO ALL OTHER CHANNELS. SIGNAL DIRECTION THROUGH SWITCH IS REVERSED; WORST VALUES ARE RECORDED.
