| STP16C596 16-BIT CONSTANT CURRENT LED SINK DRIVER s s s s s s s s 16 CONSTANT CURRENT OUTPUT CHANNELS ADJUSTABLE OUTPUT CURRENT THROUGH EXTERNAL RESISTOR SERIAL DATA IN/PARALLEL DATA OUT SERIAL OUT CHANGE STATE ON THE FAILING EDGES OF CLOCK OUTPUT CURRENT: 15-120 mA 25 MHz CLOCK FREQ. AVAILABLE IN HIGH THERMAL TSSOP EXPOSED PAD EFFICIENCY PACKAGE DIP-24 SO-24 DESCRIPTION The STP16C596 is a monolithic, medium-voltage, low current power 16-bit shift register designed for LED panel displays. The STP16C596 contains a 16-bit serial-in, parallel-out shift register that feeds a 16-bitD-type storage register. In the output stage, sixteen regulated current sources are designed to provide 15-120mA constant current to drive the LEDs. The serial output change state on the failing edges of clock, this special feature will provide an improved performance of the application when the clock signal is skewed because the daisy chain is too long. Table 1: Order Codes Part Number STP16C596B1R STP16C596M STP16C596MTR STP16C596TTR STP16C596XTTR Package TSSOP24 TSSOP24 (exposed pad) Through an external resistor, users may adjust the STP16C596 output current, controlling in this way the light intensity of LEDs. The STP16C596 guarantees a 16V output driving capability, allowing users to connect more LEDs in series. The high clock frequency, 25 MHz, also satisfies the system demand for high volume data transmission. Compared with a standard TSSOP package, the TSSOP exposed pad increases heat dissipation capability by a 2.5 factor.

Figure 7: Timing Diagram Note: The latches circuit holds data when the LE terminal is Low. When LE terminal is at High level, latch circuit doesn't hold the data it passes from the input to the output. When OE terminal is at Low level, output terminals OUT0 to OUT15 respond to the data, either ON or OFF. When OE terminal is at High level, it switches off all the data on the output terminal. 7/18 STP16C596 Figure 8: Clock, Serial-in, Serial-out Figure 9: Clock, Serial-in, Latch, Enable, Outputs 8/18 STP16C596 Figure 10: Outputs TEST CIRCUIT Figure 11: DC Characteristic Figure 12: AC Characteristic 9/18 STP16C596 Figure 13: Output Current-R EXT Resistor Figure 14: Power Dissipation vs Temperature Package 10/18 STP16C596 Plastic DIP-24 (0.25) MECHANICAL DATA mm.
