SL74HC75

SL74HC75 Dual 2-Bit Transparent Latch High-Performance Silicon-Gate CMOS The SL74HC75 is identical in pinout to the LS/ALS75. The device inputs are compatible with standard CMOS outputs; with pullup resistors, they are compatible with LS/ALSTTL outputs. This device consists of two independent 2-bit transparent latches and can be used as temporary storage for binary information between processing units and input/output or indicator units. Each latch stores the input data while Latch Enable is at a logic low. The outputs follow the data inputs when Latch Enable is at a logic high. • Outputs Directly Interface to CMOS, NMOS, and TTL • Operating Voltage Range: 2.0 to 6.0 V • Low Input Current: 1.0 µA • High Noise Immunity Characteristic of CMOS Devices ORDERING INFORMATION SL74HC75N Plastic SL74HC75D SOIC TA = -55° to 125° C for all packages PIN ASSIGNMENT LOGIC DIAGRAM FUNCTION TABLE PIN 5=VCC PIN 12 = GND D L H X Inputs Latch Enable H H L Outputs Q L H Q0 Q H L Q0 X = Don’t Care Q0 = latched data SLS System Logic Semiconductor SL74HC75 MAXIMUM RATINGS * Symbol VCC VIN VOUT IIN IOUT ICC PD T stg TL * Parameter DC Supply Voltage (Referenced to GND) DC Input Voltage (Referenced to GND) DC Output Voltage (Referenced to GND) DC Input Current, per Pin DC Output Current, per Pin DC Supply Current, VCC and GND Pins Power Dissipation in Still Air, Plastic DIP+ SOIC Package+ Storage Temperature Lead Temperature, 1 mm from Case for 10 Seconds (Plastic DIP or SOIC Package) Value -0.5 to +7.0 -1.5 to VCC +1.5 -0.5 to VCC +0.5 ±20 ±25 ±50 750 500 -65 to +150 260 Unit V V V mA mA mA mW °C °C Maximum Ratings are those values beyond which damage to the device may occur.

However, precautions must be taken to avoid applications of any voltage higher than maximum rated voltages to this high-impedance circuit. For proper operation, VIN a nd VOUT should be constrained to the range GND≤(VIN or VOUT)≤VCC. Unused inputs must always be tied to an appropriate logic voltage level (e.g., either GND or V ). CC Unused outputs must be left open.
