IN74HC374A

TECHNICAL DATA IN74HC374A Octal 3-State Noninverting D Flip-Flop High-Performance Silicon-Gate CMOS The IN74HC374A is identical in pinout to the LS/ALS374. The device inputs are compatible with standard CMOS outputs; with pullup resistors, they are compatible with LS/ALSTTL outputs. Data meeting the setup and hold time is clocked to the outputs with the rising edge of the Clock. The Output Enable input does not affect the states of the flip-flops, but when Output Enable is high, the outputs are forced to the high-impedance state; thus, data may be stored even when the outputs are not enabled. 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 IN74HC374AN Plastic IN74HC374ADW SOIC TA = -55° to 125° C for all packages PIN ASSIGNMENT LOGIC DIAGRAM FUNCTION TABLE PIN 20=VCC PIN 10 = GND Inputs Output Enable L L L H L,H, X Clock D H L X X Output Q H L no change Z w w w .d e e h s a t a . u t4 m o c X = don’t care Z = high impedance 1 www.DataSheet4U.com IN74HC374A MAXIMUM RATINGS* Symbol VCC VIN VOUT IIN IOUT ICC PD Tstg 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 Temper...
