HD74ACT164 Datasheet | Hitachi Semiconductor

HD74AC164/HD74ACT164 Serial-In, Parallel-Out Shift Register Description The HD74AC164/HD74ACT164 is a high-speed 8-bit serial-in/parallel-out shift register. Serial data is entered through a 2-input AND gate synchronous with the Low-to-High transition of the clock. The device Features an asynchronous Master Reset which clears the register, setting all outputs Low independent of the clock. Features - Outputs Source/Sink 24 mA - HD74ACT164 has TTL-patible Inputs Pin Arrangement A 1 B 2 Q0 3 Q1 4 Q2 5 Q3 6 GND 7 (Top view) 14 VCC 13 Q7 12 Q6 11 Q5 10 Q4 9 MR 8 CP HD74AC164/HD74ACT164 Logic Symbol A B CP MR Q0 Q1 Q2 Q3 Q4 Q5 Q6 Q7 Pin Names A, B CP MR Q0 to Q7 Data Inputs Clock...
