MC5474F164 Datasheet, PDF (1/3 Pages) Motorola, Inc – 8-BIT SERIAL-IN, PARALLEL-OUT SHIFT REGISTER

8-BIT SERIAL-IN, PARALLEL-OUT
SHIFT REGISTER
The MC54/74F164 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.
• Typical Shift Frequency of 90 MHz
• Asynchronous Master Reset
• Gated Serial Data Input
• Fully Synchronous Data Transfers
