8-BIT PARALLEL-OUT SERIAL SHIFT REGISTERS

Description

Pin Assignments

The 74AHC164 is a serial input 8-bit edge-triggered shift register that

has outputs from each of eight stages.

(Top View

)

SERIAL DATA INPUT PINS

The serial input data is entered at pin SDA or pin SDB as these are

logically ANDED. Either input could be used as an active HIGH

enable with data entry on the other pin. If a single input is desired, the

pins can be tied together or the unused input can be tied HIGH.

Vcc

DSA

DSB

DATA ENTRY

Data is shifted into Q0 from the serial input pins on each LOW to

HIGH transition of the CP pin. Also during the CP edge the data is

transferred from each Qn to Qn+1. The serial data on pins DSA and

DSB must be stable before and after the CP rising edge to meet the

set-up and hold timing requirements.

GND

SO-14 / TSSOP-14 / PDIP-14

RESET

When asserted LOW the Master Reset (MR ) pin sets all Qn to LOW.

This action does not depend on the condition of serial input or clock

pins. The MR must be asserted HIGH for a recovery time before the

next CP positive edge pulse.
