8-bit serial-in/parallel-out shift register
Rev. 1 — 5 July 2013
Product data sheet
1. General description
The 74AHC164-Q100; 74AHCT164-Q100 shift register is a high-speed Si-gate CMOS
device and is pin compatible with Low-power Schottky TTL (LSTTL). It is specified in
compliance with JEDEC standard No. 7A.
The 74AHC164-Q100; 74AHCT164-Q100 input signals are 8-bit serial through one of two
inputs (DSA or DSB). Either input can be used as an active HIGH enable for data entry
through the other input. Both inputs must be connected together or an unused input must
be tied HIGH.
Data shifts one place to the right on each LOW-to-HIGH transition of the clock input (CP).
It enters into output Q0, which is a logical AND of the two data inputs (DSA and DSB).
These data inputs existed one set-up time, prior to the rising clock edge.
A LOW-level on the master reset (MR) input overrides all other inputs and clears the
register asynchronously, forcing all outputs LOW.
This product has been qualified to the Automotive Electronics Council (AEC) standard
Q100 (Grade 1) and is suitable for use in automotive applications.
