1. General description

The 74HC164-Q100; 74HCT164-Q100 is an 8-bit serial-in/parallel-out shift register. The device

features two serial data inputs (DSA and DSB), eight parallel data outputs (Q0 to Q7). Data is

entered serially through DSA or DSB and either input can be used as an active HIGH enable for

data entry through the other input. Data is shifted on the LOW-to-HIGH transitions of the clock

(CP) input. A LOW on the master reset input (MR) clears the register and forces all outputs LOW,

independently of other inputs. Inputs include clamp diodes that enable the use of current limiting

resistors to interface inputs to voltages in excess of VCC.

This product has been qualified to the Automotive Electronics Council (AEC) standard Q100

(Grade 1) and is suitable for use in automotive applications.
