1. General description

The 74HC164; 74HCT164 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

diodes. This enables the use of current limiting resistors to interface inputs to voltages in

excess of V

2. Features and benefits

 Input levels:

 For 74HC164: CMOS level

 For 74HCT164: TTL level

 ESD protection:

 HBM JESD22-A114F exceeds 2000 V

 MM JESD22-A115-A exceeds 200 V.

 Multiple package options

 Specified from 40 C to +85 C and 40 C to +125 C.
