Product data sheet

1. General description

The 74AHC164; 74AHCT164 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 are overvoltage tolerant. This feature allows the use of these devices as translators

in mixed voltage environments.

2. Features

• Wide supply voltage range from 2.0 V to 5.5 V

• Overvoltage tolerant inputs to 5.5 V

• High noise immunity

• CMOS low power dissipation

• Balanced propagation delays

• All inputs have Schmitt-trigger actions

• Input levels:

• For 74AHC164: CMOS level

• For 74AHCT164: TTL level

• ESD protection:

• HBM JESD22-A114F exceeds 2000 V

• MM JESD22-A115-A exceeds 200 V

• CDM JESD22-C101C exceeds 1000 V

• Latch-up performance exceeds 100 mA per JESD 78 Class II Level A

• Multiple package options

• Specified from -40 °C to +85 °C and from -40 °C to +125 °C
