74AHC164; 74AHCT164
8-bit serial-in/parallel-out shift register
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.
Features and benefits
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
