74AHC164 Overview
The 74AHC/AHCT164 shift registers are high-speed silicon-gate CMOS devices and are pin patible with Low power Schottky TTL (LSTTL). They are specified in pliance with JEDEC standard No. The 74AHC/AHCT164 input signals are 8-bit serial through one of two inputs (Dsa or Dsb);.
74AHC164 Key Features
- Balanced propagation delays
- All inputs have Schmitt-trigger actions
- Inputs accept voltages higher than VCC
- For AHC only: operates with CMOS input levels
- For AHCT only: operates with TTL input levels
- Specified from -40 to +85 °C and from -40 to +125 °C
