Key Features
- Input Levels: CMOS level for 74HC164 and TTL level for 74HCT164.
- Gated Serial Data Inputs: Data can be entered serially through one of two inputs (DSA or DSB), with either input capable of acting as an active HIGH enable for data entry through the other input.
- Asynchronous Master Reset: A LOW on the master reset input (MR) clears the register and forces all outputs LOW, independently of other inputs.
- ESD Protection: HBM JESD22-A114F exceeds 2000 V and MM JESD22-A115-A exceeds 200 V.
- Wide Supply Voltage Range: Operates from 2.0 to 6.0 V.
- CMOS Low Power Dissipation: Low power consumption.
- High Noise Immunity: Enhanced noise immunity due to CMOS technology.
