Key Features
- Gated serial data inputs, allowing either input to be used as an active HIGH enable for data entry through the other input.
- Asynchronous master reset input (MR) that clears the register and forces all outputs LOW, independently of other inputs.
- Wide supply voltage range from 2.0 to 6.0 V.
- CMOS low power dissipation and high noise immunity.
- Compliance with JEDEC standards (JESD8C and JESD7A).
- Latch-up performance exceeds 100 mA per JESD 78 Class II Level B.
- ESD protection: HBM exceeds 2000 V and CDM exceeds 1000 V.
- Multiple package options, including TSSOP14 with Side-Wettable Flanks for Automatic Optical Inspection (AOI) of solder joints.
Applications
The 74HC164PW-Q100118 is suitable for a variety of applications, including:
