Key Features
- Two serial data inputs (DSA and DSB) and eight parallel data outputs (Q0 to Q7)
- Data is entered serially through DSA or DSB, with either input capable of acting 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
- Asynchronous master reset (MR) clears the register and forces all outputs LOW, independently of other inputs
- Inputs include clamp diodes for interfacing with voltages in excess of VCC
- CMOS low power dissipation
- 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 (ANSI/ESDA/JEDEC JS-001 class 2 exceeds 2000 V), CDM (ANSI/ESDA/JEDEC JS-002 class C3 exceeds 1000 V)
- Multiple package options, including TSSOP14 with Side-Wettable Flanks for Automatic Optical Inspection (AOI) of solder joints
Applications
The 74HC164PW-Q100J is particularly suited for automotive applications due to its AEC-Q100 (Grade 1) qualification. It can be used in various automotive systems that require reliable and efficient serial-to-parallel data conversion. Other potential applications include industrial control systems, consumer electronics, and any environment where low power consumption and high noise immunity are critical.
