Overview
The 74HC161D-Q100J, produced by Nexperia USA Inc., is a synchronous presettable 4-bit binary counter with an internal look-ahead carry. This component is designed for high-speed counting applications and features synchronous operation, where all flip-flops are clocked simultaneously on the positive-going edge of the clock (CP). The counter allows for presetting the outputs (Q0 to Q3) to either HIGH or LOW levels, and it includes asynchronous reset functionality. The 74HC161D-Q100J is qualified to the Automotive Electronics Council (AEC) standard Q100 (Grade 1), making it suitable for use in automotive applications.
