Overview
The 74HC163D-Q100J, produced by Nexperia USA Inc., is a presettable synchronous 4-bit binary counter with an internal look-ahead carry. This component is part of the 74HC family, which operates at CMOS logic levels. It 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, and it includes a synchronous reset feature that can be triggered by a LOW at the master reset input (MR), regardless of other input levels.
