The MC74HC163AN is an integrated circuit (IC) component that belongs to the 74HC family of high-speed CMOS logic devices. It is a 4-bit binary counter with synchronous reset functionality. Here is an overview of the key features of the MC74HC163AN:
1. Binary Counter: The MC74HC163AN is designed to function as a synchronous 4-bit binary counter. It can count from 0 to 15 (in binary) on the four output pins, labeled Q0-Q3.
2. Synchronous Operation: The counter operates synchronously, meaning that the count changes simultaneously with input clock transitions. This ensures accurate and reliable counting without any timing issues.
3. Asynchronous Reset: The MC74HC163AN includes an asynchronous reset input (labeled MR - Master Reset) that allows the counter to be reset to 0000 (decimal 0) before counting starts or at any time during counting. When MR is activated, all the outputs are forced to logic low.
4. Multiple Clocking Options: The counter can be clocked through two different input clock options, labelled CP (Count Pulse) and CLOCK INH (Clock Inhibit). The CP input is the primary clock signal that increments the counter on rising edges. The CLOCK INH input, when active low, inhibits the CP input and suppresses counting
