Fairchild MM74HC161N

Двоичный счетчик12 В ~ 6 В

Overview

The MM74HC161N is a high-speed CMOS integrated circuit that functions as a 4-bit synchronous binary counter. It can count up or down depending on the control inputs and is commonly used in various digital counting applications. For more details about this counter pinout, circuit diagram, etc can check the MM74HC161N datasheet. All flip-flops activate concurrently during the transition from LOW to HIGH on the CLOCK input signal. The counter can be preset via the LOAD input. The synchronization of the presetting for all four flip-flops aligns with the CLOCK's upward edge.

Wide supply voltage range: 2V to 6V
