Fairchild DM74LS161AN

Двоичный счетчик14,75 В ~ 5,25 В

Overview

The DM74LS161AN is a 4-bit synchronous binary counter IC that can count clock pulses or divide frequencies. This counter is entirely programmable, allowing the outputs to be set at any level. The counter's actions (enabled, disabled, loading, or counting) depend exclusively on meeting the established setup and hold time requirements. It's designed for synchronous counting applications where precise count control is required. For more details about the counter pinout, circuit diagram, etc., check the DM74LS163AN datasheet.

Available in a 16-pin DIP package
