Product Summary
The 74VHC161M is a 4-Bit Binary Counter with Asynchronous Clear fabricated with silicon gate CMOS technology. It achieves the high-speed operation similar to equivalent Bipolar Schottky TTL while maintaining the CMOS low power dissipation. The 74VHC161M is a high-speed synchronous modulo-16 binary counter. This device is synchronously presettable for application in programmable dividers and has two types of Count Enable inputs plus a Terminal Count output for versatility in forming synchronous multistage counters. The 74VHC161M has an asynchronous Master Reset input that overrides all other inputs and forces the outputs LOW. An input protection circuit insures that 0V to 7V can be applied to the input pins without regard to the supply voltage. This device can be used to interface 5V to 3V systems and two supply systems such as battery backup. This circuit prevents device destruction due to mismatched supply and input voltages.
