74VHC161FT,74VHC163FT

CMOS Digital Integrated Circuits Silicon Monolithic

74VHC161FT,74VHC163FT

1. Functional Description

• Synchronous Presettable 4-Bit Counter

74VHC161FT: Binary , Asynchronous Clear

74VHC163FT: Binary , Synchronous Clear

2. General

The 74VHC161FT and 74VHC163FT are advanced high speed CMOS SYNCHRONOUS PRESETTABLE 4 BIT

BINARY COUNTERs fabricated with silicon gate C

MOS technology.

They achieve the high speed operation similar to equivalent Bipolar Schottky TTL while maintaining the CMOS

low power dissipation.

The CK input is active on the rising edge. Both LOAD and CLR inputs are active on low logic level.

Presetting of each IC's is synchronous to the rising edge of CK.

The clear function of the 74VHC163FT is synchronous to CK, while the 74VHC161FT are cleared asynchronously.

Two enable inputs (ENP and ENT) and CARRY OUTPUT are provided to enable easy cascading of counters,

which facilitates easy implementation of n-bit counters without using external gates.

An input protection circuit ensures that 0 to 5.5 V can be applied to the input pins without regard to the supply

voltage. This device can be used to interface 5 V to 3 V systems and two supply systems such as battery back up.

This circuit prevents device destruction due to mismatched supply and input voltages
