The TC74VHC 161 and 163 are advanced high speed CMOS

SYNCHRONOUS PRESETTABLE 4 BIT BINARY COUNTERs

fabricated with silicon gate C²MOS 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 TC74VHC163 is synchronous to CK,

while the TC74VHC161 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.
