TC74AC163FT

The TC74AC161 and TC74AC163FT are advanced high speed CMOS SYNCHRONOUS PRESETTABLE COUNTERs fabricated with silico
n gate and double-layer metal wiring C² MOS technology.

They achieve the high speed operation similar to equivalent  Bipolar Schottky TTL while maintaining the CMOS low powe
r dissipation.

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

Presetting of these TC74AC163FT!s is synchonous to the rising edge of CK

The clear function of the TC74AC163FT is synchronous to CK, while the TC74AC161 are cleared asynchronously.

Two enable inputs (ENP and ENT) and CARRY OUTPUT are provided to enable easy cascading of counters, which cilitates
easy implementation of n-bit counters without using external gates.

All TC74AC163FT inputs are equipped with protection circuits against static discharge or transient excess voltage.
