The TC74AC161 and 163 are advanced high speed CMOS
SYNCHRONOUS PRESETTABLE COUNTERs fabricated with
silicon gate and double-layer metal wiring 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 these IC’s is synchronous to the rising edge of CK.
The clear function of the TC74AC163 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 facilitates
easy implementation of n-bit counters without using external
gates.
All inputs are equipped with protection circuits against static
discharge or transient excess voltage.

Note 1: Exceeding any of the absolute maximum ratings, even briefly, lead to deterioration in IC performance or
even destruction.
Using continuously under heavy loads (e.g. the application of high temperature/current/voltage and the
significant change in temperature, etc.) may cause this product to decrease in the reliability significantly
even if the operating conditions (i.e. operating temperature/current/voltage, etc.) are within the absolute
maximum ratings and the operating ranges.
Please design the appropriate reliability upon reviewing the Toshiba Semiconductor Reliability Handbook
(“Handling Precautions”/Derating Concept and Methods) and individual reliability data (i.e. reliability test
report and estimated failure rate, etc).
Note 2: 500 mW in the range of Ta = −40 to 65°C. From Ta = 65 to 85°C a derating factor of −10 mW/°C should be
applied up to 300 mW.

Note 1: For TC74AC161 only
Note 2: CPD is defined as the value of the internal equivalent capacitance which is calculated from the operating
current consumption without load.
Average operating current can be obtained by the equation:
ICC (opr) = CPD·VCC·fIN + ICC
When the outputs drive a capacitive load, total current consumption is the sum of CPD, and ΔICC which is
