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.

Note:
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).
