TC7MH161,163FK
TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic
TC7MH161FK,TC7MH163FK
Synchronous Presettable 4-Bit Binary Counter
TC7MH161FK Asynchronous Clear
TC7MH163FK Synchronous Clear
The TC7MH161FK and 163FK are advanced high speed CMOS
synchronous presettable 4-bit binary counters fabricated with
2
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 TC7MH163FK is synchronous to CK,
Weight: 0.02 g (typ.)
while the TC7MH161FK 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).
