TC7MH4040FK

Note: Exceeding any of the absolute maximum ratings, even briefly, may 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).

The TC7MH4040FK is an advanced high speed CMOS 12-stage ripple-carry binary counter fabricated with silicon gate C2MOS technology.

TC7MH4040FK achieves the high speed operation similar to equivalent bipolar schottky TTL while maintaining the CMOS low power
dissipation.

Setting CLR to high resets the counter to low.

A negative transition on the CK input brings one increment into the counter.

The TC7MH4040FK  provides all divided output stages, and at Q12, a 1/4096 divided frequency will be output.

An input protection circuit ensures that 0 to 5.5 V can be applied to the input pins without regard to the supply voltage.

The TC7MH4040FK 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.
