TOSHIBA CMOS Digital Integrated Circuit
Silicon Monolithic
TC7WH34FU,TC7WH34FK
Triple Non-Inverter
The TC7WH34 is an advanced high speed CMOS Non-Inverter
fabricated with silicon gate CMOS technology.
It achieves the high speed operation similar to equivalent
Bipolar Schottky TTL while maintaining the CMOS low power
dissipation. The internal circuit is composed of 3 stages including
buffer output, which provide high noise immunity and stable
output. An input protection circuit ensures that 0 to 7 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: 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).
