TC7MH157FK
TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic
TC7MH157FK
Quad 2-Channel Multiplexer
The TC7MH157FK is an advanced high speed CMOS quad
2
2-channel multiplexer fabricated with silicon gate C MOS
technology.
It achieves the high speed operation similar to equivalent
bipolar schottky TTL while maintaining the CMOS low power
dissipation.
It consists of four 2-input digital multiplexers with common
select and strobe inputs.
When the strobe input (ST) is held “H” level, selection of data is
inhibited and all the outputs become “L” level.
The SELECT decoding determines whether the A or B inputs
get routed to their corresponding Y outputs.
An Input protection circuit ensures that 0 to 5.5 V can be
applied to the input pins without regard to the supply voltage.
Weight: 0.02 g (typ.)
This device can be used to interface 5 V to 3 V systems and on 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).
