TC7WH157FU/FK  
TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic  
TC7WH157FU,TC7WH157FK  
2-Channel Multiplexer  
The TC7WH157 is an advanced high speed CMOS 2-Channel  
Multiplexer 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. It consists of 2-input digital multiplexer with  
common select and strobe inputs.  
TC7WH157FU  
When the STROBE input 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 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).
