TC74HC158AP/AF Quad 2-Channel
Multiplexer (inverting)
The TC74HC157A and TC74HC158A are high speed CMOS
2-CHANNEL MULTIPLEXERs fabricated with silicon gate
C
2
MOS technology.
They achieve the high speed operation similar to equivalent
LSTTL while maintaining the CMOS low power dissipation.
The TC74HC158A is an inverting multiplexer while the
TC74HC157A is a non-inverting.
When
STROBE is held high, selection of data is inhibited and
all the outputs become low in the case of HC157A or high in the
case of HC158A.
The SELECT decoding determines whether the A or B inputs
get transferred to their corresponding Y (
Y) outputs.
All inputs are equipped with protection circuits against static
discharge or transient excess voltage.

Note 1: 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).
Note 2: 500 mW in the range of Ta = −40 to 65°C. From Ta = 65 to 85°C a derating factor of −10 mW/°C shall be
applied until 300 mW.
