TC74HC158AP/AF/AFN Quad 2-Channel
Multiplexer (inverting)
The TC74HC157A and TC74HC158A are high speed CMOS
2-CHANNEL MULTIPLEXERs fabricated with silicon gate
C2MOS 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: xxxFN (JEDEC SOP) is not available in
Japan.
