description
These
quadruple
2-line
to
1-line
data
selectors/multiplexers are designed for 4.5-V to
5.5-V VCC operation.
The ’AHCT157 devices feature a common strobe
(G) input. When the strobe is high, all outputs are
low. When the strobe is low, a 4-bit word is
selected from one of two sources and is routed to
the four outputs. The devices provide true data.
The
SN54AHCT157
is
characterized
for
operation over the full military temperature range
of –55
°C to 125°C. The SN74AHCT157 is
characterized for operation from –40
°C to 85°C.
