description/ordering information
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.
