description
These
quadruple
2-line
to
1-line
data
selectors/multiplexers are designed for 2-V to
5.5-V VCC operation.
The ’AHC157 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 SN54AHC157 is characterized for operation
over the full military temperature range of –55
°C
to 125
°C. The SN74AHC157 is characterized for
operation from –40
°C to 85°C.
