description
The
′F157A is a quadruple 2-input data
selector/multiplexer featuring 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
′F157A provides true data.
The SN54F157A is characterized for operation
over the full military temperature range of 55
°C
to 125
°C. The SN74F157A is characterized for
operation from 0
°C to 70°C.
