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.
SN54F157A . . . FK PACKAGE
(TOP VIEW)
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.
