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.
