description
The
′AS250A devices provide full binary decoding
to select 1-of-16 data inputs or use sources as an
input with an inverting W output. The selected
sources
are
buffered
with
symmetrical
propagation delay times. This reduces the
possibility of transients occurring at the output.
A buffered output-enable (OE) input can be used
for n-line to 1-line cascading. Taking OE high
places the output in the high-impedance state. In
the high-impedance state, the output neither loads
nor drives the bus lines significantly.
OE does not affect the internal operations of the
data selector/multiplexer. New data can be set up
while the outputs are disabled.
The SN54AS250A is characterized for operation
over the full military temperature range of 55
°C
to 125
°C. The SN74AS250A is characterized for
operation from 0
°C to 70°C.
