description

GND 12

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.

SN54AS250A . . . FK PACKAGE

(TOP VIEW)

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

thehigh-impedancestate, theoutputneitherloads

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.

NC – No internal connection
