description
These data selectors/multiplexers contain
inverters and drivers to supply full binary decoding
data selection to the AND-OR gates. Separate
output-control inputs are provided for each of the
two 4-line sections.
The 3-state outputs can interface with and drive
data lines of bus-organized systems. With all but
one of the common outputs disabled (at a
high-impedance state), the low impedance of the
single enabled output will drive the bus line to a
high or low logic level. Each output has its own
strobe (G) inputs. The output is disabled when its
strobe is high.
The SN54F253 is characterized for operation over
the full military temperature range of −55°C to
125°C. The SN74F253 is characterized for
operation from 0°C to 70°C.
