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 drives the bus line to a high
or low logic level. Each output has its own
output-enable (OE) input. The output is disabled
when OE is high.
The SN54ALS253 is characterized for operation
over the full military temperature range of 55
°C
to 125
°C. The SN74ALS253 and SN74AS253A
are characterized for operation from 0
°C to 70°C.
