SN54ALS253, Dual 1-Of-4 Data Selectors/Multiplexers With 3-State Outputs
DEVICE STATUS: ACTIVE
l
3-State Versions of the ALS153 and SN74AS153
l
Permits Multiplexing From n Lines to
One Line
l
Performs Parallel-to-Serial Conversion
l Package Options Include Plastic Small-Outline (D) Packages, Ceramic Chip Carriers (FK),
and Standard Plastic (N) and Ceramic (J) 300-mil DIPs
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 (
) input. The output is disabled when
is high.
The SN54ALS253 is characterized for operation over the full military temperature range of -
