SN74AS253AD-SN74AS253AN
Dual 1-Of-4 Data Selectors/Multiplexers With 3-State Outputs
Package Options Include PlasticSmall-Outline (D) Packages, Ceramic Chip
Carriers (FK), and Standard Plastic (N) and
Ceramic (J) 300-mil DIPs
descriptionThese 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.
FUNCTION TABLE Select inputs A and B are common to both sections.
