74253 LOGIC GATE

Description:

Name: 74253 LOGIC GATE
SKU: LG074253
Availability: InStock

Each of these Schottky-clamped data selectors/multiplexers contains inverters and drivers to supply fully complementary, on-chip, binary decoding data selection to the
AND-OR gates. Separate output control inputs are provided for each of the two four-line sections. The 3-STATE outputs can interface directly with 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.

Features:

3-STATE version of DM74LS153 with same pinout
Schottky-diode-clamped transistors
Permit multiplexing from N-lines to one line
Performs parallel-to-serial conversion
Strobe/output control
High fanout totem-pole outputs
Typical propagation delay
Data to output 12 ns
Select to output 21 ns
Typical power dissipation 35 mW
