NTE74LS352 Integrated Circuit TTL − Dual 4−Line−to−1−Line Data

NTE74LS352
Integrated Circuit
TTL − Dual 4−Line−to−1−Line Data Selector/Multiplexer
Description:
The NTE74LS352 is a dual 4−line−to−1−line data selector/multiplexer in a 16−Lead plastic DIP type
package that contains inverters and drivers to supply fully complementary, on−chip, binary decoding
data selection to the AND−OR−invert gates. Separate strobe inputs are provided for each of the two
four−line sections.
Features:
D Inverting Version of NTE74LS153
D Schottky−Diode−Clamped Transistors
D Permits Multiplexing from N Lines to One Line
D Performs Parallel−to−Serial Conversion
D Fully Compatible with most TTL Circuits
D Low Power Dissipation (Enabled); 31mW (Typ)

Note 2. .For conditions shown as MIN or MAX, use the appropriate value specified under “Recommended
Operation Conditions”.
Note 3. All typical values are at VCC = 5V, TA = +25C.
Note 4. Not more than one output should be shorted at a time, and duration of the short−circuit
should not exceed one second.
Note 5. ICCL is measured with the outputs open and all inputs grounded.
