SN74LS353

The SN74LS353 is designed as a dual 4-input multiplexer with 3-state outputs. It can select two bits of data from four sources using common select inputs. The outputs may be individually switched to a high impedance state with a high on the respective output enable (E0) inputs, allowing the outputs to interface directly with bus oriented systems.

SN74LS353 has four features. (1)Inverted version. (2)Schottky process for high speed. (3)Multifunction capability. (4)Input clamp diodes limit high speed termination effects. Those are all the main features.

(2)Its operating ambient temperature range would be min 0°C and typ 25°C and max 70°C. (3)Its output current high level would be max -2.6mA. (4)Its output current low level would be max 24mA.

Also some DC characteristics SN74LS353 are concluded as follow. (1)Its input high voltage would be min 2.0V with conditions of guaranteed input high voltage for all inputs. (2)Its input low voltage would be max 0.8V with conditions of guaranteed input low voltage for all inputs. (3)Its input clamp diode voltage would be typ -0.65V and max -1.5V with condition of Vcc=min, Iin=-18mA. (4)Its output high voltage would be min 2.4V and typ 3.1V. (5)Its output low voltage would be typ 0.25V and max 0.4V with condition of Iol=12mA. (6)Its input high current would be max 20uA with condition of Vcc=max and Vin=2.7V and it would be max 0.1mA with condition of Vcc=max and Vin=7.0V. (7)Its input low current would be max -0.4mA. (8)Its short circuit current would be min -20mA and max -130mA with condition of Vcc=max. (9)Its power supply current would be max 14mA with condition of Vcc=max.

And some AC characteristics SN74LS353 are concluded into several points as follow. (1)Its propagation delay data to output would be typ 11ns and max 25ns. (2)Its propagation delay select to output would be typ 20ns and max 45ns. (3)Its output enable time to high level would be typ 11ns and max 23ns. And so on.
