SN74LS33

The SN74LS33 is designed as quad 2-input nor buffer which would be low power schottky type.

Some guaranteed operating ranges SN74LS33 have been concluded into several points as follow. (1)Its supply voltage range would be min 4.75V and typ 5.0V and max 5.25V. (2)Its operating ambient temperature range would be min 0°C and typ 25°C and max 70°C. (3)Its output voltage high level would be max 5.5V. (4)Its output current low level would be max 24mA.

Also some DC characteristics SN74LS33 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 current would be max 250uA with conditions of Vcc=min, Voh=max. (5)Its output low voltage would be typ 0.25V and max 0.4V with condition of Iol=12mA, Vcc=Vcc min, Vin=Vil or Vih per truth table. (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 with condition of Vcc=max, Vin=0.4V. (8)Its power supply current would be max 3.6mA for output high and would be max 13.8mA for output low with condition of Vcc=max.

And some AC characteristics SN74LS33 are concluded into several points as follow. (1)Its turn off delay input to output would be typ 20ns and max 32ns. (2)Its turn on delay input to output would be typ 18ns and max 28ns with conditions of Vcc=5.0V, Rl=667 ohms and Cl=45pF. And so on. At present we have not got so much information about it and we would try hard to get more. If you have any question or suggestion or want to know more information please contact us for details.
