HD74LS00

The HD74LS00 is designed as one kind of quadruple 2-input positive NAND gates.

Some electrical characteristics of HD74LS00 have been concluded into several points as follow. (1)Its input voltage high level would be min 2.0V. (2)input voltage low level would be max 0.8V. (3)Its output voltage high level would be min 2.7V. (4)Its output voltage low level would be max 0.5V at Iol=8mA and would be max 0.4V at Iol=4mA. (5)Its input current high level would be max 20uA. (6)Its input current low level would be max -0.4mA. (7)Its input current would be max 0.1mA for Ii. (8)Its short circuit output current would be min -20mA and max -100mA. (9)Its supply current high level would be typ 0.8mA and max 1.6mA. (10)Its supply current low level would be typ 2.4mA and max 4.4mA. (11)Its input clamp voltage would be max -1.5V with test conditions of Vcc=4.75V and Iin=-18mA. (12)Its propagation delay time would be typ 9ns and max 15ns for tPLH and would be typ 10ns and max 15ns for tPHL. And so on. Those are all the main elextrical characteristics.
