Description
74LS00 is one of the famous and most basic gates from a family of logic gates. which is the Quad 2 input NAND Gate, Due to the NAND gate known as universal gate, 74LS00 can be converted into OR and NOT gate easily.
74LS00 FEATURES
- This IC can be used as a NAND gate however due to the universality of the NAND gate, it can be converted into other gates easily.
- The internal structure of IC is TTL based that’s why its output also comes in TTL.
- It can be used in HIGH-frequency systems.
SPECIFICATIONS
- The operating voltage of 74LS00 is 4.75 to 5.25.
- The maximum power supply voltage could be at 7V but in case of a minor increase in voltages above 7V, the IC could burn easily.
- The maximum current draw from each gate at the output will be 8mA.
- IC has a maximum ESD of about 3.5KV.
- The IC has a typical rise and fall time is 15ns.
- IC has a maximum operating temperature is about 0 – 75 degrees.
- The Low-level input voltage at the gate will be 0.8 and the HIGH level will be 2V.
- IC has an internal clamp voltage of about -1.5V.
