The SNx4xx00 devices contain four independent, 2-input NAND gates. The devices perform the Boolean function Y = A .B or Y = A + B in positive logic.
SN74LS00N is a 14-pin dual 4-input positive-NAND gate integrated circuit (IC) manufactured by Texas Instruments. It is part of the 74LS series of logic ICs.
Description: The SN74LS00N is a dual 4-input positive-NAND gate. It contains two independent gates, each of which performs the logic NAND function. The inputs include clamp diodes that enable the use of current limiting resistors to interface inputs to voltages in excess of VCC.
Features:
rn Low power consumption
rn High noise immunity
rn High speed operation
rn High fan-out capability
rn High input impedance
rn Low input current
Applications: The SN74LS00N is commonly used in applications such as logic gates, flip-flops, counters, and shift registers. It can also be used in computer systems, communication systems, and instrumentation systems.
