SN74ALS00AN

SN74ALS00AN Description

The SN74ALS00AN from Texas Instruments is a quad 2-input NAND gate integrated circuit (IC) belonging to the 74ALS series, designed for high-speed logic operations. Housed in a 14-pin DIP (Dual Inline Package), it operates within a 4.5V to 5.5V supply range, making it compatible with standard 5V TTL logic systems. With a maximum propagation delay of 11ns at 5V and 50pF load, it ensures efficient signal processing in digital circuits. The device features low power consumption (output current: 400µA high, 8mA low) and robust noise immunity, with input logic levels defined as 0.8V (Low) and 2V (High). Its through-hole mounting simplifies prototyping and legacy system integration.
