SN74HC21PWT Description

Short technical summary and product information.

The SN74HC21PWT from Texas Instruments is a high-speed CMOS device containing two independent 4-input AND gates. Each gate performs the Boolean function Y = A ● B ● C ● D in positive logic.

This AND gate operates over a wide voltage range of 2V to 6V, making it suitable for various applications. It offers a maximum propagation delay of 19ns at 6V and 50pF, with a drive strength of 5.2mA. The device features standard CMOS input type and push-pull output type, with buffered inputs for enhanced signal integrity.

Packaged in a 14-TSSOP surface mount configuration, the SN74HC21PWT is designed for efficient board space utilization. It operates within a temperature range of -40°C to 85°C and supports fanout up to 10 LSTTL loads, providing significant power reduction compared to LSTTL logic ICs.

This component is ideal for digital logic designs requiring reliable AND gate functionality. Its wide operating voltage and temperature range, combined with its high-speed performance, make it a versatile choice for embedded systems and control circuits.
