SN74HC21PWR Description

Short technical summary and product information.

The Texas Instruments SN74HC21PWR is a high-performance integrated circuit featuring two independent 4-input AND gates. Each gate performs the Boolean function Y = A ● B ● C ● D in positive logic. This device is designed for a wide operating voltage range of 2V to 6V, making it versatile for different system requirements.

 

With a drive strength of 5.2mA and a maximum propagation delay of 19ns at 6V and 50pF, the SN74HC21PWR offers efficient performance. It supports fanout up to 10 LSTTL loads and provides significant power reduction compared to LSTTL logic. The operating temperature range is -40°C to +85°C, ensuring reliability in various environmental conditions.

 

The SN74HC21PWR comes in a compact 14-TSSOP (0.173", 4.40mm Width) package, designed for surface mounting. Its buffered inputs contribute to stable operation. This logic gate is suitable for digital signal processing, control systems, and general-purpose logic functions where AND operations are required.
