SN74HC21NSR Description

Short technical summary and product information.

The SN74HC21NSR is a Texas Instruments 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 operates with a wide voltage range of 2V to 6V and is suitable for a broad spectrum of applications.

 

Key electrical characteristics include a maximum propagation delay of 19ns at 6V and 50pF, and an output current drive of 5.2mA. The input logic levels are specified between 1.5V and 4.2V. The operating temperature range is -40°C to 85°C, making it robust for various environmental conditions.

 

Packaged in a 14-SOIC (0.209", 5.30mm Width) surface-mount configuration, the SN74HC21NSR is designed for ease of integration into printed circuit boards. Its standard CMOS technology offers significant power reduction compared to LSTTL logic ICs and supports fanout up to 10 LSTTL loads.
