74HC21 Description

Short technical summary and product information.

The 74HC21 is a high-speed CMOS (HC) integrated circuit that provides two independent 4-input AND gates. Each gate performs the logical AND function, where the output is HIGH only if all four inputs are HIGH.

This component is designed for low-power dissipation and complies with JEDEC standard no. 7A. It features ESD protection exceeding 2000V for HBM and 200V for MM. The operating voltage range is from 2V to 6V, making it suitable for various digital applications. The specified operating temperature range is -40°C to +125°C, ensuring reliable performance in diverse environments.

The 74HC21 is available in multiple package options, including SO14, SSOP14, and TSSOP14, all of which are surface-mount types. Its inputs include clamp diodes, which allow for the use of current-limiting resistors to interface inputs to voltages exceeding VCC.

This dual 4-input AND gate is a fundamental building block in digital logic circuits, used for implementing complex logic functions, data selection, and control signal generation.
