SN74LV21ADR Description

Short technical summary and product information.

The SN74LV21ADR from Texas Instruments is a dual 4-input positive-AND gate. It operates over a wide voltage range of 2V to 5.5V, making it versatile for various applications. This device offers a very high speed with a maximum propagation delay of 7ns at 5V and 50pF load capacitance.

 

Key features include over-voltage tolerant inputs and partial power-down capability using Ioff circuitry, which prevents damaging current backflow when the device is powered down. The SN74LV21ADR performs the Boolean function Y = A • B • C • D in positive logic.

 

This AND gate is available in a 14-SOIC surface mount package. It operates within an industrial temperature range of -40°C to 85°C. The device also exhibits good latch-up performance, exceeding 100 mA per JESD 78, Class II.

 

Applications for the SN74LV21ADR include general logic functions, signal gating, and control circuits where a reliable AND operation is required within a 2V to 5.5V system.
