XL74LS02 – Quad 2-Input NOR Gate – Xinluda

The XL74LS02 from Xinluda is a quadruple 2-input positive NOR gate in the 74LS low-power Schottky TTL family, supplied in a surface-mount SOP-14 package. It is a pin-to-pin compatible alternative to the industry-standard SN74LS02.

The XL74LS02 is a quadruple 2-input positive NOR gate manufactured by Xinluda (Xinluda Information Technology Co., Ltd.). It integrates four independent 2-input NOR gates on a single chip, built on the proven 74LS low-power Schottky TTL process for fast switching speed combined with reduced power consumption. The XL74LS02 is offered in a surface-mount SOP-14 package and serves as a pin-to-pin compatible replacement for the industry-standard SN74LS02, making it a practical drop-in option for designs needing a domestic or alternate source.
