SN74HC02DT

Overview

The SN74HC02DT is a quadruple 2-input positive-NOR gate manufactured by Texas Instruments. It belongs to the HC/UH series and utilizes CMOS technology. The device is housed in a 14-pin Small Outline Integrated Circuit (SOIC) package with a width of 0.25 inches. It operates within an ambient temperature range of -40°C to +85°C. The logic family supports standard CMOS input levels and provides push-pull outputs.

Feature Summary

• Contains four independent 2-input NOR logic gates
• CMOS technology for low power consumption
• Industrial temperature rating for wide operating conditions

Applications

• Digital logic circuit design
