SN74AHC1G02DCKR

Overview

The SN74AHC1G02DCKR is a single-channel, 2-input positive logic NOR gate from Texas Instruments' AHC series. It operates within a supply voltage range of 2V to 5.5V and features Schmitt-trigger inputs for noise tolerance. The device provides an output drive capability of ±8mA at 5V and exhibits a maximum propagation delay of 6.5ns at 5V. It is housed in a SC-70 (SOT-353) surface-mount package with five pins.

Feature Summary

• Implements Boolean NOR function Y = A + B using positive logic
• Schmitt trigger inputs accommodate slow rise and fall times
• Low quiescent current consumption of 10µA maximum
• Supports wide operating voltage range from 2V to 5.5V

Applications

• Automotive infotainment systems
• Printer control circuits
• Digital camera modules
• PC and notebook peripherals
• Smart meters

Procurement Notes

Verify the specific suffix 'DCKR' corresponds to the SC-70 package and tape-and-reel orientation. Confirm RoHS compliance status and ensure the component meets required temperature ratings for the intended environment. Cross-reference datasheet electrical characteristics against system requirements before finalizing procurement.

Selection Notes

Select this component when a compact NOR gate with Schmitt trigger input hysteresis is required. The AHC series offers high-speed performance comparable to standard 74HC devices but with improved switching characteristics. Ensure the design accommodates the 2V to 5.5V supply range and utilizes the low static current benefits for power-sensitive applications.

Part Context

This part belongs to the Texas Instruments SN74AHC1Gxx family of advanced high-speed CMOS logic gates. The AHC series is designed for high-speed digital applications requiring low power dissipation. The SN74AHC1G02 specifically provides a single 2-input NOR function in a minimal footprint suitable for space-constrained PCB layouts.
