SN74AHC1G02DRLR

Overview

The SN74AHC1G02DRLR is a single-channel, two-input positive-logic NOR gate manufactured by Texas Instruments. It operates within a supply voltage range of 2 V to 5.5 V and features Schmitt-trigger inputs for noise tolerance. The device provides an output drive capability of ±8 mA at 5 V and achieves a maximum propagation delay of 6.5 ns at 5 V. It functions across an extended temperature range from -40 °C to +125 °C and is housed in a compact SOT-553 (DRL) five-pin package.

Feature Summary

• Implements Boolean logic function Y = A + B using positive logic
• All inputs feature Schmitt trigger action for slow signal processing
• Supports wide operating voltage range from 2 V to 5.5 V

Applications

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

Procurement Notes

Verify the specific ordering suffix DRLR against the manufacturer's current datasheet to confirm the SOT-553 package type and reel specifications. Ensure the component meets RoHS compliance requirements for your region. Confirm that the intended application environment falls within the specified -40 °C to +125 °C operating temperature range before finalizing procurement.

Selection Notes

Select this component when a single two-input NOR gate is required with Schmitt trigger input characteristics. It is suitable for designs needing operation across a broad voltage spectrum between 2 V and 5.5 V. The low static current consumption makes it appropriate for power-sensitive applications requiring minimal quiescent power draw.

Part Context

This part belongs to the SN74AHC1G02 family of single-function gates. It is distinct from NAND or AND variants within the broader SN74AHC series. The device is designed for general-purpose digital logic applications requiring high-speed switching and robust noise immunity in small form-factor surface-mount packages.

Replacement Considerations

Consult official substitution guides for equivalent parts such as the SN74AHC1G02DR or SN74AHC1G02DBV if different packaging options are required. Verify pinout compatibility and electrical parameters before replacing the original component.
