SN74AHCT1G32DBVT

Overview

The SN74AHCT1G32DBVT is a single 2-input positive-OR gate from the Texas Instruments 74AHC/74AHCT series. It operates within a supply voltage range of 2V to 5.5V and features CMOS logic technology. The device utilizes an SOT-5 package, also known as SC-70-5 or SOT-353, designed for surface-mount applications. It supports a wide operating temperature range from -40°C to +85°C. Key electrical characteristics include a maximum propagation delay of 7.5ns at 5V with a 50pF load, and output drive currents of 8mA for both high and low states.

Feature Summary

• Single-channel OR logic function providing two inputs and one output
• Compatible with standard 5V CMOS logic families via AHCT input structure
• Supports operation across a broad voltage range from 2V to 5.5V
• Designed for space-constrained surface-mount PCB layouts

Applications

• Digital signal routing in portable consumer electronics
• Logic level translation between 3.3V and 5V systems
• Signal combining in embedded control circuits
• General-purpose logic functions in industrial automation modules

Procurement Notes

Verify the specific suffix 'VT' against the manufacturer's official datasheet to confirm pinout compatibility and tape-and-reel specifications. Ensure the ordered component matches the required AEC-Q100 qualification status if automotive application is intended. Cross-reference the RoHS compliance status with current regulatory requirements before finalizing procurement orders.

Selection Notes

Select this component when a compact single-gate solution is required for 5V-compatible logic designs. The AHCT series ensures compatibility with older 5V TTL standards while supporting lower voltage operation down to 2V. Consider the SOT-5 footprint constraints and thermal performance limits during the initial schematic capture phase to ensure adequate board space and heat dissipation.

Part Context

This part belongs to the Texas Instruments 74AHC/74AHCT family of high-speed CMOS logic devices. The family is characterized by fast switching speeds and low power consumption. The 'AHCT' designation specifically indicates compatibility with 5V CMOS inputs, allowing direct interfacing with legacy 5V logic systems without additional level shifting circuitry.

Replacement Considerations

Direct substitutes include SN74AHCT1G32DBVR and SN74AHCT1G32DRLR. Verify that replacement parts maintain the same SOT-5 package outline and electrical parameters. Ensure the alternative part number includes the necessary environmental compliance markings such as G4 for lead-free status.
