SN74AHC1G32DBVT

Overview

The SN74AHC1G32DBVT is a single 2-input positive-OR gate from the Texas Instruments SN74AHC1G series. It operates within a supply voltage range of 2 V to 5.5 V and features an SC-70-5 (SOT-5) surface-mount package. The device supports a wide operating temperature range from -40°C to +125°C, ensuring reliability in demanding environments. Key electrical characteristics include a maximum propagation delay of 6.5 ns at 5 V with a 50 pF load, and symmetrical output drive capabilities of 8 mA for both high and low states.

Feature Summary

• Single-channel architecture providing one independent 2-input OR logic function
• Advanced High-Speed CMOS technology enabling operation across a broad 2 V to 5.5 V supply range
• Industrial-grade thermal stability supporting continuous operation from -40°C to +125°C
• Compact SC-70-5 footprint designed for space-constrained printed circuit board layouts

Applications

• Digital signal routing and selection circuits
• Microcontroller peripheral interface logic
• Battery-powered portable electronic devices
• Automotive infotainment system logic gates

Procurement Notes

Verify the complete part number including the 'T' suffix to confirm tape-and-reel packaging specifications. Ensure compatibility with standard SC-70-5 footprints during PCB layout. Confirm RoHS compliance status through official manufacturer documentation prior to integration into regulated assemblies.

Selection Notes

Select this component when a compact, high-speed OR gate is required for systems operating between 2 V and 5.5 V. The AHC series offers superior speed compared to standard HC logic while maintaining CMOS power efficiency. Verify that the 8 mA output current meets the driving requirements of downstream loads without exceeding absolute maximum ratings.

Part Context

This device belongs to the SN74AHC1G family of single-gate integrated circuits. These components are engineered to replace older discrete logic solutions in modern miniaturized designs. The AHC series bridges the performance gap between standard 74HC and advanced 74AHCT technologies, offering faster switching speeds and lower noise margins suitable for high-density digital applications.

Replacement Considerations

SN74AHC1G32DBVR: Identical logical function and pinout; differs only in reel packaging format rather than cut-tape delivery.
