74AHCT1G32DBVRG4

Overview

The SN74AHCT1G32DBVRG4 is a single 2-input positive-OR gate from Texas Instruments, part of the AHCT logic family. It operates within a supply voltage range of 4.5 V to 5.5 V and features a propagation delay of 7.5 ns at 5 V. The device provides an output current capability of 8 mA for both high and low states. It is housed in a SOT-23-5 package and supports an operating temperature range from -40 °C to +125 °C.

Feature Summary

• Single-channel 2-input positive-OR logic function
• Compatible with CMOS outputs and TTL inputs via AHCT technology
• High noise immunity with defined switching thresholds
• Compact surface-mount SOT-23-5 packaging

Applications

• Digital signal routing in 5V logic systems
• Combining multiple control signals into a single line
• Interface circuits between CMOS and TTL components

Procurement Notes

Verify the complete ordering code including the G4 suffix to ensure compliance with RoHS directives and lead-free manufacturing standards. Confirm that the SOT-23-5 package variant matches your PCB footprint requirements. Ensure static-sensitive handling procedures are followed during assembly to prevent ESD damage to the internal circuitry.

Selection Notes

Select this component when a single OR gate is required in a strict 5V environment. The AHCT series ensures compatibility with legacy TTL input levels while maintaining CMOS performance. Consider the SOT-23-5 package size constraints and the specific 7.5 ns propagation delay against system timing requirements before finalizing the design.

Part Context

This device belongs to the SN74AHCT1Gxx series of single-gate logic ICs. It shares the same logical function as the SN74LVC1G32 but differs in voltage tolerance and input threshold characteristics. The AHCT family is specifically engineered for mixed-voltage applications requiring robust interfacing between different logic families.

Replacement Considerations

The SN74AHCT1G32DRVTG4 is a confirmed pin-compatible alternative in the same SOT-23-5 package. Verify electrical specifications match if substituting with other single OR gates.
