Overview
The SN74AHC1G32DBVRG4 is a single-channel, dual-input positive OR gate from the Texas Instruments SN74AHC1G series. It operates within a supply voltage range of 2V to 5.5V and features push-pull outputs with a maximum drive current of 8mA for both high and low states. The device exhibits a typical propagation delay of 6.5ns at 5V with a 50pF load. It supports an operating temperature range from -40°C to +125°C and is housed in a SOT-23-5 surface-mount package.
Feature Summary
- Single-channel architecture providing one independent two-input OR logic function
- Advanced High-Speed CMOS technology enabling operation across a wide 2V to 5.5V supply range
- Push-pull output stage designed for robust signal driving capabilities
- Extended industrial temperature rating supporting reliable performance in harsh environments
Applications
- General-purpose digital logic signal routing

- Industrial control system logic interfaces
- Consumer electronics signal processing circuits
Procurement Notes
Verify the complete part number including the G4 suffix to confirm RoHS compliance status. Ensure the ordering code matches the specific SOT-23-5 tape and reel configuration required for automated assembly processes. Cross-reference the manufacturer's latest datasheet revision to confirm pinout consistency and electrical characteristics before finalizing procurement specifications.
Selection Notes
Select this component when a compact, single-gate solution is required for space-constrained designs. The AHC series offers superior speed compared to standard HC logic while maintaining low power consumption suitable for battery-operated applications. Verify that the 8mA drive strength meets the input requirements of downstream loads without necessitating additional buffering stages.
Part Context
This device belongs to the SN74AHC1G family of ultra-small single-gate logic ICs. These components are engineered to replace larger discrete logic solutions in modern PCB layouts. The family shares common electrical characteristics but varies by packaging options such as SC-70-5 and SOT-553 to accommodate diverse board space limitations.
Replacement Considerations
The SN74AHC1G32DBVR serves as the base commercial variant. The SN74AHC1G32DCKR provides equivalent functionality in an SC-70-5 package. Substitution requires verification of package footprint compatibility and confirmation that the replacement part meets the same voltage and temperature specifications.
