Overview
The SN74AHC1G32DCKRG4 is a single 2-input positive-OR gate from the Texas Instruments AHC series. It operates within a supply voltage range of 2 V to 5.5 V and supports an output current of 8 mA for both high and low states. The device features a maximum propagation delay of 7.5 ns at 5 V with a 50 pF load. It is housed in a compact SC-70-5 package and functions reliably across an extended temperature range of -40°C to 125°C.
Feature Summary
- Provides a single 2-input positive-OR logic function
- Operates on a wide supply voltage range from 2 V to 5.5 V
- Delivers 8 mA output drive capability
- Ensures reliable performance across an extended industrial temperature range
Applications
- Signal routing and selection circuits

- Portable battery-powered devices
Procurement Notes
Verify the complete part number including the G4 suffix, which indicates lead-free and RoHS compliance. Confirm the SC-70-5 package type matches the design footprint. Ensure the operating environment stays within the specified -40°C to 125°C range. Check datasheet specifications for static current limits and input voltage thresholds before finalizing procurement.
Selection Notes
Select this component when a single OR gate is required in a minimal footprint. The AHC series offers faster switching speeds compared to standard HC logic while maintaining CMOS power efficiency. The wide voltage range allows compatibility with various digital systems. Verify that the 8 mA drive current meets the load requirements of the connected circuitry.
Part Context
This component belongs to the SN74AHC1G32 family of single-gate logic ICs. It shares the same logical functionality as variants like the SN74AHC1G32DCKT but includes specific manufacturing and environmental certifications indicated by the suffix. The SC-70-5 package provides space-saving advantages for dense PCB layouts.
Replacement Considerations
Direct substitutes include SN74AHC1G32DCKT and SN74AHC1G32DCKR. These parts share identical electrical characteristics and pinouts. Verify package availability and specific ordering suffixes for environmental compliance when sourcing alternatives.
