Overview
The SN74AHCT1G32DCKT is a single 2-input positive-OR gate from the Texas Instruments 74AHCT logic family. It operates within a supply voltage range of 4.5 V to 5.5 V and features a SC-70-5 surface-mount package. The device provides an output current capability of 8 mA for both high and low states, with a maximum propagation delay of 7.9 ns at 5 V with a 50 pF load. It supports industrial operating temperatures from -40°C to +125°C.
Feature Summary
- Implements single-channel two-input OR logic functionality
- Compatible with standard 5 V CMOS logic levels via AHCT series design
- Utilizes compact SC-70-5 surface-mount packaging
Applications
- Digital signal processing circuits requiring OR logic operations
- Embedded systems utilizing 5 V logic interfaces
- Industrial control modules operating in extended temperature ranges
Procurement Notes
Verify that the specific part number SN74AHCT1G32DCKT matches the required AHCT logic family and 5 V operation parameters. Confirm the SC-70-5 package type aligns with PCB footprint requirements. Ensure the industrial temperature rating meets environmental specifications. Cross-reference official datasheets to validate pinout and electrical characteristics against system constraints.
Selection Notes
Select this component when 5 V CMOS compatibility is required for OR logic functions. The AHCT series ensures direct interface with TTL-level inputs while maintaining CMOS performance. Consider the SC-70-5 package for space-constrained designs. Verify that the 8 mA drive strength and 7.9 ns delay meet timing requirements for the target application frequency.
Part Context
This component belongs to the Texas Instruments 74AHCT1G32 series of single-function gates. The series offers optimized performance for 5 V applications, bridging the gap between older TTL standards and modern CMOS technologies. The specific DCKT suffix indicates the SC-70-5 tape-and-reel packaging format suitable for automated surface-mount assembly processes.
Replacement Considerations
SN74AHCT1G32DBVR: Alternative SC-70-5 packaged version from the same manufacturer. SN74AHC1G32DCKR: Similar AHC series variant with wider voltage range but different input threshold characteristics.
