74AHCT1G32DCKRE4

Overview

The SN74AHCT1G32DCKRE4 is a single 2-input positive-OR gate from Texas Instruments, belonging to the AHCT logic series. It operates within a supply voltage range of 2.0 V to 5.5 V and features an SC-70-5 surface-mount package. The device provides symmetrical output drive currents of 8 mA for both high and low states. Propagation delay is specified at 6.5 ns under standard conditions. It supports an extended industrial temperature range from -40°C to +125°C.

Feature Summary

• Implements a single 2-input positive-OR logic function
• Compatible with CMOS outputs using TTL-compatible input thresholds
• Supports wide supply voltage operation from 2.0 V to 5.5 V

Applications

• Signal routing in mixed-voltage digital systems
• Logic combination in portable battery-powered devices
• General-purpose OR operations in embedded control circuits

Procurement Notes

Verify the complete part number including suffixes such as RE4 against official manufacturer documentation to ensure correct packaging and tape-and-reel specifications. Confirm RoHS compliance status and moisture sensitivity level requirements prior to procurement. Cross-reference ordering information directly with Texas Instruments to avoid discrepancies in component variants.

Selection Notes

Select this component when TTL-compatible inputs are required alongside CMOS performance levels. The AHCT series bridges the gap between older TTL logic families and modern CMOS technologies. Ensure the operating voltage aligns with the 2.0 V to 5.5 V specification. Consider the SC-70-5 package constraints for PCB layout and thermal management during selection.

Part Context

This device is part of the SN74AHCT1Gxx family of single-function gates designed for compact applications. The AHCT series specifically targets systems requiring interface between 5-V CMOS devices and 5-V TTL loads. The 1G32 designation identifies the specific OR gate function within this standardized logic portfolio.
