SN74AHC1G32DRLRG4

Overview

The SN74AHC1G32DRLRG4 is a single 2-input positive-OR gate from the Texas Instruments 74AHC series. It operates within a supply voltage range of 2V to 5.5V and features low static current consumption of 1 µA maximum. The device utilizes SOT-553 surface-mount packaging with five terminals. It supports logic high levels from 1.5V to 3.85V and logic low levels from 0.5V to 1.65V. Maximum output drive capability is specified at 8mA for both high and low states. Propagation delay reaches 7.5ns at 5V with 50pF load capacitance.

Feature Summary

• Single-channel architecture providing one independent 2-input OR logic function
• Compatible with CMOS outputs for interfacing with standard digital systems
• RoHS compliant construction supporting lead-free manufacturing standards

Applications

• General-purpose digital signal processing circuits
• Portable battery-operated electronic devices
• Consumer electronics requiring low power consumption

Procurement Notes

Verify the complete part number including the G4 suffix to confirm RoHS compliance and lead-free status. Ensure the ordering code matches the specific SOT-553 tape and reel configuration required for automated assembly processes. Cross-reference manufacturer documentation for updated moisture sensitivity levels before procurement.

Selection Notes

Select this component when a compact single-gate solution is required for space-constrained designs. The AHC series offers faster switching speeds compared to standard HC logic while maintaining compatibility. Verify that the operating voltage range aligns with the system power rails and that the package footprint fits the PCB layout constraints.

Part Context

This integrated circuit belongs to the broader 74AHC family of high-speed CMOS logic devices manufactured by Texas Instruments. The family provides performance improvements over previous generations while maintaining pinout compatibility with industry-standard logic families. The DRLR variant specifically denotes the SOT-553 surface-mount package configuration optimized for high-density board layouts.

Replacement Considerations

Direct functional equivalents include the SN74AHC1G32DRLR without the environmental suffix. Other single OR gates in the same package, such as those from the LVC or HCT series, may serve as alternatives if voltage levels or speed requirements differ.
