74AHCT1G32W5-7

Overview

The 74AHCT1G32W5-7 is a single 2-input positive OR gate from the 74AHCT logic family, manufactured by Diodes Incorporated. It operates within a supply voltage range of 4.5V to 5.5V and features Schmitt trigger action at all inputs for tolerance to slower input rise and fall times. The device provides ±8 mA output drive capability at 5.0 V and includes ESD protection exceeding 200-V Machine Model, 2000-V Human Body Model, and 1000-V Charged Device Model standards. It is housed in an SOT-25 package with lead-free finish and RoHS compliance.

Feature Summary

• Single 2-input positive OR gate with standard totem pole output
• Schmitt trigger action at all inputs for improved noise immunity
• High ESD protection ratings across multiple testing models
• CMOS low power consumption design

Applications

• General purpose logic circuits
• PCs, networking equipment, notebooks, and netbooks
• Computer peripherals, hard drives, and CD/DVD ROM drives
• TV, DVD, DVR, and set-top boxes
• Phones, personal navigation/GPS devices, MP3 players, cameras, and video recorders

Procurement Notes

Verify that the component matches the exact part number 74AHCT1G32W5-7, specifically confirming the W5 suffix indicates the SOT-25 package type. Ensure the ordering suffix -7 corresponds to the Tape & Reel packaging format as specified in the manufacturer's documentation. Confirm compliance with RoHS directives and check for any specific environmental or handling requirements associated with the green molding compound used in assembly.

Selection Notes

Select this component when a single 2-input OR function is required in compact surface-mount designs. The AHCT series ensures TTL-compatible input levels while maintaining CMOS performance characteristics. Consider the SOT-25 package for space-constrained applications where a larger footprint is not feasible. Verify that the operating temperature range of -40°C to +125°C meets the environmental demands of the target application.

Part Context

This device belongs to the 74AHCT1Gxx series of single-gate logic ICs produced by Diodes Incorporated. The 'AHCT' designation signifies compatibility with 5V CMOS and TTL logic families, allowing seamless integration into mixed-voltage systems. The '1G' prefix denotes a single functional gate within a minimal footprint package, optimizing board space compared to traditional multi-gate configurations.

Replacement Considerations

Direct pin-to-pin replacements may include other manufacturers' 74AHCT1G32 variants in SOT-25 packages. Verify electrical specifications such as propagation delay and output current drive capabilities before substitution. Ensure that any alternative component maintains the same Schmitt trigger input characteristics and ESD protection levels to preserve circuit integrity.
