74AHCT1G32SE-7

Overview

The 74AHCT1G32SE-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 a standard totem pole output capable of ±8 mA drive current at 5.0 V. The device incorporates Schmitt trigger action on all inputs to tolerate slower input rise and fall times. It is housed in an SOT-353 package and supports an operating free-air temperature range from -40°C to +125°C.

Feature Summary

• Provides Boolean OR function with standard totem pole output structure
• Incorporates Schmitt trigger inputs for tolerance against slow signal transitions
• Offers robust ESD protection exceeding specified thresholds for machine, human body, and charged device models
• Constructed using CMOS technology for low power consumption

Applications

• General purpose logic circuits
• PCs, networking equipment, notebooks, and netbooks
• Computer peripherals including hard drives and CD/DVD ROMs
• 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 specific SE suffix indicating the SOT-353 package configuration. Confirm the AHCT designation aligns with required TTL-compatible input levels. Ensure the application environment remains within the specified 4.5V to 5.5V supply voltage limits. Validate thermal management requirements against the junction-to-ambient resistance values provided in the datasheet.

Selection Notes

Select this component when a single 2-input OR gate is required with TTL-compatible logic levels. The AHCT series ensures compatibility with standard 5V TTL systems while utilizing CMOS technology. Consider the SOT-353 package for space-constrained surface-mount designs. Verify that the operating temperature range meets the environmental demands of the target application.

Part Context

This part belongs to the 74AHCT1Gxx series of single-function gates produced by Diodes Incorporated. The '1G' designation indicates a single gate per package, while '32' identifies the OR logic function. The 'SE' suffix specifies the SOT-353 (SC-70-5) surface-mount package. The '-7' suffix denotes tape and reel packaging for automated assembly processes.
