74AHC1G32W5-7

Overview

The 74AHC1G32W5-7 is a single 2-input positive OR gate from the 74AHC logic family, manufactured by Diodes Incorporated. It operates within a supply voltage range of 2.0V to 5.5V and features standard push-pull outputs capable of ±8 mA drive current at 5.0V. The device utilizes Schmitt trigger inputs for tolerance to slower rise and fall times. Propagation delay ranges from 0.6 ns to 14.5 ns depending on load capacitance (15pF or 50pF) and operating temperature (-40°C to +125°C). It is housed in an SOT-25 surface-mount package.

Feature Summary

• Schmitt trigger action at all inputs provides circuit tolerance for slower input rise and fall times.
• ESD protection exceeds 200-V Machine Model, 2000-V Human Body Model, and 1000-V Charged Device Model standards.
• Latch-up performance exceeds 100mA per JESD 78, Class II specifications.
• Assembled with green molding compound containing no bromine or antimony.

Applications

• General purpose logic
• PCs, networking equipment, notebooks, netbooks, and PDAs
• Computer peripherals, hard drives, and CD/DVD ROM drives
• TV, DVD, DVR, set-top boxes, cell phones, and GPS devices

Procurement Notes

Verify that the ordering suffix W5 corresponds specifically to the SOT-25 package variant. Confirm the -7 suffix indicates tape and reel packaging with a quantity of 3000 units. Ensure compliance with RoHS directives and check for applicable exemptions before procurement.

Selection Notes

Select this component when a single 2-input OR function is required in space-constrained designs using the SOT-25 footprint. It is suitable for applications requiring operation across a wide voltage range from 2.0V to 5.5V. Consider the Schmitt trigger inputs if signal integrity requires noise immunity against slow transitions.

Part Context

This part belongs to the 74AHC1G series of single-gate logic ICs produced by Diodes Incorporated. The 'AHC' designation indicates high-speed CMOS technology optimized for low power consumption while maintaining fast switching speeds. The '1G' prefix specifies that the package contains only one independent logic gate.

Replacement Considerations

The 74AHC1G32SE-7 serves as a functional equivalent utilizing the SOT-353 package instead of SOT-25. Verify pin compatibility and physical dimensions before substituting packages within the same logic family.
