74AHC1G32SE-7

Overview

The 74AHC1G32SE-7 is a single 2-input positive OR gate from Diodes Incorporated, part of the 74AHC logic family. It operates within a supply voltage range of 2.0V to 5.5V and features Schmitt trigger inputs for noise tolerance. The device provides ±8 mA output drive at 5.0V and includes ESD protection exceeding 2000-V Human Body Model standards. Packaged in SOT-353 (SC-70-5), it supports an operating temperature range of -40°C to +125°C with propagation delays as low as 4.6 ns at 5V.

Feature Summary

• Schmitt trigger action at all inputs ensures circuit tolerance for slower input rise and fall times.
• ESD protection exceeds 2000-V Human Body Model, 200-V Machine Model, and 1000-V Charged Device Model per JESD 22.
• Latch-up performance exceeds 100mA per JESD 78, Class II.
• Assembled with green molding compound free of bromine and antimony.

Applications

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

Procurement Notes

Verify the specific package suffix SE corresponds to the SOT-353 footprint required for your design. Confirm that the RoHS compliance status meets your project's environmental regulations. Ensure the operating temperature range of -40°C to +125°C aligns with your system's thermal requirements. Check for any specific handling instructions related to the tape and reel packaging format.

Selection Notes

Select this component when a compact, single-channel OR gate is needed for high-speed digital logic applications. The AHC series offers CMOS low power consumption while maintaining fast switching speeds. Consider the SOT-353 package for space-constrained PCB layouts. Verify input voltage levels against the specified VIH and VIL thresholds for your chosen supply voltage.

Part Context

This device belongs to the 74AHC1G series of single-gate logic ICs manufactured by Diodes Incorporated. It implements the standard Boolean OR function using push-pull outputs. The 74AHC family is designed for high-speed operation with wide supply voltage compatibility, making it suitable for modern digital systems requiring efficient signal processing in minimal footprints.

Replacement Considerations

The 74AHC1G32SE-7 can be replaced by other manufacturers' equivalents such as SN74AHC1G32DCKR from Texas Instruments or 74AHCT1G32GW,125 from Nexperia, provided pinout and electrical characteristics match. Note that AHCT variants may have different input voltage thresholds compared to the AHC series.
