74AHC1G02SE-7

Overview

The 74AHC1G02SE-7 is a single 2-input positive NOR gate manufactured by Diodes Incorporated. It operates within a supply voltage range of 2.0V to 5.5V and features standard push-pull outputs with ±8 mA drive capability at 5.0V. The device utilizes CMOS technology for low power consumption and includes Schmitt trigger action at all inputs to tolerate slower input rise and fall times. Propagation delay ranges from 0.6 ns to 14.5 ns depending on load capacitance and temperature. It is housed in a SOT353 package.

Feature Summary

• Schmitt trigger inputs provide 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 requirements

Applications

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

Procurement Notes

Verify the specific ordering suffix SE corresponds to the SOT353 package configuration required for your design. Confirm that the -7 suffix aligns with tape and reel packaging quantities of 3000 units if bulk handling is necessary. Ensure compliance with RoHS directives and lead-free finish specifications during component sourcing. Cross-reference the manufacturer part number DS35170 Rev. 1-2 datasheet for any recent updates or revisions before finalizing procurement orders.

Selection Notes

Select this component when a compact single NOR gate solution is needed for 2.0V to 5.5V logic systems. The inclusion of Schmitt triggers makes it suitable for noisy environments or applications with slow signal transitions. Consider the SOT353 package size constraints and thermal resistance characteristics relative to your PCB layout. Verify that the ±8 mA output drive current meets the fan-out requirements of your downstream logic gates.

Part Context

This component belongs to the 74AHC1G series of high-speed CMOS logic gates produced by Diodes Incorporated. It serves as a single-function gate alternative to larger multi-gate packages, saving board space in dense designs. The AHC series offers performance comparable to older logic families while operating at lower voltages. This specific NOR gate variant provides essential Boolean logic functionality for digital signal processing and control applications.

Replacement Considerations

The 74AHC1G02W5-7 is a confirmed substitute offering identical logical function but packaged in SOT25 instead of SOT353. Verify pin compatibility and physical footprint differences before swapping packages. Other family members like the 74AHCT1G02QSE-7 operate at different voltage thresholds (4.5V minimum) and are not direct replacements for 2.0V operation scenarios.
