74AHCT1G02W5-7

Overview

The 74AHCT1G02W5-7 is a single 2-input positive NOR gate from the AHCT logic family, manufactured by Diodes Incorporated. It operates within a supply voltage range of 4.5V to 5.5V and features Schmitt trigger inputs for tolerance to slower input rise and fall times. The device provides ±8 mA output drive at 5.0V and includes ESD protection exceeding 2000-V Human Body Model standards. It utilizes a SOT25 package with five pins.

Feature Summary

• Features Schmitt trigger action at all inputs to ensure circuit tolerance for slower input rise and fall times.
• Provides standard totem pole output with an output drive capability of ±8 mA at 5.0V.
• Includes robust ESD protection that exceeds 200-V Machine Model and 2000-V Human Body Model ratings.

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 the specific ordering suffix W5 corresponds to the SOT25 package configuration required for your design. Confirm that the -7 suffix indicates tape and reel packaging containing 3000 units per reel. Ensure compatibility with the specified 4.5V to 5.5V operating voltage range and check RoHS compliance status before finalizing procurement orders.

Selection Notes

Select this component when a single 2-input NOR function is required in a compact surface-mount footprint. The AHCT series ensures TTL-compatible input levels while maintaining CMOS low power consumption characteristics. Verify that the SOT25 package dimensions align with your PCB layout constraints and that the operating temperature range meets your environmental requirements.

Part Context

This part belongs to the 74AHCT1G series of single-gate logic ICs designed for high-speed digital applications. The AHCT family bridges the gap between older TTL logic families and modern CMOS technologies by providing compatible input thresholds. Diodes Incorporated manufactures this component using lead-free finish processes compliant with EU Directive 2002/95/EC (RoHS).

Replacement Considerations

The 74AHCT1G02SE-7 serves as a direct functional replacement utilizing the SOT353 package instead of SOT25. Other manufacturers producing JEDEC-compliant 74AHCT1G02 devices may offer equivalent electrical performance, though pinout and package dimensions must be verified for mechanical interchangeability.

FAQ

What is the Boolean function performed by the 74AHCT1G02?

The device performs the positive Boolean function Y = A + B, which represents a 2-input NOR gate operation.

How does the device handle slow input transitions?

Schmitt trigger action at all inputs makes the circuit tolerant for slower input rise and fall times, preventing erratic switching behavior.

What are the ESD protection ratings for this component?

The device exceeds 200-V Machine Model (A115-A), 2000-V Human Body Model (A114-A), and 1000-V Charged Device Model (C101C) ratings per JESD 22.
