74AHCT1G04W5-7

Overview

The 74AHCT1G04W5-7 is a single inverter 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 5.0V. The device incorporates Schmitt trigger action on all inputs to tolerate slower input rise and fall times. It is housed in an SOT-25 package with five pins: NC, A (Input), GND, Y (Output), and VCC. Propagation delay ranges from 0.6ns to 10.05ns depending on load capacitance and temperature.

Feature Summary

• Schmitt trigger inputs provide circuit tolerance for slower input rise and fall times.
• Standard totem pole output delivers ±8 mA drive capability at 5.0V.
• ESD protection exceeds 200-V Machine Model, 2000-V Human Body Model, and 1000-V Charged Device Model standards.

Applications

• General purpose logic applications
• 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 W5 suffix indicating the SOT-25 package configuration. Confirm the -7 packaging designation corresponds to tape and reel quantities as specified in the ordering information. Ensure compliance with RoHS directives and lead-free finish requirements stated in the datasheet notes. Cross-reference the document number DS35181 Rev. 1-2 to ensure the latest revision is obtained.

Selection Notes

Select this component when TTL-compatible input levels are required alongside CMOS low power consumption characteristics. The AHCT series ensures compatibility with 5V TTL systems while maintaining low static power dissipation. Consider the Schmitt trigger feature if the application involves noisy environments or signals with slow transition rates. Verify that the operating temperature range of -40°C to 125°C meets the environmental requirements of the target system.

Part Context

This part belongs to the 74AHCT1Gxx series of single-gate logic ICs produced by Diodes Incorporated under the DiodesZetex brand. The 'AHCT' designation indicates high-speed CMOS technology compatible with TTL input levels up to 5.5V. The '1G' prefix signifies a single gate per package, optimizing board space for compact designs requiring minimal logic functions in portable electronics.

Replacement Considerations

No public confirmed substitute part numbers are provided in the source material.

FAQ

What is the function of the NC pin on the 74AHCT1G04W5-7?

Pin 1 is designated as No Connection (NC) and should not be electrically connected in the circuit design.

How does the Schmitt trigger action benefit the 74AHCT1G04?

It makes the circuit tolerant for slower input rise and fall times, ensuring stable switching even with gradual signal transitions.

What are the absolute maximum ratings for the supply voltage?

The absolute maximum rating for the supply voltage (VCC) is -0.5V to 6.5V, though recommended operation is between 4.5V and 5.5V.
