74AUP2G3404FW4-7

Overview

The 74AUP2G3404FW4-7 is a dual-gate CMOS logic device from Diodes Incorporated, featuring one non-inverting buffer and one inverter. It operates within a supply voltage range of 0.8V to 3.6V and utilizes push-pull outputs capable of ±4mA drive at 3.0V. The component incorporates Schmitt trigger inputs for noise tolerance and includes I_OFF circuitry to prevent backflow during partial power-down states. Packaged in an X2-DFN1010-6 surface-mount format, it supports operation across temperatures from -40°C to +125°C.

Feature Summary

• Integrates one buffer and one inverter with push-pull outputs for versatile signal routing.
• Schmitt trigger inputs provide enhanced noise immunity against slow input transitions.
• I_OFF circuitry enables safe partial power-down mode by disabling outputs to prevent current backflow.
• Advanced Ultra Low Power (AUP) CMOS technology ensures low static and dynamic power consumption.

Applications

• Portable computing devices such as notebooks, netbooks, and tablet computers
• Consumer electronics including cell phones, MP3 players, and digital cameras
• Computer peripherals like hard drives and CD/DVD ROMs
• Set-top boxes, DVRs, and television systems

Procurement Notes

Verify the specific package code FW4 corresponds to the X2-DFN1010-6 footprint before procurement. Confirm that the ordering suffix matches the required tape and reel quantity. Ensure compatibility with RoHS and halogen-free manufacturing standards if applicable to your assembly process. Cross-reference pin assignments with your PCB layout to ensure correct orientation.

Selection Notes

Select this component when a mixed buffer and inverter configuration is required in a minimal footprint. It is suitable for applications demanding low power consumption alongside robust noise immunity provided by Schmitt triggers. Consider this part for portable designs where partial power-down functionality is necessary to extend battery life without compromising signal integrity.

Part Context

This device belongs to the 74AUP2G series of Advanced Ultra Low Power logic ICs. It shares the AUP family's characteristics of extended battery life and wide operating voltage ranges. The FW4 suffix specifically denotes the X2-DFN1010-6 leadless package variant, distinguishing it from other package options like FZ4 or FW3 within the same logical function family.

Replacement Considerations

Check datasheets for alternative packages such as 74AUP2G3404FZ4-7 or 74AUP2G3404FW3-7 for physical footprint differences. Verify functional equivalence with other single-supply buffer/inverter combinations if pinout variations exist.

FAQ

How does the I_OFF feature benefit system design?

The I_OFF circuitry disables the outputs when the device is powered down, preventing damaging current backflow into the supply rail from downstream components.

What is the purpose of the Schmitt trigger inputs?

Schmitt trigger action provides hysteresis, making the circuit tolerant of slower input rise and fall times and improving noise immunity.
