74AUP1G32SE-7

Overview

The 74AUP1G32SE-7 is a single two-input positive OR gate from the Advanced Ultra Low Power (AUP) CMOS logic family. It operates within a supply voltage range of 0.8V to 3.6V and features standard push-pull outputs with ±4mA drive capability at 3.0V. The device includes Schmitt trigger action on all inputs for noise tolerance and supports partial power-down modes via I_OFF circuitry. It is housed in a SOT-353 package, suitable for surface mount applications.

Feature Summary

• Advanced Ultra Low Power (AUP) CMOS technology designed for extended battery life
• Schmitt trigger action at all inputs provides tolerance for slower rise and fall times
• I_OFF circuitry enables partial power-down mode operation by disabling outputs
• Totally lead-free and fully RoHS compliant with halogen and antimony free construction

Applications

• Tablets and E-readers
• Cell Phones and Personal Navigation/GPS devices
• MP3 Players, Cameras, and Video Recorders
• PCs, Ultrabooks, Notebooks, and Netbooks
• Computer Peripherals including Hard Drives, SSDs, and CD/DVD ROMs

Procurement Notes

Verify the specific ordering suffix matches the required package type, as the SE designation corresponds to the SOT-353 package. Confirm that the -7 suffix aligns with the desired tape and reel quantity of 3,000 units. Ensure compatibility with the target operating temperature range of -40°C to +125°C during component selection.

Selection Notes

Select this component when low static power consumption is critical, specifically where supply current must remain below 0.9µA. The inclusion of Schmitt triggers makes it suitable for environments with noisy signals or slow input transitions. Verify that the 0.8V minimum supply voltage meets the lowest system rail requirements.

Part Context

This part belongs to the 74AUP1G series, which utilizes AUP CMOS technology to achieve ultra-low power dissipation compared to standard logic families. The 74AUP1G32 specifically implements a single OR function within a compact footprint, serving as a fundamental building block for digital logic circuits requiring minimal energy usage.

Replacement Considerations

Check datasheets for other manufacturers offering equivalent AUP series OR gates. Verify pinout compatibility and electrical characteristics such as propagation delay and output drive strength before substitution.

FAQ

How does the I_OFF feature benefit the 74AUP1G32SE-7?

The I_OFF circuitry disables the output when the device is powered down, preventing potentially damaging backflow current through the device.

What is the purpose of the Schmitt trigger action in this gate?

The Schmitt trigger action at all inputs makes the circuit tolerant of slower input rise and fall times, improving noise immunity.
