PI74ST1G32TEX

Overview

The PI74ST1G32TEX is a single 2-input OR gate from the SOTiny Gate ST series, manufactured by Diodes Incorporated. It operates within a supply voltage range of 1.8V to 3.6V and supports an input voltage up to 5.5V. The device features a typical propagation delay of 1.8ns at 1.8V and provides high output drive capability of ±24mA at 3V. It is available in 5-pin SOT-23 and SC-70 packages.

Feature Summary

• High-speed logic operation with low propagation delay
• Broad operating voltage range for flexible system integration
• Power-down protection maintains high-impedance inputs and outputs
• High output drive strength suitable for demanding loads

Applications

• Portable consumer electronics requiring low power consumption
• Battery-operated devices utilizing 1.8V to 3.6V power rails
• Mixed-voltage signal interfacing applications
• Space-constrained circuit board designs

Procurement Notes

Verify that the ordering suffix 'TEX' corresponds to the specific tape and reel packaging configuration required for automated assembly processes. Confirm that the component meets lead-free and green material specifications as indicated by the 'E' designation in standard part numbers. Ensure compatibility with surface mount mounting methods for both SOT-23 and SC-70 package variants during procurement planning.

Selection Notes

Select this component when a compact 2-input OR function is needed within a 1.8V to 3.6V supply environment. The device is appropriate for designs requiring high output current drive capabilities without increasing package size. Consider the 5.5V tolerant inputs if interfacing with higher voltage logic levels while maintaining a lower core supply voltage.

Part Context

This component belongs to the SOTiny Gate ST family, which focuses on providing standard logic functions in ultra-small footprints. The series is designed to support modern portable electronics where space and power efficiency are critical constraints. It complements other gates and inverters within the same product line offering similar performance characteristics.

Replacement Considerations

The PI74ST1G32TEC serves as a lead-free alternative to the standard version. Verify pinout compatibility and electrical specifications before substituting with other single 2-input OR gates from different manufacturers.
