PI74STX1GU04TEX

Overview

The PI74STX1GU04TEX is an unbuffered inverter from the SOTiny Gate STX series, manufactured by Diodes Incorporated. It operates within a supply voltage range of 1.65V to 5.5V and supports an operating temperature range of -40°C to 85°C. The device features a typical propagation delay of 2.6ns into 50pF at 5V VDD. It provides balanced output drive capabilities of ±8mA at 3V VDD and includes power-down high-impedance inputs/outputs. The component is available in a 5-pin SOT23 package.

Feature Summary

• Unbuffered inverter logic function with high-speed performance
• Broad operating voltage range supporting low-power applications
• Power-down high-impedance state for inputs and outputs
• Balanced output drive capability

Applications

• General digital signal inversion
• Low-voltage logic interface circuits
• Portable electronic devices requiring small form factor components

Procurement Notes

Verify that the ordering suffix TEX corresponds to the specific tape and reel packaging configuration required for automated assembly processes. Confirm the package type matches the design footprint, as the base part number is available in multiple physical packages including SOT23, SC70, and UDFN. Ensure compliance with RoHS and Green material specifications if environmental regulations apply to the final product assembly.

Selection Notes

Select this component when a single-channel inverter is required in a minimal footprint. The STX series offers high speed relative to its size. Consider the unbuffered output characteristic, which may require careful load management in linear region operation. Verify input handling requirements, as unused inputs must not float and should be held to a defined logic level to ensure reliable operation.

Part Context

This component belongs to the Pericom Semiconductor Corporation portfolio, now part of Diodes Incorporated. The PI74STX1GU04 is part of the SOTiny Gate STX family, designed for space-constrained applications. The 'TEX' designation indicates the specific orderable version with Tape & Reel packaging and Pb-free/Green compliance.

Replacement Considerations

Direct substitutes include other variants of the PI74STX1GU04 family such as the PI74STX1GU04CEX (SC70 package) or PI74STX1GU04ZREX (UDFN package), provided the physical footprint allows. Cross-brand replacements require matching voltage ranges, propagation delays, and package dimensions.
