PI74STX1G14CX

Overview

The PI74STX1G14CX is a single Schmitt-trigger inverter from the STX series, manufactured by Diodes Incorporated using advanced submicron technology. It operates within a broad supply voltage range of 1.65V to 5.5V and features high-speed performance with a typical propagation delay of 2.7ns into 50pF at 5V VCC. The device provides high output drive capability of -24mA at 3V VCC and includes power-down high-impedance inputs/outputs. It is available in space-saving 5-pin SOT23 and SC70 packages.

Feature Summary

• Schmitt-trigger input action for noise immunity
• Broad operating voltage range from 1.65V to 5.5V
• High output drive strength of -24mA at 3V VCC
• Power-down high-impedance state for inputs and outputs

Applications

• Signal conditioning and waveform shaping
• Oscillator circuits requiring hysteresis
• Pulse generation and timing applications
• Level shifting between different logic families

Procurement Notes

Verify the specific package suffix (C for SC70 or T for SOT23) against your PCB footprint requirements. Confirm RoHS compliance status as datasheets may vary by revision. Check for obsolescence notices or PCNs before finalizing designs. Ensure unused inputs are tied to valid logic levels to prevent floating states.

Selection Notes

Select this component when hysteresis is required to clean up noisy digital signals. The wide voltage compatibility allows integration across mixed-voltage systems. Consider the small form factor of the SC70 package for dense layouts. Verify that the propagation delay meets the system's timing constraints under expected load conditions.

Part Context

This part belongs to the Pericom STX series of logic gates, now produced under Diodes Incorporated following acquisition. The STX line utilizes submicron CMOS technology to deliver high speed and low power consumption in compact packages. It serves as a fundamental building block for digital logic design requiring signal inversion with noise rejection capabilities.

Replacement Considerations

Direct pin-compatible replacements include other single Schmitt-trigger inverters in SOT23-5 or SC70-5 packages such as the SN74LVC1G14 or CD74HC14 variants, provided voltage levels and drive currents match application needs.
