1P1G14MDBVREP

Overview

The SN74LVC1G14MDBVREP is a single Schmitt-trigger inverter from Texas Instruments, designed for operation within a supply voltage range of 1.65 V to 5.5 V. It features an SOT-23 (DBV) package with five pins and supports an operating temperature range from -55 °C to +125 °C. The device provides a maximum propagation delay of 4.6 ns at 3.3 V and offers output drive currents up to ±24 mA at 3.3 V. It includes Ioff circuitry to support partial-power-down mode, preventing damaging backflow current when the device is powered down.

Feature Summary

• Schmitt-trigger action provides distinct input threshold levels for positive-going and negative-going signals to improve noise immunity.
• Ioff circuitry disables outputs to prevent damaging current backflow during partial-power-down applications.
• ESD protection exceeds JESD 22 standards, including 2000-V Human-Body Model and 1000-V Charged-Device Model ratings.

Applications

• Partial-power-down mode circuits requiring output disabling upon power loss
• Signal conditioning where hysteresis improves noise immunity
• Single-channel logic inversion in low-voltage digital systems

Procurement Notes

Verify the exact part number against the manufacturer's official documentation to ensure compatibility with your specific design requirements. Confirm that the ordering suffix matches the intended package type and production status. Cross-reference the datasheet revision date to ensure all electrical characteristics and mechanical dimensions are current. Ensure compliance with RoHS directives and material declarations as specified in the product folder.

Selection Notes

Select this component when a single inverting gate with hysteresis is required in a compact surface-mount package. Consider the 1.65 V to 5.5 V supply range for compatibility with various logic families. Evaluate the propagation delay specifications against your system's timing constraints. Verify that the extended temperature range meets your environmental operating conditions.

Part Context

This component belongs to the SN74LVC1G14-EP family, which represents enhanced product versions of standard logic devices. These parts are designed for controlled baseline manufacturing with one assembly/test site and one fabrication site. They feature enhanced diminishing manufacturing sources support and enhanced product-change notification policies to ensure long-term availability.

Replacement Considerations
