74LVT14D,112

Inverter Gates Overview

The Nexperia 74LVT14D,112 is a hex inverter with Schmitt-trigger inputs housed in a 14-lead SO plastic small outline package (SOT108-1). It operates within a supply voltage range of 2.7 V to 3.6 V and features overvoltage tolerant inputs up to 5.5 V. The device provides an output capability of +32 mA/-20 mA and includes IOFF circuitry for partial power-down applications. It complies with JEDEC standard JESD8C and supports operation from -40 °C to +85 °C.

Inverter Gates Feature Summary

• Schmitt-trigger action eliminates the need for external pull-up resistors on unused inputs via bus hold data inputs.
• IOFF circuitry disables outputs during partial power-down to prevent potentially damaging backflow current.
• BiCMOS technology ensures high speed and robust output drive capabilities.
• Direct interface compatibility with TTL levels without bus current loading when tied to a 5 V bus.

Inverter Gates Applications

• Signal conditioning for slowly changing input transitions
• Partial power-down mode operations requiring backflow prevention
• Interfaces between 3.3 V logic systems and 5 V buses

Inverter Gates Procurement Notes

Verify the specific ordering suffix '112' corresponds to the tube packaging format required for your assembly line. Confirm that the SO14 package variant matches your PCB footprint specifications. Ensure design compliance with the specified operating temperature range and absolute maximum ratings to maintain device reliability.

Inverter Gates Selection Notes

Select this component when designing circuits requiring noise immunity against slow signal transitions or where direct interfacing with TTL logic levels is necessary. The inclusion of bus hold inputs simplifies board layout by removing the requirement for external pull-up components on unconnected pins.

Inverter Gates Part Context

This part belongs to the 74LVT series of low-voltage CMOS logic devices manufactured by Nexperia. It is specifically designed for 3.3 V applications while maintaining compatibility with legacy 5 V systems through its overvoltage tolerant inputs and TTL-compatible thresholds.

Inverter Gates Replacement Considerations

Public confirmed substitute part numbers include 74LVT14PW,118 and 74LVT14BQ,118.

Inverter Gates FAQ

How does the device handle unused inputs?

Bus hold data inputs eliminate the need for external pull-up resistors to define unused inputs.

What is the function of the IOFF circuitry?

The IOFF circuitry disables the output to prevent potentially damaging backflow current through the device when it is powered down.
