74LVT14DB,112

Inverter Gates Overview

The Nexperia 74LVT14DB,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 an operating temperature range from -40 °C to +85 °C.

Inverter Gates Feature Summary

• Schmitt-trigger inputs provide tolerance for slow input transitions and different positive/negative going threshold voltages.
• IOFF circuitry disables outputs during partial power-down to prevent damaging backflow current.
• Bus hold data inputs eliminate the need for external pull-up resistors to define unused inputs.

Inverter Gates Applications

• Partial power-down mode operation
• Direct interface with TTL levels
• Signal inversion in 3.3 V logic systems

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 design. Ensure the component status is checked against current manufacturing schedules as product availability may change.

Inverter Gates Selection Notes

Select this component when a hex inverter with hysteresis is required for noisy environments or slow signals. The wide input voltage tolerance allows interfacing with 5 V buses without loading issues. Consider the 3-state power-up behavior if bus contention must be avoided during system initialization.

Inverter Gates Part Context

This part belongs to the 74LVT family of 3.3 V logic devices manufactured by Nexperia USA Inc. It is functionally equivalent to other hex inverters with Schmitt triggers but is optimized for low-voltage BiCMOS performance. The DB suffix indicates the specific SO14 package configuration within the broader 74LVT14 product line.

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 purpose of the IOFF circuitry?

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