74LVC1G16GWH

Overview

The Nexperia 74LVC1G16GWH is a single buffer in the 74LVC logic family, housed in a TSSOP5 (SOT353-1) package. It operates on a supply voltage range of 1.65 V to 5.5 V with inputs tolerant up to 5.5 V. The device features Schmitt trigger action for noise immunity and IOFF circuitry for partial power-down support. Static characteristics include a maximum supply current of 20 μA at -40 °C to +85 °C and 200 μA at -40 °C to +125 °C. Dynamic performance shows propagation delays ranging from 1.0 ns to 11.0 ns depending on voltage and temperature.

Feature Summary

• Schmitt trigger input action provides high tolerance for slow input rise and fall times.
• IOFF circuitry disables outputs during power-down to prevent damaging backflow currents.
• Inputs accept voltages up to 5.5 V, enabling direct interfacing with 5 V logic devices.

Applications

• Mixed 3.3 V and 5 V logic environments
• Partial power-down applications requiring backflow prevention
• Signal buffering with slow transition time requirements

Procurement Notes

Verify the specific suffix 'H' against the official datasheet ordering information table. The provided source document lists standard suffixes such as 'GW' and 'GM'. Confirm that the 'H' designation corresponds to the correct tape-and-reel packaging format or variant intended for your assembly process before finalizing procurement.

Selection Notes

Select this component when a single non-inverting buffer with Schmitt trigger inputs is required. It supports wide supply voltages from 1.65 V to 5.5 V and offers 5 V tolerant inputs. Ensure the application benefits from the IOFF feature for power-down protection and requires high noise immunity due to slow signal transitions.

Part Context

This part belongs to the Nexperia 74LVC1G16 series of single buffers. It is designed for low-power, low-voltage digital applications. The device is specified for ambient temperatures from -40 °C to +125 °C and complies with JEDEC standards for various voltage ranges within its operating window.

Replacement Considerations

The datasheet does not list confirmed substitute part numbers. Verify compatibility with generic 74LVC single buffers if cross-referencing, ensuring pinout and electrical specifications match exactly.
