74LVC1G16GFH

Overview

The Nexperia 74LVC1G16GFH is a single buffer within the LVC logic family, designed for low-power and low-voltage applications. It operates across a wide supply voltage range of 1.65 V to 5.5 V and features Schmitt trigger inputs for high noise immunity. The device supports partial power-down via IOFF circuitry and accepts input voltages up to 5 V, enabling direct interfacing with TTL levels and mixed 3.3 V/5 V environments. It provides ±24 mA output drive at 3.0 V and complies with JEDEC standards.

Feature Summary

• Schmitt trigger action on all inputs ensures tolerance to slower signal rise and fall times.
• IOFF circuitry disables outputs during power-down to prevent damaging backflow currents.
• Inputs accept voltages up to 5 V, allowing direct interface with TTL levels and mixed voltage systems.

Applications

• Partial power-down applications requiring controlled output disabling
• Mixed 3.3 V and 5 V logic environments
• Interfaces requiring high noise immunity

Procurement Notes

Verify that the suffix GFH corresponds to the specific package variant intended for your design, as the datasheet lists GW (TSSOP5) and GM (XSON6). Confirm the required temperature range (-40 °C to +125 °C) matches your operational environment. Ensure input transition rates comply with JEDEC standards for the selected supply voltage to maintain signal integrity.

Selection Notes

Select this component when a single-buffer function with Schmitt trigger inputs is required in space-constrained designs. It is suitable for translating signals between different voltage domains without external components. Consider the ±24 mA drive capability for moderate load requirements and verify ESD protection meets system safety standards.

Part Context

The 74LVC1G16 belongs to Nexperia's LVC (Low-Voltage CMOS) series, which offers improved performance over standard CMOS while maintaining compatibility with legacy logic families. This single-buffer configuration provides signal regeneration and isolation in digital circuits, supporting modern low-power embedded systems and portable electronics.
