74LVC2G16GFH

Overview

The Nexperia 74LVC2G16GFH is a dual buffer gate operating within a supply voltage range of 1.65 V to 5.5 V. It features Schmitt-trigger inputs for noise immunity and IOFF circuitry for partial power-down protection. The device supports direct interface with TTL levels and offers overvoltage tolerant inputs up to 5.5 V. It complies with JEDEC standards for various voltage ranges and provides ESD protection exceeding 2000 V (HBM) and 1000 V (CDM). Operating temperatures span from -40 °C to +85 °C and -40 °C to +125 °C.

Feature Summary

• Schmitt-trigger action at all inputs ensures tolerance for slower input rise and fall times.
• IOFF circuitry disables outputs during partial power-down to prevent damaging backflow currents.
• Inputs are overvoltage tolerant, allowing direct interfacing with 3.3 V and 5 V devices in mixed environments.

Applications

• Mixed 3.3 V and 5 V environment translation
• Partial power-down applications requiring IOFF functionality
• Buffering signals with slow rise and fall times

Procurement Notes

Verify the specific suffix GFH against the official ordering information table, as the provided datasheet lists GW and GM variants. Confirm package type SOT363-2 or SOT886 matches design requirements. Ensure temperature range specifications align with application constraints. Cross-reference marking codes YU for identification. Validate that the component meets required JEDEC compliance standards for the target voltage domain.

Selection Notes

Select this component when dual buffering with Schmitt-trigger inputs is required for noisy environments. The IOFF feature is critical for systems needing safe partial power-down modes. Verify compatibility with both 3.3 V and 5 V logic levels due to overvoltage tolerant inputs. Consider the specified temperature ranges and ESD protection levels for robustness in harsh conditions.

Part Context

The 74LVC2G16 belongs to the LVC family of CMOS logic devices designed for low-voltage operation. It serves as a dual buffer gate, providing signal isolation and level shifting capabilities. The device integrates Schmitt triggers and IOFF protection, distinguishing it from standard buffers. It is intended for use in mixed-voltage digital systems requiring reliable signal transmission.

Replacement Considerations

Public confirmed substitute part numbers are not available in the source material. Verify pinout compatibility and electrical characteristics before considering any alternative components from other manufacturers.
