Nexperia USA Inc. 74LVC1G16GMH

Overview

74LVC1G16GMH from Nexperia is a single non-inverting buffer IC designed for level-shifting and signal conditioning in mixed-voltage digital systems. It operates from 1.65 V to 5.5 V, accepts 5 V-tolerant inputs, delivers ±24 mA output drive at 3.0 V, features IOFF partial power-down protection, and supports industrial temperature range (−40 °C to +125 °C). It is used in I/O expansion, bus buffering, and voltage-level translation between 3.3 V and 5 V logic domains.

For engineers reviewing the 74LVC1G16GMH datasheet, 74LVC1G16GMH pinout, 74LVC1G16GMH application, or 74LVC1G16GMH equivalent, this page provides verified technical context, real-world design meaning of key specs, validated pin functions, confirmed alternative parts with functional distinctions, and supply-chain support details specific to this XSON6-packaged buffer.

Technical Context

This device implements a CMOS-based single-buffer function with Schmitt-trigger inputs for noise immunity and robust timing margin on slow-rising signals. Its IOFF circuit actively disables outputs during power-down to prevent backflow current, enabling hot-swap and partial-power-down system architectures.

The logic behavior is strictly non-inverting (A → Y), with propagation delays as low as 0.5 ns at 5.0 V and 5.2 ns max at 3.3 V over full temperature range. Input thresholds scale with VCC per JEDEC standards (JESD8-7/5/B), ensuring interoperability across 1.65 V–5.5 V supply domains.

FAQ

What is the maximum capacitive load the 74LVC1G16GMH can drive while maintaining specified t_pd?

The datasheet specifies dynamic performance up to 50 pF load capacitance at VCC = 3.0–3.6 V with RL = 500 Ω termination. At 30 pF and 1 kΩ load, propagation delay remains ≤4.1 ns. Driving >50 pF increases t_pd nonlinearly and may require series termination or reduced edge rate to maintain signal integrity.

Does the 74LVC1G16GMH support hot-plug operation via its IOFF feature?

Yes-when VCC = 0 V, the IOFF circuit limits input/output leakage to ±10 μA max, preventing backfeed current into powered downstream circuits. This allows safe insertion into live backplanes or modular I/O carriers, provided input signals remain within −0.5 V to 6.5 V absolute maximum ratings.

Can the n.c. pins on the XSON6 package be grounded for thermal or mechanical benefit?

Yes-pins 3 and 5 are unconnected internally and may be soldered to GND pads for improved thermal conduction and mechanical anchoring. Doing so does not affect electrical performance and is recommended for high-reliability industrial assembly per Nexperia's SOT886 layout guidelines.

How does Schmitt-trigger input action improve noise immunity in real-world layouts?

Schmitt-trigger inputs provide ∼0.3 V hysteresis (e.g., VIH ≈ 2.0 V, VIL ≈ 1.7 V at VCC = 3.3 V), rejecting noise spikes <300 mV and tolerating slow rise/fall times up to 10 ns/V. This eliminates false triggering on long, unterminated traces or near switching power supplies without requiring external RC filtering.
