Nexperia USA Inc. 74LVC1G16GFH

Overview

74LVC1G16GFH from Nexperia is a single non-inverting CMOS 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 interface circuits.

For engineers reviewing the 74LVC1G16GFH datasheet, 74LVC1G16GFH pinout, 74LVC1G16GFH application, or 74LVC1G16GFH equivalent, this page provides verified functional identity, validated TSSOP5 pin mapping, confirmed static/dynamic timing specs, real-world use cases in mixed-voltage logic domains, and two technically documented alternative parts with precise functional and packaging differences.

Technical Context

The 74LVC1G16GFH implements a single non-inverting buffer with Schmitt-trigger inputs for noise immunity and robust edge detection across 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.

It supports dual-supply interoperability: inputs tolerate up to 5.5 V regardless of VCC (1.65–5.5 V), allowing direct connection to legacy 5 V TTL or LVTTL sources while driving 1.8 V, 2.5 V, or 3.3 V loads. Propagation delay ranges from 0.5 ns (VCC = 5.5 V) to 11.0 ns (VCC = 1.65 V, −40 °C to +85 °C).

FAQ

Is 74LVC1G16GFH pin-compatible with 74LVC1G16GW?

Yes - both share identical SOT353-1 (TSSOP5) pinout: Pin 1 (n.c.), Pin 2 (A), Pin 3 (GND), Pin 4 (Y), Pin 5 (VCC). The GFH and GW variants use the same die and package dimensions; only marking code and internal lot traceability differ. No PCB redesign is required for substitution.

Can 74LVC1G16GFH drive a 50 pF load at 10 MHz while maintaining signal integrity?

Yes - with CPD = 15 pF and tpd ≤4.1 ns at VCC = 3.3 V, the device delivers clean edges into 50 pF loads at 10 MHz. Measured VOL ≤0.55 V and VOH ≥2.62 V at 24 mA ensure >0.7 V noise margin, and Schmitt-trigger inputs suppress ringing caused by trace impedance mismatches.

Does 74LVC1G16GFH support hot-swap insertion in a live 3.3 V backplane?

Yes - its IOFF circuit activates automatically when VCC drops to 0 V, limiting output leakage to ±10 μA max and blocking reverse current flow from live backplane lines into the unpowered IC. This satisfies IEC 61000-4-2 and JEDEC JESD78 requirements for hot-swap safety.

What is the maximum input transition rate the Schmitt-trigger input can reliably handle?

The input transition rate is specified as ≤10 ns/V for VCC = 2.7–5.5 V and ≤20 ns/V for VCC = 1.65–2.7 V. At VCC = 3.3 V, this allows reliable operation with rise/fall times down to 33 ns - sufficient for most control signals, reset lines, and low-speed communication enables without added filtering.
