Nexperia USA Inc. 74LVC1G34GM,115

Overview

74LVC1G34GM,115 from Nexperia is a single non-inverting CMOS buffer with Schmitt-trigger inputs, designed for level translation between 1.65 V–5.5 V logic domains in space-constrained mixed-voltage systems. It delivers ±24 mA output drive at 3.0 V, supports IOFF partial power-down mode, and operates across –40 °C to +125 °C in the XSON6 (SOT886) package.

For engineers reviewing the 74LVC1G34GM,115 datasheet, 74LVC1G34GM,115 pinout, 74LVC1G34GM,115 application, or 74LVC1G34GM,115 equivalent, key selection criteria include its overvoltage-tolerant 5.5 V inputs, sub-1.0 ns propagation delay at 5 V, IOFF-enabled backflow current prevention, and compatibility with TTL-level interfaces in industrial control and portable electronics.

Technical Context

This device implements a single unidirectional buffer with hysteresis on the input (Schmitt-trigger), enabling robust operation with slow-rising or noisy signals. Its IOFF circuit actively disables outputs during power-down, blocking reverse current flow when VCC = 0 V.

The logic function is strictly non-inverting (A → Y), with VIH/VIL thresholds scaling with VCC per JEDEC standards JESD8-7/8C/36. Input clamping and ESD protection (HBM >2000 V, CDM >1000 V) are integrated without external components.

FAQ

Can 74LVC1G34GM,115 operate with VCC = 1.65 V while receiving a 5 V input signal?

Yes. The device features overvoltage-tolerant inputs rated to 5.5 V independent of VCC. At VCC = 1.65 V, the input accepts 0–5 V signals without damage or latch-up, enabling safe interfacing with higher-voltage peripherals in partial-power systems.

What is the significance of the IOFF feature in real-world system design?

IOFF disables the output stage when VCC = 0 V, limiting backflow current to ≤±2 μA. This prevents unintended current paths during power sequencing - critical in hot-plug modules, battery-backed subsystems, and multi-rail FPGAs where one supply may be active while others are off.

Does the Schmitt-trigger input eliminate the need for external RC filtering on noisy lines?

It significantly reduces but does not fully eliminate the need for filtering. With typical hysteresis ≥0.3 V, the input rejects noise spikes <300 mV peak-to-peak and tolerates rise/fall times up to 20 ns/V. For severe EMI environments (e.g., motor drives), a series resistor + small capacitor remains recommended.

Is the XSON6 (SOT886) package compatible with standard reflow profiles for lead-free assembly?

Yes. The SOT886 package is qualified for IPC/JEDEC J-STD-020 moisture sensitivity level 1 (MSL-1) and supports standard Pb-free reflow profiles with peak temperatures up to 260 °C. Its 0.5 mm profile and no-lead construction require precise stencil aperture design and nitrogen-assisted reflow for optimal void control.
