Product details
Overview
74LVC3G34GS,115 from Nexperia is a triple non-inverting buffer IC with Schmitt-trigger inputs, designed for level translation between 3.3 V and 5 V logic domains in space-constrained mixed-voltage systems. It operates from 1.65 V to 5.5 V, delivers ±24 mA output drive at 3.0 V, features IOFF partial power-down protection, and is rated for -40 °C to +125 °C operation in the XSON8 (SOT1203) package.
For engineers reviewing the 74LVC3G34GS,115 datasheet, 74LVC3G34GS,115 pinout, 74LVC3G34GS,115 application, or 74LVC3G34GS,115 equivalent, key selection criteria include input overvoltage tolerance to 5.5 V, guaranteed propagation delay ≤5.1 ns at 3.3 V, IOFF-enabled backflow prevention during power sequencing, and compatibility with JEDEC standards JESD8-7/8-5/8C/36 across voltage ranges.
Technical Context
This device implements three independent CMOS buffer gates with hysteresis-equipped Schmitt-trigger inputs, enabling robust signal conditioning of slow-rising or noisy digital signals. Each channel provides true non-inverting logic translation without inversion or timing skew between channels.
The IOFF circuit activates automatically when VCC = 0 V, disabling all outputs and blocking current flow from powered inputs into the unpowered device-critical for hot-swap and multi-rail power sequencing in portable and industrial control systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply voltage range | 1.65 V to 5.5 V - supports direct interface with both 1.8 V, 2.5 V, 3.3 V, and 5 V logic families |
| Input overvoltage tolerance | Up to 5.5 V - enables safe connection to 5 V sources while operating at 1.65–3.3 V supply |
| Output drive strength | ±24 mA at VCC = 3.0 V - sufficient to drive multiple LVC loads or moderate capacitive traces |
| Propagation delay | ≤5.1 ns max at VCC = 3.0–3.6 V - ensures timing integrity in high-speed data paths up to ~100 MHz |
| IOFF leakage current | ±2 μA max at VCC = 0 V - prevents damaging backfeed current during partial power-down |
| Operating temperature | -40 °C to +125 °C - qualified for under-hood automotive, industrial motor control, and telecom infrastructure |

Pinout & Package
XSON8 (SOT1203) package: 1.35 mm × 1.0 mm × 0.35 mm body, no leads, 8 terminals, wettable flank terminations for automated optical inspection.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1A | Channel 1 input - accepts 3.3 V or 5 V logic levels regardless of VCC |
| 2 | 3Y | Channel 3 output - driven low/high with full rail-to-rail swing referenced to VCC |
| 3 | 1Y | Channel 1 output - non-inverted replica of 1A with Schmitt-trigger hysteresis |
| 4 | VCC | Positive supply - powers all three buffers; IOFF active when VCC = 0 V |
| 5 | 2Y | Channel 2 output - electrically isolated from other channels; supports independent loading |
| 6 | 2A | Channel 2 input - identical electrical behavior to 1A and 3A |
| 7 | 3A | Channel 3 input - tolerant of slow edges due to Schmitt-trigger threshold spacing |
| 8 | GND | Ground reference - return path for all supply and signal currents; must be low-impedance |
Key Features

FAQ
What is the maximum input voltage the 74LVC3G34GS,115 can tolerate when VCC = 1.8 V?
The device supports overvoltage-tolerant inputs up to 5.5 V regardless of VCC level. When VCC = 1.8 V, inputs may safely swing from 0 V to 5.5 V without damage or latch-up, enabling direct connection to 5 V microcontrollers or sensors while operating from a 1.8 V rail.
Does the 74LVC3G34GS,115 support hot-swap insertion in live backplanes?
Yes - its IOFF circuitry actively disables outputs and limits backflow current to ±2 μA when VCC = 0 V, allowing safe insertion into powered systems. This eliminates risk of bus contention or supply rail collapse during hot-swap events in modular industrial or telecom equipment.
How does the Schmitt-trigger input improve noise immunity compared to standard CMOS inputs?
Schmitt-trigger inputs provide hysteresis: VIH and VIL thresholds differ by ≥0.3 V (e.g., 2.0 V vs. 0.8 V at 3.3 V). This prevents multiple output transitions caused by slow-rising signals or noise near the switching point, making the device robust against EMI on long PCB traces or mechanical switch bounce in control panels.
Can the 74LVC3G34GS,115 drive a 50 pF load at 10 MHz while maintaining timing integrity?
Yes - with CPD = 14 pF and tpd ≤5.1 ns at 3.3 V, the device delivers <0.7 ns of additional delay per 10 pF load increase. At 10 MHz (100 ns period), the total propagation uncertainty remains <5% of the cycle, preserving setup/hold margins for synchronous interfaces like SPI or parallel control buses.
