Product details
Overview
74LVC2G34GV,125 from Nexperia is a dual non-inverting buffer gate in SC-74 (TSOP6) package with 6 terminals, operating from 1.65 V to 5.5 V supply, featuring Schmitt-trigger inputs for noise immunity and IOFF partial power-down protection. It enables level translation between 3.3 V and 5 V logic domains in mixed-voltage I/O interfaces on embedded control boards.
For engineers reviewing the 74LVC2G34GV,125 datasheet, 74LVC2G34GV,125 pinout, 74LVC2G34GV,125 application, or 74LVC2G34GV,125 equivalent, key selection criteria include its ±24 mA output drive at 3.0 V, -40 °C to +125 °C temperature rating, IOFF-enabled bus isolation during power sequencing, and compatibility with TTL-level inputs.
Technical Context
This device implements two independent CMOS buffer gates with Schmitt-trigger inputs, enabling robust signal conditioning of slow-rising or noisy digital signals. Each channel provides true non-inverting logic (A → Y), with input thresholds scaled to VCC for reliable operation across 1.65 V–5.5 V.
The IOFF circuit actively disables outputs when VCC = 0 V, blocking backflow current up to ±50 mA and supporting hot-swap and partial power-down system architectures. Input overvoltage tolerance to 5.5 V allows safe interfacing with higher-voltage peripherals without external clamping.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.65 V to 5.5 V - supports single-supply operation across LVC logic families and mixed-voltage board designs |
| Output Drive Strength | ±24 mA at VCC = 3.0 V - drives standard 50 Ω transmission lines or multiple 74LVC inputs without buffering |
| Propagation Delay | 2.2 ns typical at VCC = 3.3 V - enables timing-critical signal routing in high-speed digital control paths |
| IOFF Leakage Current | ±2 μA max at VCC = 0 V - ensures bus integrity during power-down without external isolation switches |
| Input Voltage Tolerance | Up to 5.5 V regardless of VCC - permits direct connection to 5 V microcontrollers or sensors while powered from 3.3 V |
| Operating Temperature | -40 °C to +125 °C - qualified for industrial motor control, automotive body electronics, and outdoor IoT edge nodes |
| ESD Protection | HBM > 2000 V, CDM > 1000 V - withstands handling and board-level ESD events without derating or shielding |
Pinout & Package
74LVC2G34GV,125 uses the SC-74 (TSOP6) package per SOT457 outline: plastic surface-mounted, 6-lead, body size 3.1 mm × 1.7 mm × 0.95 mm, with gull-wing leads and pin 1 index marked by notch or dot.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1A | First buffer input - accepts 3.3 V or 5 V logic levels; Schmitt-triggered for noise margin |
| 2 | GND | Ground reference - must be low-impedance return path for both buffers and IOFF circuitry |
| 3 | 2A | Second buffer input - electrically isolated from 1A; identical input characteristics |
| 4 | 2Y | Second buffer output - delivers full rail-to-rail CMOS swing with ±24 mA sink/source capability |
| 5 | VCC | Supply voltage - powers both buffers and IOFF control; decoupling capacitor required within 5 mm |
| 6 | 1Y | First buffer output - non-inverting replica of 1A; compatible with 74LVC, 74ALVC, and TTL loads |
Key Features
| Feature | Design Value |
|---|---|
| Wide Supply Range | 1.65 V–5.5 V operation eliminates need for separate level-shifter ICs in multi-rail systems |
| Schmitt-Trigger Inputs | Hysteresis > 0.3 V at VCC = 3.3 V - rejects < 10 ns glitches and sustains clean edges on RC-filtered sensor outputs |
| IOFF Partial Power-Down | Outputs go high-impedance when VCC = 0 V - prevents backfeeding into powered subsystems during firmware updates or sleep modes |
| TTL-Compatible Inputs | VIH ≤ 2.0 V, VIL ≥ 0.8 V at VCC = 3.3 V - directly interfaces legacy 5 V microcontrollers without pull-up resistors |
| Latch-Up Immunity | Exceeds 250 mA per JEDEC JESD78 - survives transient overcurrent events in industrial I/O modules |
Applications
| Industrial PLC I/O Expansion | Automotive Body Control Module |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC2G34DBVR | TI part in SOT-23-6 package; identical logic function but no IOFF circuitry | Not suitable for partial power-down systems requiring backflow prevention | Select only if board-level power sequencing guarantees simultaneous VCC ramp-up/down across all connected ICs |
| 74AUP2G34GW,125 | Nexperia AUP variant: lower ICC (0.5 μA typ), slower tpd (5.1 ns min at 3.3 V), same IOFF and pinout | Better for ultra-low-power always-on monitoring nodes where speed < 20 MHz suffices | Choose when static current budget is tighter than propagation delay requirement, e.g., battery-backed real-time clocks |
Compared with SN74LVC2G34DBVR, the 74LVC2G34GV,125 adds critical IOFF protection for hot-plug and domain-isolation use cases; versus 74AUP2G34GW,125, it trades 3× higher speed for 2× higher active current-making it optimal for industrial control loops requiring sub-10 ns timing margins.

FAQ
Does 74LVC2G34GV,125 support 1.8 V operation?
Yes. The device is fully specified from 1.65 V to 5.5 V, including 1.8 V nominal supply. At VCC = 1.8 V, VIH is 0.65 × VCC = 1.17 V and VIL is 0.35 × VCC = 0.63 V, meeting standard 1.8 V logic thresholds. Propagation delay increases to 3.8 ns typical, and output drive reduces to ±12 mA.
Can 74LVC2G34GV,125 replace 74LVC2G125 in existing designs?
No. The 74LVC2G125 is a 3-state buffer with OE control, while the 74LVC2G34 is a true non-inverting buffer with no output enable. They share pinout and supply specs, but functional replacement requires redesigning OE logic and verifying bus contention behavior during tri-state transitions.
What is the maximum capacitive load this buffer can drive reliably?
At VCC = 3.3 V and Tamb = 25 °C, the device maintains < 5 ns tpd driving 50 pF loads per output, as verified in Table 10 test conditions. For heavier loads (> 75 pF), rise/fall times degrade linearly; layout best practices (short traces, local decoupling) are required to maintain signal integrity beyond 100 pF.
Is the SC-74 (SOT457) package RoHS-compliant and lead-free?
Yes. The 74LVC2G34GV,125 in SOT457 package meets RoHS Directive 2011/65/EU and is lead-free, halogen-free, and compliant with Nexperia's environmental policy. Terminal finish is matte tin (Sn), with peak reflow temperature rated to 260 °C per JEDEC J-STD-020.
