Product details
Overview
74HC2G34GW,125 from Nexperia is a dual non-inverting buffer gate in TSSOP6 (SOT363-2) package, operating from 2.0 V to 6.0 V supply, delivering balanced propagation delays as low as 8 ns at 6.0 V/50 pF, with CMOS-level input compatibility and ±25 mA output drive capability - used for signal buffering and level translation in industrial control logic interfaces.
For engineers reviewing the 74HC2G34GW,125 datasheet, 74HC2G34GW,125 pinout, 74HC2G34GW,125 application, or 74HC2G34GW,125 equivalent, key selection criteria include supply voltage range (2.0–6.0 V), guaranteed operation up to +125 °C, input clamp diodes enabling overvoltage-tolerant interfacing, and dual independent buffer channels with matched timing.
Technical Context
This device implements two independent CMOS-compatible non-inverting buffers with integrated input clamp diodes, supporting unlimited input rise/fall times and rail-to-rail output swing. Each channel features identical electrical behavior, with no internal feedback or enable control - strictly combinational logic with direct A→Y mapping.
It operates across industrial and extended temperature ranges (−40 °C to +125 °C), meets JESD7A and JESD8C standards, and provides HBM ESD robustness exceeding 2000 V. The design excludes Schmitt-trigger inputs, hysteresis, or power-down modes - optimized for deterministic, low-noise digital signal replication.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 2.0 V to 6.0 V - supports mixed-voltage system interfacing without level shifters |
| Propagation Delay | 8 ns max at VCC = 6.0 V, CL = 50 pF - enables reliable timing in 125 MHz+ clock domains |
| Output Drive | ±25 mA - sufficient to directly drive multiple 74HC inputs or small capacitive loads |
| Input Clamp Diodes | Integrated - allows safe interface to signals exceeding VCC when used with current-limiting resistors |
| Operating Temperature | −40 °C to +125 °C - qualified for under-hood, motor control, and high-ambient industrial environments |
| Power Dissipation | 250 mW max at 25 °C - derates linearly above 83 °C (3.7 mW/K) for thermal management predictability |
| Input Leakage | ±1.0 μA max at 125 °C - ensures stable logic states in low-power standby modes |
Pinout & Package
TSSOP6 (SOT363-2) plastic thin shrink small outline package: 6-pin, 1.25 mm body width, 0.65 mm lead pitch, surface-mount compatible with standard reflow profiles.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1A | First buffer input - accepts CMOS-level signals; clamped to GND/VCC |
| 2 | GND | Ground reference - must be low-impedance return path for both buffers |
| 3 | 2A | Second buffer input - electrically isolated from 1A; identical clamping behavior |
| 4 | 2Y | Second buffer output - non-inverting replica of 2A, capable of sourcing/sinking 25 mA |
| 5 | VCC | Positive supply - powers both buffers; decoupling capacitor required near pin |
| 6 | 1Y | First buffer output - non-inverting replica of 1A, fully buffered against load variations |
Key Features
| Feature | Design Value |
|---|---|
| Wide Supply Range | 2.0 V–6.0 V operation enables use across 3.3 V and 5 V systems without voltage translation |
| Balanced Propagation Delays | Matched tPLH/tPHL ensures consistent timing between dual channels for synchronized signal routing |
| Unlimited Input Slew Rate Support | No minimum rise/fall time requirement simplifies integration with slow-switching sensors or legacy logic |
| High Noise Immunity | Typical VIH/VIL margins >30% of VCC reduce susceptibility to ground bounce and crosstalk |
| Latch-Up Robustness | Exceeds 100 mA per JESD78 Class II Level B - prevents destructive latch-up during transient overstress |
Applications
| Industrial PLC I/O Expansion | Automated Test Equipment (ATE) Signal Conditioning |
|---|---|
Use Scenario: Buffering discrete sensor outputs (e.g., limit switches, proximity sensors) before feeding into microcontroller GPIOs with long PCB traces. IC Role / Device Role / Timing Role: Dual-channel signal replicator - isolates MCU from field-side transients while preserving edge integrity and timing alignment. Use Value: Clamp diodes allow direct connection to 12 V/24 V industrial signals via series resistors; 8 ns delay ensures deterministic sampling within 100 ns control cycles. |
Use Scenario: Driving multiple parallel test points from a single FPGA output in boundary-scan or functional test fixtures. IC Role / Device Role / Timing Role: Fan-out buffer - splits one high-speed control signal to four or more DUT inputs with matched skew. Use Value: ±25 mA drive strength sustains signal integrity across 50 pF trace+probe loads; 125 °C rating supports compact, fanless ATE enclosures. |
| Medical Diagnostic Instrument Data Paths | Smart Energy Meter Communication Interfaces |
Use Scenario: Isolating ADC data lines from microcontroller bus noise in portable ultrasound or ECG front-ends. IC Role / Device Role / Timing Role: Noise-suppressing buffer - breaks ground loops and attenuates high-frequency coupling between analog and digital sections. Use Value: CMOS input impedance (>1012 Ω) prevents loading of precision analog paths; 1.5 pF input capacitance minimizes signal distortion. |
Use Scenario: Level-shifting UART or SPI signals between 3.3 V meter SoC and 5 V legacy communication modules (e.g., PLC modems). IC Role / Device Role / Timing Role: Bidirectional voltage translator - leverages rail-to-rail output swing and input clamps to bridge voltage domains safely. Use Value: 2.0–6.0 V supply range permits direct 3.3 V or 5 V operation; −40 °C to +125 °C rating ensures reliability in outdoor meter enclosures. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 74HC2G34GV,125 | Same logic function and specs, but in SC-74 (SOT457) package - 3.1 mm body length vs. 2.2 mm for TSSOP6 | Less board space efficiency; higher thermal resistance (4.1 mW/K derating vs. 3.7 mW/K) | Select when legacy footprint compatibility or manual soldering preference outweighs miniaturization needs |
| SN74LVC2G34DBVR | Lower VCC range (1.65–5.5 V); TTL-compatible inputs only; 32 mA output drive; smaller 5-pin SOT-23-5 package | Not pin-compatible; lacks input clamp diodes; unsuitable for overvoltage-tolerant designs | Choose only if operating exclusively at 3.3 V and requiring higher drive strength in constrained layouts |
Compared with 74HC2G34GW,125, the GV variant trades compactness for mechanical familiarity, while the SN74LVC2G34DBVR sacrifices overvoltage resilience and dual-channel symmetry for lower voltage operation and marginally higher drive - neither offers drop-in replacement capability without layout or system-level validation.

FAQ
Can 74HC2G34GW,125 operate reliably at 2.0 V supply?
Yes - it is fully specified down to 2.0 V with guaranteed propagation delay ≤125 ns at 2.0 V/50 pF and VIH ≥1.5 V, making it suitable for battery-powered or low-voltage industrial systems where rail voltage may sag near cutoff thresholds.
Does this device support hot insertion or live swapping?
No - it lacks power-on reset, Ioff protection, or bus-hold circuitry. Applying VCC after signal inputs may cause undefined output states or excessive current through input clamps; always power VCC before applying input signals.
What is the maximum capacitive load this buffer can drive without timing degradation?
At 6.0 V supply, it maintains ≤20 ns propagation delay up to 50 pF load capacitance. Beyond that, delay increases approximately linearly with load; for 100 pF, expect ~35 ns typical delay - verify with actual board parasitics in critical timing paths.
How does the input clamp diode affect external resistor selection for overvoltage protection?
With clamp diodes rated for ±20 mA continuous forward current, a 1 kΩ series resistor limits input current to ≤12 mA when interfacing to 12 V signals at 0 V GND - ensuring safe operation within absolute maximum ratings without additional TVS devices.
