Product details
Overview
74HC3G34DP,125 from Nexperia is a triple non-inverting buffer gate in TSSOP8 package, designed for signal conditioning and fan-out expansion in digital logic systems. It operates from 2.0 V to 6.0 V, delivers propagation delay as low as 8 ns at 6.0 V, supports -40 °C to +125 °C ambient range, and features input clamp diodes enabling overvoltage-tolerant interfacing - used in industrial control I/O expansion and mixed-voltage level translation.
For engineers reviewing the 74HC3G34DP,125 datasheet, 74HC3G34DP,125 pinout, 74HC3G34DP,125 application, or 74HC3G34DP,125 equivalent, key selection criteria include supply voltage compatibility (2.0–6.0 V), CMOS-level input thresholds, output drive strength (±25 mA), thermal rating (-40 °C to +125 °C), and TSSOP8 footprint constraints for high-density PCB layouts.
Technical Context
This device implements three independent, unidirectional buffer stages with no internal feedback or enable control - each input directly drives its corresponding output with unity gain and non-inverting polarity. All inputs incorporate integrated clamp diodes to GND and VCC, allowing safe interface to signals exceeding VCC when used with external current-limiting resistors.
It conforms to JEDEC JESD7A (2.0–6.0 V) and JESD8C (2.7–3.6 V) standards, supports HBM ESD >2000 V and CDM >1000 V, and exhibits static input leakage <±1.0 μA at 6.0 V - ensuring robust noise immunity and latch-up immunity exceeding 100 mA per JESD78 Class II Level B.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.0 V to 6.0 V - enables interoperability across 3.3 V and 5 V logic domains without level shifters. |
| Propagation Delay (tpd) | 8 ns (max) at VCC = 6.0 V - supports >50 MHz signal routing in timing-critical paths. |
| Output Drive Current | ±25 mA - sufficient to drive multiple 74HC inputs or small capacitive loads (<50 pF) without buffering. |
| Operating Temperature | -40 °C to +125 °C - qualified for under-hood industrial and extended-temperature embedded applications. |
| Input Clamp Diodes | Integrated anode-to-GND / cathode-to-VCC - permits safe connection of inputs to voltages up to VCC + 0.5 V using series resistors. |
| Power Dissipation (Ptot) | 250 mW at Tamb ≤ 96 °C (TSSOP8) - derates linearly at 4.6 mW/K above 96 °C for thermal design margin. |
| Input Capacitance (CI) | 1.5 pF - minimizes loading on driving sources and preserves signal edge integrity. |
Pinout & Package
TSSOP8 plastic thin shrink small outline package (SOT505-2); 8 leads; body width 3 mm; lead length 0.5 mm; pin 1 index located below marking code in lower-left corner.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3, 6 | 1A, 2A, 3A | Independent data inputs - each accepts CMOS-level signals and routes to corresponding output with no inversion. |
| 2, 5, 7 | 3Y, 2Y, 1Y | Corresponding buffered outputs - pin 2 = 3Y, pin 5 = 2Y, pin 7 = 1Y (IEC logic symbol order). |
| 4 | GND | Ground reference (0 V) - must be low-impedance connection to minimize switching noise coupling. |
| 8 | VCC | Positive supply rail - decoupling capacitor (100 nF ceramic) required within 5 mm of this pin. |
Key Features
| Feature | Design Value |
|---|---|
| Wide VCC range | 2.0–6.0 V operation - eliminates need for separate voltage translators in multi-rail systems. |
| Clamp diode protection | Internal input diodes to GND/VCC - allows direct interface to 12 V sensors or legacy TTL with only series resistors. |
| High noise immunity | Typical VIH = 4.2 V / VIL = 1.8 V at VCC = 6.0 V - provides >2.4 V noise margin in 5 V systems. |
| Latch-up immunity | Exceeds 100 mA per JESD78 Class II Level B - ensures reliability in noisy industrial environments. |
| Low dynamic power | CPD = 10 pF - limits switching power to <1.5 μW/MHz at 3.3 V, supporting battery-sensitive designs. |
Applications
| Industrial PLC I/O Expansion | Automotive Body Control Module |
|---|---|
Use Scenario: Buffering and isolating microcontroller GPIO lines driving relay drivers and optocouplers in programmable logic controllers.

Use Scenario: Driving multiple audio codec control registers (I²C address select, reset, mode config) from a single SoC GPIO bank. IC Role / Device Role / Timing Role: Logic-level fan-out extender - splits one control signal into three synchronized outputs with matched delay. Use Value: Prevents register configuration skew during power-up sequencing; CI = 1.5 pF avoids signal integrity issues at 1 MHz I²C rates. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar triple buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 74HC3G34DC,125 | VSSOP8 package (2.3 mm width); 0.2 mm thinner profile; identical electrical specs and pinout mapping. | Better suited for ultra-thin portable devices where board height is constrained; requires tighter placement tolerance due to smaller pad pitch. | Select when PCB stack height < 1.0 mm is mandatory and reflow profile supports fine-pitch VSSOP handling. |
| SN74LVC3G34DCUR | TI part in VSSOP8; 1.65–5.5 V supply; TTL-compatible inputs; higher ICC (max 10 μA vs. 20 μA at 6 V). | Supports 1.8 V logic domains; lacks input clamp diodes - requires external protection for overvoltage scenarios. | Choose only if operating below 2.0 V or integrating with LVC-family logic; avoid where input overvoltage tolerance is required. |
Compared with 74HC3G34DC,125, the DP variant offers wider body width (3.0 mm vs. 2.3 mm) for improved solder joint reliability in high-vibration environments; versus SN74LVC3G34DCUR, it provides superior overvoltage resilience and broader supply range but lacks 1.8 V compatibility.

FAQ
What is the maximum input voltage allowed beyond VCC for 74HC3G34DP,125?
The device includes integrated clamp diodes to VCC and GND. Per datasheet limiting values, inputs may exceed VCC by up to 0.5 V (i.e., VI ≤ VCC + 0.5 V) provided input clamping current remains within ±20 mA - achieved using external series resistors calculated per Ohm's Law based on expected overvoltage magnitude and duration.
Does 74HC3G34DP,125 support 3.3 V operation with guaranteed timing performance?
Yes. At VCC = 3.3 V, typical propagation delay is 12 ns (max 19 ns) over -40 °C to +125 °C, and VOH/VOL remain compliant with 3.3 V logic thresholds (VOH ≥ 2.97 V, VOL ≤ 0.33 V at IO = ±4 mA). These values are explicitly specified in Tables 7 and 8 of the Rev. 8 datasheet.
Can 74HC3G34DP,125 be used as a level shifter between 5 V and 3.3 V systems?
It can translate 3.3 V outputs to 5 V inputs safely, but not vice versa without external circuitry. As a CMOS-input device, it recognizes 3.3 V as HIGH when VCC = 5 V (VIH min = 3.15 V), but applying 5 V to its inputs while VCC = 3.3 V violates absolute maximum ratings - use only with series resistors and clamp diode engagement per Section 1 of the datasheet.
Is there a pin-compatible 74HCT3G34 variant available in TSSOP8?
Yes - 74HCT3G34DP,125 shares identical TSSOP8 (SOT505-2) packaging, pinout, and mechanical dimensions with 74HC3G34DP,125. Its key distinction is TTL-compatible input thresholds (VIH = 2.0 V min at VCC = 4.5–5.5 V), making it suitable for interfacing legacy 5 V TTL sources while maintaining same output drive and thermal specs.
