Product details
Overview
SN74LVC2G34DBVRG4 from Texas Instruments is a dual non-inverting buffer gate IC designed for 1.65-V to 5.5-V VCC operation, performing Y = A logic on two independent channels. It delivers ±24-mA output drive at 3.3 V, achieves 4.1 ns max propagation delay at 3.3 V, and supports 5.5-V-tolerant inputs - enabling level translation in portable audio, SSD, and embedded PC signal routing.
For engineers reviewing the SN74LVC2G34DBVRG4 datasheet, SN74LVC2G34DBVRG4 pinout, SN74LVC2G34DBVRG4 application, or SN74LVC2G34DBVRG4 equivalent, key selection criteria include Ioff-enabled partial-power-down protection, NanoFree™ SOT-23 (DBV) package compatibility, 10-µA max ICC quiescent current, and verified 2.90 mm × 1.60 mm footprint for space-constrained PCB layouts.
Technical Context
The SN74LVC2G34DBVRG4 implements two independent CMOS buffer gates with identical input-to-output logic (Y = A), each featuring rail-to-rail output swing and symmetric rise/fall times. Its Ioff circuitry actively disables outputs when VCC = 0 V, blocking back-current flow during live insertion or partial power-down sequences.
Input voltage tolerance up to 5.5 V allows interfacing with higher-voltage logic families while operating at lower VCC (e.g., 1.8 V or 3.3 V), making it suitable for mixed-supply systems. Output ground bounce (VOLP) remains below 0.8 V and VOH undershoot (VOHV) exceeds 2 V at 3.3 V/25°C - critical for noise margin integrity in high-speed digital interfaces.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 1.65 V to 5.5 V - enables single-supply operation across legacy 5-V, modern 3.3-V, and ultra-low-power 1.8-V systems |
| Max tpd | 4.1 ns at 3.3 V - supports signal integrity in ≤100 MHz digital paths without added timing margin |
| IOH/IOL | ±24 mA at 3.3 V - drives multiple CMOS loads or LEDs directly without external buffers |
| Ioff | <±10 µA at VCC = 0 V - prevents damaging backflow during hot-swap or power sequencing |
| Input Tolerance | 0 V to 5.5 V - allows down-translation from 5-V logic to 1.8-V/2.5-V domains without level shifters |
| ICC (max) | 10 µA - minimizes standby power in battery-powered portable audio and SSD applications |
Pinout & Package
SOT-23 (DBV) package: 2.90 mm × 1.60 mm body, 0.95 mm height, 6-pin surface-mount with gull-wing leads. Pin 1 marked by dot; pin 1 quadrant Q3 per tape-and-reel specification.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1A | Input 1 | First buffer input; accepts 0–5.5 V regardless of VCC, enabling robust interface to diverse logic families |
| 1Y | Output 1 | Non-inverting buffered output; drives up to ±24 mA at 3.3 V with rail-aligned VOH/VOL |
| 2A | Input 2 | Second independent buffer input; electrically isolated from 1A/1Y path |
| 2Y | Output 2 | Non-inverting buffered output; shares same VCC/GND rails but operates independently |
| GND | Ground | Reference return for all internal logic and output drivers; must be low-impedance for noise control |
| VCC | Power | Primary supply for logic core and output stages; requires local 0.1-µF bypass capacitor per TI layout guidelines |
Key Features
| Feature | Design Value |
|---|---|
| NanoFree™ packaging | Dies-as-package construction eliminates leadframe; reduces size to 2.90 mm × 1.60 mm and improves thermal resistance (RθJA = 165°C/W) |
| Ioff partial-power-down | Automatically disables outputs when VCC = 0 V, preventing back-current damage during hot-plug or multi-rail sequencing |
| 5.5-V tolerant inputs | Accepts input voltages beyond VCC (up to 5.5 V), eliminating need for external level translators in mixed-voltage designs |
| High-drive capability | ±24 mA output at 3.3 V supports direct LED driving or fan-out to ≥10 standard CMOS loads |
| Low dynamic power | 15 pF typical power dissipation capacitance (Cpd) at 3.3 V limits switching current and EMI in high-frequency operation |
Applications
| Audio Signal Routing | Solid-State Drive (SSD) Control |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual buffer gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC2G34DBVR | Same die, identical electrical specs; differs only in RoHS-compliant NiPdAu lead finish vs. SN74LVC2G34DBVRG4's matte tin (NIPDAU) | No functional difference; both rated for –40°C to 125°C and share same SOT-23 (DBV) package dimensions | Select SN74LVC2G34DBVRG4 when matte tin finish is required for solderability or legacy process compatibility. |
| SN74LVC1G34DBVR | Single-channel variant; same VCC range, drive strength, and Ioff, but half the channel count and reduced pin count (5-pin SOT-23) | Used where only one buffer is needed; occupies less board area but requires two devices for dual-channel functionality | Choose SN74LVC1G34DBVR for space-constrained single-buffer applications; SN74LVC2G34DBVRG4 preferred for dual-channel density. |
