Product details
Overview
SN74LVC1G34DBVRG4 from Texas Instruments is a single non-inverting CMOS buffer gate designed for 1.65V–5.5V operation, delivering ±24mA output drive at 3.3V, 3.5ns max propagation delay (tpd), and 1μA max ICC, used in signal conditioning and level translation between mixed-voltage logic domains in portable audio and embedded interfaces.
For engineers reviewing the SN74LVC1G34DBVRG4 datasheet, SN74LVC1G34DBVRG4 pinout, SN74LVC1G34DBVRG4 application, or SN74LVC1G34DBVRG4 equivalent, this page delivers verified package mapping (SOT-23-5), confirmed Ioff-enabled live insertion support, validated 5.5V-tolerant inputs, and real-world timing performance across VCC and temperature ranges - all critical for low-power, space-constrained digital interface design.
Technical Context
The SN74LVC1G34DBVRG4 implements a single positive-logic buffer (Y = A) with rail-to-rail input voltage tolerance up to 5.5V and down-translation capability to VCC, enabling interoperability between 5V legacy peripherals and 1.8V/3.3V system-on-chip domains. Its Ioff circuitry actively disables outputs during partial power-down, blocking back-drive current and supporting hot-plug operation.
It operates across –40°C to 125°C ambient (per SOT-23 package rating), maintains sub-4ns tpd at 3.3V/CL=15pF, and exhibits <3.5pF input capacitance (Ci) and 16pF typical power-dissipation capacitance (Cpd), making it suitable for high-speed, low-noise signal routing in bandwidth-sensitive consumer and industrial control paths.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 1.65V to 5.5V - supports direct interfacing with 1.8V, 2.5V, 3.3V, and 5V logic families without external level shifters. |
| tpd (max) | 3.5ns at VCC = 3.3V, CL = 15pF - enables reliable operation up to ~100MHz clock/data rates in buffered signal paths. |
| Output Drive | ±24mA at VCC = 3.3V - sufficient to directly drive LEDs, multiple CMOS inputs, or moderate capacitive loads (<50pF). |
| Ioff Support | Active during power-off - prevents damaging current flow when VCC = 0V while inputs remain biased, enabling live insertion. |
| Input Voltage Tolerance | Up to 5.5V independent of VCC - allows safe connection to 5V signals even when powered from 1.8V or 2.5V rails. |
| ICC (max) | 10μA over full temperature range - ensures ultra-low static power draw in battery-powered and always-on subsystems. |
| ESD Rating | ±2kV HBM - meets industrial-grade robustness requirements for handling and board-level integration. |
Pinout & Package
SOT-23-5 (DBV) package: 2.90mm × 2.80mm body, 5-pin surface-mount, lead-free and RoHS-compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (NC) | No internal connection | Unused pad - must be left floating or grounded per layout best practice; no electrical function. |
| 2 (A) | Input | Single logic input accepting 0–5.5V; compatible with TTL and CMOS thresholds across entire VCC range. |
| 3 (GND) | Ground reference | Primary return path for output sink current and supply return; requires low-impedance PCB connection. |
| 4 (Y) | Output | Non-inverting buffered output; drives loads up to ±24mA while maintaining VOL ≤ 0.55V and VOH ≥ 2.3V at 3.3V. |
| 5 (VCC) | Power supply | Core supply rail (1.65–5.5V); requires local 0.1μF bypass capacitor placed adjacent to pin for noise suppression. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-small footprint | 0.64mm² DPW package option available - but SN74LVC1G34DBVRG4 uses standard SOT-23-5 (2.9×2.8mm), balancing density and manufacturability. |
| 5V-tolerant inputs | Accepts 0–5.5V input regardless of VCC - eliminates need for external clamping diodes when interfacing with 5V microcontrollers or sensors. |
| Ioff protection | Enables partial power-down mode - blocks current flow between powered and unpowered sections, critical for modular systems and hot-swap designs. |
| Low dynamic power | Cpd = 16pF at 3.3V - minimizes switching current and EMI in high-frequency data lines such as I²C pull-up buffers or reset signal extenders. |
| Wide temperature range | Rated for –40°C to +125°C ambient - qualified for under-hood automotive modules, industrial PLC I/O, and telecom power management circuits. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar buffer gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 74LVC1G34GW,125 (Nexperia) |
Same logic function and 1.65–5.5V VCC range, but SC-70-5 package (2.0×2.1mm); slightly higher max tpd (4.1ns @3.3V). | Preferred where board space is tighter than thermal budget; lower RθJA (371°C/W vs. 357°C/W) but same Ioff and 5.5V-tolerant input spec. | Select when footprint reduction outweighs marginal timing penalty and when sourcing diversity is required. |
| MC74VHC1G07DTT1G (onsemi) |
Open-drain output (no push-pull), identical VCC range and 5.5V-tolerant inputs, but lacks Ioff and has higher ICC (max 2μA). | Suitable only where active pull-down is needed (e.g., wired-AND buses); not drop-in for push-pull drive or hot-swap use cases. | Choose only for open-drain applications; avoid where SN74LVC1G34DBVRG4's Ioff, push-pull drive, or guaranteed VOL/VOH are required. |
Compared with 74LVC1G34GW,125 and MC74VHC1G07DTT1G, the SN74LVC1G34DBVRG4 uniquely combines SOT-23 manufacturability, Ioff-enabled live insertion, and sub-3.5ns timing - making it optimal for space-constrained, mixed-voltage embedded systems requiring robust, plug-and-play signal integrity.

FAQ
What is the maximum operating temperature for SN74LVC1G34DBVRG4?
The SN74LVC1G34DBVRG4 is rated for operation from –40°C to +125°C ambient temperature, as specified for its SOT-23-5 (DBV) package in the Recommended Operating Conditions table. This rating applies across the full 1.65V–5.5V VCC range and supports deployment in under-hood automotive, industrial control, and high-density computing environments where thermal margins are constrained. The device's RθJA of 357.1°C/W confirms thermal viability within this envelope when proper PCB copper area is provided.
Does SN74LVC1G34DBVRG4 support 5V logic inputs when powered from 3.3V?
Yes, SN74LVC1G34DBVRG4 supports input voltages up to 5.5V regardless of VCC level - including when VCC = 3.3V. This 5V-tolerant input capability is explicitly guaranteed in the datasheet's Recommended Operating Conditions and Absolute Maximum Ratings, enabling direct connection to 5V microcontrollers, sensors, or legacy peripherals without external level-shifting circuitry. The input structure inherently translates down to VCC, preserving logic thresholds and noise margins.
Can SN74LVC1G34DBVRG4 drive an LED directly?
Yes, SN74LVC1G34DBVRG4 can drive an LED directly: at VCC = 3.3V, it delivers up to 24mA sink/source current, sufficient for standard 2–20mA indicator LEDs. Its VOL ≤ 0.55V and VOH ≥ 2.3V ensure reliable on/off states, and its low ICC (≤10μA) minimizes standby power. For sustained LED operation, verify that total power dissipation (P = I²R + V×I) stays within the SOT-23 package's thermal limits - typically feasible for single-LED applications at room temperature.
What does the "G4" suffix mean in SN74LVC1G34DBVRG4?
The "G4" suffix in SN74LVC1G34DBVRG4 indicates TI's Green packaging standard: lead-free terminations, halogen-free materials, and RoHS compliance. It does not denote functional or parametric differences from earlier revisions like SN74LVC1G34DBVR - all electrical specifications, timing, and pinout remain identical. The G4 marking assures environmental compliance for global commercial and industrial deployments without design requalification.
Is SN74LVC1G34DBVRG4 pin-compatible with other 5-pin logic buffers?
SN74LVC1G34DBVRG4 follows the industry-standard SOT-23-5 pinout (pin 1: NC, pin 2: A, pin 3: GND, pin 4: Y, pin 5: VCC), matching TI's own SN74LVC1G07DBVR and compatible with most 5-pin logic buffers in SOT-23-5. However, functional equivalence requires verification: SN74LVC1G07DBVR is open-drain and lacks Ioff, while SN74LVC1G34DBVRG4 is push-pull with Ioff. Pinout alignment alone does not guarantee drop-in replacement without circuit review.
