Product details
Overview
SN74LVC1G34 from Texas Instruments is a single non-inverting CMOS buffer gate designed for 1.65V to 5.5V VCC operation, delivering ±24mA output drive at 3.3V, 3.5ns max propagation delay (tpd) at 3.3V/CL=15pF, and Ioff support for live insertion and partial power-down. It serves as a level-translating signal buffer in portable audio interfaces and SSD control paths.
For engineers reviewing the SN74LVC1G34 datasheet, SN74LVC1G34 pinout, SN74LVC1G34 application, or SN74LVC1G34 equivalent, key selection criteria include its ultra-small DPW (X2SON-5) 0.8mm × 0.8mm package, 5.5V-tolerant inputs, down-translation capability, low 1μA max ICC, and JESD78 Class II latch-up compliance.
Technical Context
The SN74LVC1G34 implements a single positive-logic buffer (Y = A) using advanced CMOS process technology optimized for broad VCC range operation (1.65–5.5V). Its input structure accepts voltages up to 5.5V independent of VCC, enabling seamless level translation from higher-voltage logic domains into lower-VCC systems.
Ioff circuitry actively disables outputs during power-down, blocking back-drive current and supporting hot-plug functionality. The device operates across –40°C to 125°C for DBV/DCK/DRL packages and –40°C to 85°C for DPW, with thermal metrics confirming suitability for space-constrained, thermally demanding applications like embedded PC and tablet I/O expansion.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 1.65V to 5.5V - supports mixed-voltage system interfacing and battery-powered operation down to 1.65V |
| tpd (max) | 3.5ns at 3.3V, CL = 15pF - enables reliable signal buffering up to ~100MHz digital timing paths |
| IO Drive | ±24mA at 3.3V - sufficient to directly drive LEDs, multiple CMOS inputs, or moderate capacitive loads |
| ICC (max) | 1μA - ensures negligible quiescent power draw in always-on or low-power standby modes |
| Input Voltage Tolerance | Up to 5.5V - allows interfacing with 5V logic while powered from 1.8V or 3.3V rails without external level shifters |
| Ioff | ±10μA - prevents damaging current flow during partial power-down, critical for hot-swap and modular designs |
| ESD Rating (HBM) | ±2kV - exceeds JEDEC JS-001 requirements for robust handling in manufacturing and field service |
Pinout & Package
SN74LVC1G34DPWR uses the DPW (X2SON-5) package: 0.8mm × 0.8mm body size, 0.5mm pitch, 4 active terminals + 1 no-connect (N.C.) terminal. The package is lead-free, RoHS-compliant, and optimized for high-density PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (N.C.) | No internal connection | Must be left unconnected; no electrical function or thermal path |
| 2 (A) | Input | Single logic input accepting 0–5.5V; compatible with 1.65V–5.5V VCC and tolerant of overvoltage |
| 3 (GND) | Ground reference | Primary return path for output sink current and supply decoupling; must be low-impedance |
| 4 (Y) | Output | Non-inverting buffered output with ±24mA drive at 3.3V; supports capacitive loads ≤50pF |
| 5 (VCC) | Power supply | Supplies core logic and output drivers; requires local 0.1μF bypass capacitor placed adjacent to pin |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-small DPW package | 0.64mm² footprint (0.8mm × 0.8mm) - saves board area in portable SSDs, tablets, and wireless headsets |
| 5.5V-tolerant inputs | Accepts 0–5.5V regardless of VCC - eliminates need for discrete level translators in mixed-voltage I/O |
| Down-translation capability | Outputs swing rail-to-rail between GND and actual VCC - enables clean interface from 5V microcontrollers to 1.8V peripherals |
| Ioff protection | Active isolation when VCC = 0V - permits safe live insertion into powered backplanes or modular docking stations |
| High ESD robustness | HBM ±2kV, CDM ±1kV - meets industrial handling requirements without additional protection circuitry |
Applications
| Portable Audio Interface | Solid-State Drive (SSD) Control |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar buffer gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 74LVC1G17DPWR | Inverting buffer (Y = A̅); identical DPW package, VCC range, drive strength, and tpd | Requires logic inversion in signal path; unsuitable where polarity must be preserved | Select only if system-level logic design accommodates inversion - no change to PCB layout or thermal design needed |
| SN74LVC1G07DPWR | Open-drain output (no internal pull-up); same DPW package and VCC range but lacks push-pull drive | Requires external pull-up for HIGH-state signaling; incompatible with direct LED driving or rail-to-rail CMOS interfacing | Choose when wired-OR bus topology or voltage-level flexibility (e.g., 5V pull-up with 3.3V VCC) is required |
Compared with 74LVC1G17DPWR and SN74LVC1G07DPWR, SN74LVC1G34DPWR uniquely provides non-inverting push-pull output behavior in the same ultra-compact DPW package - essential for polarity-critical signal paths and direct load driving without external components.

FAQ
What is the maximum operating temperature for SN74LVC1G34DPWR?
The SN74LVC1G34DPWR has a specified operating free-air temperature range of –40°C to 85°C, as confirmed by TI's official datasheet SCES519O. This limit applies specifically to the DPW (X2SON-5) package variant due to its thermal resistance characteristics (RθJA = 340°C/W), and exceeds the –40°C to 125°C range supported by larger packages like DBV or DCK.
Does SN74LVC1G34DPWR support 5V logic inputs while powered from 1.8V?
Yes, SN74LVC1G34DPWR supports input voltages up to 5.5V regardless of VCC level - including when VCC = 1.8V. This 5V-tolerant input capability is explicitly documented in Section 5.3 (Recommended Operating Conditions) and enables direct interfacing between legacy 5V controllers and modern low-voltage subsystems without external level-shifting circuitry.
Can SN74LVC1G34DPWR drive an LED directly?
Yes, SN74LVC1G34DPWR can drive an LED directly: its ±24mA output drive at 3.3V (Section 5.3) and rail-to-rail output swing (VOL ≤ 0.55V at IOL = 24mA) provide sufficient current and voltage margin for standard indicator LEDs. TI's Application Note (Section 8.1) confirms this use case, noting suitability for "driving multiple outputs" including LEDs in portable audio devices.
What is the purpose of the N.C. pin on SN74LVC1G34DPWR?
Pin 1 of SN74LVC1G34DPWR is designated N.C. (No Connection) - it has no internal bond wire or silicon connection and serves no electrical or thermal function. Per TI's DPW package drawing and Pin Functions table (Section 4), this pin must remain unconnected on the PCB; routing or soldering to it may compromise mechanical reliability or cause unintended parasitic coupling.
How does Ioff functionality benefit system design with SN74LVC1G34DPWR?
Ioff in SN74LVC1G34DPWR disables output drivers when VCC = 0V, preventing back-current flow from live signal lines into a powered-down section. This feature is critical for modular docking stations, hot-pluggable SSDs, and multi-rail embedded PCs - allowing safe insertion/removal without risk of latch-up or damage, as verified by JESD78 Class II latch-up testing (>100mA).
