Product details
Overview
SN74LVC1G34 from Texas Instruments is a single non-inverting CMOS buffer gate designed for 1.65V–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 conditioner 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) package (0.8mm × 0.8mm), 5.5V-tolerant inputs, down-translation capability to VCC, and JESD78 Class II latch-up compliance.
Technical Context
The SN74LVC1G34 implements a single positive-logic buffer (Y = A) with rail-to-rail CMOS output swing and input voltage tolerance up to 5.5V independent of VCC. Its Ioff circuitry actively disables outputs during power-down, blocking back-drive current and enabling hot-plug capability.
It operates across –40°C to 125°C (depending on package), supports CL ≤ 50pF loads, and maintains specified tpd and drive strength over full VCC (1.65V–5.5V) and temperature ranges - confirmed in Tables 5.6–5.8 and Section 5.3 of SCES519O.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 1.65V to 5.5V - enables direct interface with 1.8V, 2.5V, 3.3V, and 5V logic domains |
| Max tpd | 3.5ns at 3.3V/CL=15pF - supports >100MHz signal buffering with timing margin |
| Output Drive | ±24mA at 3.3V - sufficient to drive multiple CMOS inputs or low-current LEDs without external buffers |
| Ioff | <±10μA at 5.5V - ensures safe isolation during partial power-down and live insertion |
| Input Voltage Tolerance | Up to 5.5V - allows interfacing with higher-voltage controllers while powered from lower VCC |
| ESD Rating | ±2kV HBM - meets industrial-grade robustness per JESD22-A114A |
| Quiescent Current | 1μA max ICC - enables ultra-low-power standby in battery-operated devices |
Pinout & Package
SN74LVC1G34 YZPR uses the DSBGA-5 (YZP) package: 1.75mm × 1.25mm body, 0.4mm pitch, 5-ball array with no internal connection on Ball 1 (DNU). Pin mapping is validated per TI mechanical drawing SLAS999B.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Ball 1 (A1) | No connect (DNU) | Unused ball; must be left unconnected or grounded per layout guidelines |
| Ball 2 (B1) | Input (A) | CMOS-compatible input accepting 0–5.5V; drives internal buffer stage |
| Ball 3 (C1) | Ground (GND) | Primary reference for all I/O and internal logic; requires low-impedance PCB return path |
| Ball 4 (C2) | Output (Y) | Push-pull CMOS output capable of sourcing/sinking ±24mA at 3.3V |
| Ball 5 (A2) | Supply (VCC) | Power pin for 1.65–5.5V operation; requires local 0.1μF bypass capacitor |
Key Features
| Feature | Design Value |
|---|---|
| 5.5V-tolerant inputs | Enables direct connection to legacy 5V controllers without level shifters when VCC ≥ 1.65V |
| Ioff protection | Prevents damaging back-current flow during system power sequencing or hot-swap events |
| Ultra-small YZP package | 1.75mm × 1.25mm footprint saves board space in portable SSDs and tablet I/O expansion |
| Down-translation capability | Accepts 5V inputs while operating from 1.8V/2.5V/3.3V rails - simplifies mixed-voltage domain bridging |
| JESD78 Class II latch-up | Exceeds 100mA immunity - ensures reliability in noisy industrial and telecom power environments |

Equivalent & Alternatives
The following parts are listed as comparable options for similar buffer gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC1G17YZPR | Schmitt-trigger input (hysteresis ~0.2V), same YZP package and VCC range | Better noise immunity for slow-rising or noisy control lines (e.g., mechanical switch debouncing) | Select when input signal edges are slow or subject to EMI; not suitable for high-speed data buffering due to added propagation delay variation |
| 74LVC1G34GW,125 | NXP SC-70-5 package (2.0mm × 2.1mm); identical logic function and electrical specs per datasheet 74LVC1G34 | Larger footprint but wider global distributor availability and longer production lifetime visibility | Choose for supply chain diversification where board space permits; same functional behavior and pinout compatibility confirmed in NXP documentation |
Compared with SN74LVC1G34, SN74LVC1G17YZPR adds input hysteresis at the cost of deterministic timing, while 74LVC1G34GW,125 offers identical functionality in a more widely stocked SC-70 package - enabling design continuity without layout revision.

FAQ
What is the maximum operating temperature for SN74LVC1G34 in the YZP package?
The SN74LVC1G34 in YZP (DSBGA-5) package is rated for –40°C to +85°C ambient operating temperature, as specified in Section 5.3 of the SCES519O datasheet. This differs from packages like DBV or DCK, which support up to +125°C.
Does SN74LVC1G34 support 5V logic inputs while powered from 1.8V?
Yes. SN74LVC1G34 accepts input voltages up to 5.5V regardless of VCC, enabling true down-translation - e.g., a 5V microcontroller can drive SN74LVC1G34 powered from 1.8V, with output referenced to 1.8V.
Can SN74LVC1G34 drive an LED directly?
Yes. With ±24mA output drive at 3.3V and VOL ≤ 0.55V at 24mA, SN74LVC1G34 can directly sink/source typical indicator LEDs (e.g., 2–20mA, 1.8–3.3V forward voltage) without external current-limiting resistors in many cases - though series resistance is recommended for precise current control.
Is the Ball 1 (A1) pin on SN74LVC1G34 YZPR required to be connected?
No. Ball 1 (A1) is designated "DNU" (Do Not Use) in the YZP package per TI's SLAS999B drawing. It has no internal connection and must remain unconnected or optionally grounded for mechanical stability - never tied to VCC or active signals.
What is the minimum load capacitance requirement for SN74LVC1G34 timing specifications?
SN74LVC1G34 switching characteristics (e.g., tpd = 3.5ns) are guaranteed with CL = 15pF per Figure 6-1 and Table 5.6. While it functions with lower capacitance, timing parameters are not characterized below 15pF; designs requiring tight skew control should maintain ≥15pF load or validate performance empirically.
