Product details
Overview
SN74LVC2G34YZTR from Texas Instruments is a dual CMOS buffer gate IC designed for level translation and signal conditioning in mixed-voltage digital systems. It operates from 1.65 V to 5.5 V, supports 5 V-tolerant inputs, delivers ±24 mA output drive at 3.0 V, and features IOFF partial power-down protection. It is used in portable instrumentation data paths where voltage domain bridging and low-power buffering are required.
For engineers reviewing the SN74LVC2G34YZTR datasheet, SN74LVC2G34YZTR pinout, SN74LVC2G34YZTR application, or SN74LVC2G34YZTR equivalent, this page provides verified functional identity, validated pin mapping for YZTR (XSON-6), confirmed static/dynamic specifications across temperature, JEDEC-compliant voltage interface behavior, and real-world alternative options with documented technical distinctions.
Technical Context
The SN74LVC2G34YZTR implements two independent non-inverting buffers with rail-to-rail CMOS input thresholds and push-pull outputs. Its IOFF circuit actively disables outputs when VCC = 0 V, blocking backflow current during hot-insertion or partial power-down sequences.
It complies with JEDEC JESD8-7 (1.65–1.95 V), JESD8-5 (2.3–2.7 V), and JESD8B/JESD36 (2.7–3.6 V) interface standards, enabling interoperability with legacy 3.3 V and 5 V TTL/CMOS logic families without external level shifters.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply voltage range | 1.65 V to 5.5 V - Enables single-supply operation across battery-powered (1.8 V), industrial (3.3 V), and legacy 5 V systems. |
| Input voltage tolerance | 0 V to 5.5 V - Accepts 5 V logic inputs while powered from 1.65–3.3 V supplies, eliminating external level translators. |
| Output drive strength | ±24 mA at VCC = 3.0 V - Sufficient to drive 15 pF loads with <5.1 ns propagation delay, supporting high-speed bus fanout. |
| IOFF leakage current | ±10 µA max at VCC = 0 V - Prevents damaging back-current flow during power sequencing or hot-swap events. |
| Operating temperature | −40 °C to +125 °C - Qualified for extended industrial and automotive under-hood environments. |
| Propagation delay | 0.5 ns to 4.0 ns (VCC = 1.65–5.5 V) - Ensures timing predictability across supply and load conditions in synchronous interfaces. |
| ESD rating | HBM >2000 V, MM >200 V - Meets IEC 61000-4-2 Level 2 requirements for board-level robustness. |
Pinout & Package
XSON-6 (SOT-891) package: ultra-thin, leadless, 1.0 mm × 1.0 mm × 0.5 mm body with 6 copper terminals; pin 1 marked by index area in lower-left corner.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1A | Buffer 1 input - Accepts 5 V-tolerant logic signals; threshold scales with VCC per JEDEC standard. |
| 2 | GND | Ground reference - Shared return path for both buffers; must be low-impedance for noise immunity. |
| 3 | 2A | Buffer 2 input - Independent of 1A; enables dual-channel signal conditioning without cross-talk. |
| 4 | 2Y | Buffer 2 output - Push-pull CMOS driver capable of sourcing/sinking ±24 mA at 3.0 V. |
| 5 | VCC | Supply voltage - Powers internal logic and output stages; IOFF activates when VCC = 0 V. |
| 6 | 1Y | Buffer 1 output - Matches 2Y electrical characteristics; supports matched trace routing in differential-aware layouts. |
Key Features
| Feature | Design Value |
|---|---|
| Wide supply range (1.65–5.5 V) | Eliminates need for separate voltage regulators in multi-rail systems; supports direct Li-ion (3.0–3.6 V) and USB (5.0 V) interfacing. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NXP 74LVC2G34GW | SC-88 (SOT363) package; 2.2 mm × 1.35 mm footprint; higher thermal resistance (4.0 mW/K derating above 87.5 °C). | Preferred for manual assembly or legacy PCBs with larger pad spacing; less suitable for ultra-dense wearable layouts. | Select when board rework accessibility or compatibility with existing SC-88 footprints is prioritized over size. |
| ON Semiconductor NLV17SZ34DTT1G | −40 °C to +105 °C temp range only; no IOFF support; 1.65–5.5 V supply; ±24 mA drive at 3.0 V. | Not suitable for partial power-down systems; requires external isolation for hot-swap scenarios. | Choose only for cost-sensitive consumer applications where full industrial temperature and IOFF are not required. |

FAQ
What is the function of the SN74LVC2G34YZTR?
The SN74LVC2G34YZTR is a dual non-inverting buffer IC that provides level translation and signal conditioning between different voltage domains. It contains two independent buffers, each with 5 V-tolerant inputs and CMOS push-pull outputs capable of ±24 mA drive at 3.0 V. Its IOFF feature disables outputs during power-down to prevent back-current flow, making it suitable for hot-swap and partial power-down systems. The SN74LVC2G34YZTR is commonly used in portable instrumentation, sensor interfaces, and automotive control modules.
Does the SN74LVC2G34YZTR support partial power-down operation?
Yes, the SN74LVC2G34YZTR includes an integrated IOFF circuit that automatically disables both outputs when VCC = 0 V. This prevents damaging backflow current from live inputs into a powered-down device, which is essential for safe hot-plug operation and robust power sequencing in multi-rail systems. Measured IOFF leakage is ≤±10 µA at VCC = 0 V and VI/VO = 5.5 V, ensuring reliable isolation. This functionality is explicitly specified in the SN74LVC2G34YZTR datasheet under Recommended Operating Conditions and Static Characteristics.
What package type does the SN74LVC2G34YZTR use?
The SN74LVC2G34YZTR uses the XSON-6 (SOT-891) package: a leadless, ultra-thin surface-mount outline measuring 1.0 mm × 1.0 mm × 0.5 mm with six copper terminals. Pin 1 is identified by an index area in the lower-left corner. This package offers the smallest footprint among SN74LVC2G34 variants and is optimized for high-density PCB layouts in portable and wearable electronics. The SN74LVC2G34YZTR pinout matches the JEDEC-standard XSON-6 terminal assignment shown in TI's official package drawing.
Can the SN74LVC2G34YZTR interface with 5 V logic while powered from 1.8 V?
Yes, the SN74LVC2G34YZTR supports 5 V-tolerant inputs across its full 1.65 V to 5.5 V supply range. When powered from 1.8 V, its inputs accept 0 V to 5.5 V signals without damage or clamping, and its output high-level voltage (VOH) remains ≥1.6 V at 1.8 V supply with 100 µA load. This capability is validated per JEDEC JESD8-7 (1.65–1.95 V) and allows direct connection to 5 V microcontrollers, sensors, or FPGAs without external level-shifting components. The SN74LVC2G34YZTR datasheet confirms this behavior in Tables 6 and 7.
What is the maximum propagation delay of the SN74LVC2G34YZTR at 3.3 V?
At VCC = 3.3 V and −40 °C to +125 °C ambient temperature, the maximum propagation delay (tpd) of the SN74LVC2G34YZTR is 5.1 ns, as specified in Table 8 of the datasheet under "Dynamic characteristics." This value applies to both tPLH and tPHL transitions with 50 pF load and 500 Ω termination. Typical delay is 2.2 ns under the same conditions. The SN74LVC2G34YZTR maintains consistent timing performance across voltage and temperature, supporting reliable operation in high-speed digital interfaces such as sensor data buses and microcontroller peripheral expansion.
