Product details
Overview
SN74LVC2G34YZPR from Texas Instruments is a dual non-inverting buffer gate in a 6-pin DSBGA package, designed for 1.65-V to 5.5-V VCC operation. It performs Y = A logic with ±24-mA output drive at 3.3 V, 4.1-ns max propagation delay, and Ioff support for partial-power-down applications. It enables voltage translation from 5.5-V inputs down to the VCC level in space-constrained portable audio and SSD interfaces.
For engineers reviewing the SN74LVC2G34YZPR datasheet, SN74LVC2G34YZPR pinout, SN74LVC2G34YZPR application, or SN74LVC2G34YZPR equivalent, key selection criteria include its 1.41 mm × 0.91 mm NanoFree™ DSBGA footprint, 5.5-V tolerant inputs, Ioff-enabled live insertion capability, and guaranteed operation from –40°C to +85°C ambient.
Technical Context
The SN74LVC2G34YZPR implements two independent CMOS buffer gates with rail-to-rail output swing and balanced rise/fall times. Its Ioff circuitry actively disables outputs when VCC = 0 V, blocking backflow current and enabling hot-plug compatibility.
Input tolerance up to 5.5 V allows interfacing with higher-voltage logic domains while operating from low VCC (e.g., 1.8 V), making it suitable for mixed-supply signal conditioning. The device exhibits typical output ground bounce (VOLP) < 0.8 V and output undershoot (VOHV) > 2 V at 3.3 V, confirming robust noise margin under fast switching.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 1.65 V to 5.5 V - supports single-supply operation across legacy and modern low-voltage systems |
| Max tpd | 4.1 ns at 3.3 V - enables reliable timing in ≤100-MHz digital signal paths |

| 2A | Input 2 | Independent non-inverting buffer input; electrically isolated from 1A path |
| 2Y | Output 2 | Buffered replica of 2A; fully decoupled from 1Y with separate output stage |
| GND | Ground | Reference return for all internal logic and output stages; must be low-impedance |
| VCC | Power Supply | Primary supply for logic core and output drivers; bypass capacitor required per layout guidelines |
Key Features
| Feature | Design Value |
|---|---|
| NanoFree™ DSBGA packaging | 1.41 mm × 0.91 mm footprint eliminates leadframe, reduces parasitic inductance, and enables direct die-mount on PCB |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC2G34DCKR | SC70-6 package (2.00 mm × 1.25 mm); same electrical specs and Ioff support | Larger footprint but easier manual soldering and probe access; thermal resistance RθJA = 259°C/W vs. 123°C/W for YZP | Select DCKR for prototyping or low-volume assembly where DSBGA rework is impractical |
| SN74LVC2G34DBVR | SOT-23-6 package (2.90 mm × 1.60 mm); identical logic function and voltage ratings | Higher board area use and lower thermal performance (RθJA = 165°C/W); compatible with standard pick-and-place feeders | Choose DBVR for cost-sensitive production where automated assembly infrastructure favors SOT-23 |

FAQ
What is the maximum operating temperature for SN74LVC2G34YZPR?
The SN74LVC2G34YZPR is rated for operation from –40°C to +85°C ambient temperature. This range is defined by its DSBGA (YZP) package qualification and applies to all recommended VCC conditions. Operation beyond +85°C is not guaranteed and may violate absolute maximum junction temperature limits.
Does SN74LVC2G34YZPR support hot-plug insertion?
Yes, SN74LVC2G34YZPR supports hot-plug insertion via its Ioff circuitry. When VCC = 0 V, the outputs are disabled and input/output leakage remains below ±10 µA, preventing damaging back-current flow during live insertion into powered systems.
Can SN74LVC2G34YZPR translate 5-V input signals to a 1.8-V supply domain?
Yes, SN74LVC2G34YZPR accepts input voltages up to 5.5 V while operating from VCC = 1.8 V, enabling direct down-translation without external level shifters. Its output will swing rail-to-rail between GND and 1.8 V, preserving logic thresholds for downstream 1.8-V receivers.
What is the recommended bypass capacitor for SN74LVC2G34YZPR?
Texas Instruments recommends a 0.1-µF ceramic capacitor placed as close as possible to the VCC ball of SN74LVC2G34YZPR. For systems with multiple logic devices, paralleling a 1-µF capacitor improves low-frequency noise rejection while the 0.1-µF handles high-frequency transients.
Is SN74LVC2G34YZPR pin-compatible with other SN74LVC2G34 variants?
No-SN74LVC2G34YZPR uses a 6-ball DSBGA (YZP) layout with Pin 1 in Quadrant Q1, while SN74LVC2G34DBVR (SOT-23) and SN74LVC2G34DCKR (SC70) have different pinouts and physical footprints. Electrical functionality is identical, but PCB layout is not interchangeable.
