Product details
Overview
74LVC2G34GF/S500132 from NXP Semiconductors is a dual CMOS buffer gate in XSON6 (SOT891) package, operating from 1.65 V to 5.5 V supply, with 5 V-tolerant inputs and ±24 mA output drive at 3.0 V. It supports mixed-voltage interfacing between 3.3 V and 5 V logic domains and implements IOFF circuitry for partial power-down protection in battery-powered or hot-swap systems.
For engineers reviewing the 74LVC2G34GF/S500132 datasheet, 74LVC2G34GF/S500132 pinout, 74LVC2G34GF/S500132 application, or 74LVC2G34GF/S500132 equivalent, key selection criteria include its 1.0 mm × 1.0 mm × 0.5 mm XSON6 footprint, −40 °C to +125 °C temperature rating, IOFF-enabled backflow current suppression, propagation delay as low as 0.5 ns at 4.5–5.5 V, and JEDEC-compliant voltage-level interoperability across 1.65–5.5 V operation.
Technical Context
The 74LVC2G34GF/S500132 implements two independent non-inverting buffers with rail-to-rail CMOS input thresholds and push-pull outputs. Its IOFF feature actively disables outputs when VCC = 0 V, blocking destructive current flow during power sequencing or standby modes.
Input voltage tolerance up to 5.5 V-regardless of VCC level-enables direct connection to legacy 5 V TTL or LVTTL sources without level-shifting. Static characteristics are guaranteed over full industrial temperature range (−40 °C to +125 °C), with propagation delays specified per supply voltage band (e.g., 0.5–4.0 ns at 4.5–5.5 V).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply voltage | 1.65 V to 5.5 V - supports single-rail operation across 1.8 V, 2.5 V, 3.3 V, and 5 V logic families |
| Input voltage tolerance | Up to 5.5 V - allows direct interface with 5 V TTL outputs without external level shifters |
| Output drive strength | ±24 mA at VCC = 3.0 V - sufficient to drive multiple LVC loads or moderate capacitive bus lines |
| Propagation delay | 0.5 ns (min) to 4.0 ns (max) at 4.5–5.5 V - enables high-speed signal buffering in timing-critical paths |
| IOFF leakage current | ±10 µA max at VCC = 0 V - prevents backflow current during system power-down sequences |
| Operating temperature | −40 °C to +125 °C - qualified for under-hood, industrial control, and extended-temperature embedded applications |
| ESD protection | HBM > 2000 V, MM > 200 V - meets IEC 61000-4-2 Level 2 robustness requirements |
Pinout & Package
XSON6 (SOT891) plastic extremely thin small outline package; no leads; 6 terminals; body dimensions 1.0 mm × 1.0 mm × 0.5 mm; pin 1 indicator located on lower left corner below marking code.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1A | Data input for first buffer - accepts 0 V to 5.5 V signals regardless of VCC level |
| 2 | GND | Ground reference - must be connected to system 0 V plane for stable logic operation |
| 3 | 2A | Data input for second buffer - electrically isolated from 1A; supports independent signal routing |
| 4 | 2Y | Data output for second buffer - active-high, non-inverting, capable of sourcing/sinking ±24 mA |
| 5 | VCC | Positive supply - powers both buffers; IOFF activates automatically when VCC = 0 V |
| 6 | 1Y | Data output for first buffer - matches 2Y in drive capability and timing behavior |
Key Features
| Feature | Design Value |
|---|---|
| Wide supply range | 1.65 V to 5.5 V - eliminates need for separate voltage rails in multi-supply systems |
| 5 V tolerant inputs | VI up to 5.5 V with VCC as low as 1.65 V - enables backward compatibility with legacy 5 V logic |
| IOFF power-down protection | Outputs disabled and leakage limited to ±10 µA when VCC = 0 V - prevents damage during hot insertion or partial shutdown |
| High noise immunity | Typical VIH/VIL margins > 30 % of VCC across all supply ranges - resists EMI-induced glitches in noisy environments |
| JEDEC compliance | JESD8-7 (1.65–1.95 V), JESD8-5 (2.3–2.7 V), JESD8B/JESD36 (2.7–3.6 V) - ensures interoperability with standardized logic families |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC2G34DBVR | TSSOP-6 (SOT23-6) package; 2.5 mm × 1.25 mm footprint; identical electrical specs and IOFF functionality | Requires larger PCB area and different reflow profile due to gull-wing leads; better suited for prototyping or manual assembly | Select when leaded package preferred for testability or hand-soldering; not drop-in compatible with SOT891 layout |
| 74AUP2G34GSF | Lower static current (ICC < 0.5 µA typical); wider VCC range (0.8 V to 3.6 V); no 5 V input tolerance | Not suitable for 5 V logic interfacing; optimized for ultra-low-power battery applications below 3.3 V | Choose only for sub-1 V to 3.3 V systems requiring nanowatt standby; incompatible with 5 V signal domains |
Compared with SN74LVC2G34DBVR, the 74LVC2G34GF/S500132 offers 60 % smaller board area and superior thermal performance in high-density layouts; versus 74AUP2G34GSF, it trades ultra-low ICC for essential 5 V tolerance and broader supply flexibility required in mixed-voltage industrial designs.

FAQ
What is the maximum input voltage the 74LVC2G34GF/S500132 can tolerate?
The 74LVC2G34GF/S500132 supports input voltages up to 5.5 V regardless of VCC level, enabling direct connection to 5 V TTL or LVTTL outputs without external level-shifting circuitry. This specification is guaranteed across the full operating temperature range (−40 °C to +125 °C) and applies to both 1A and 2A pins. Input clamping current remains within safe limits (±50 mA) when this rating is observed.
Does the 74LVC2G34GF/S500132 support partial power-down operation?
Yes, the 74LVC2G34GF/S500132 integrates IOFF circuitry that automatically disables both outputs when VCC = 0 V, limiting backflow current to ±10 µA maximum. This protects upstream and downstream components during hot-swap, battery removal, or system sleep states. The feature operates independently of input signal states and requires no external control.
What is the propagation delay of the 74LVC2G34GF/S500132 at 3.3 V supply?
At VCC = 3.3 V and ambient temperature of 25 °C, the typical propagation delay (tpd) of the 74LVC2G34GF/S500132 is 2.2 ns, with a maximum of 4.1 ns over −40 °C to +85 °C and 5.1 ns over −40 °C to +125 °C. These values apply to both 1A→1Y and 2A→2Y paths under standard load conditions (CL = 50 pF, RL = 500 Ω).
Which package type does the 74LVC2G34GF/S500132 use?
The 74LVC2G34GF/S500132 uses the XSON6 package (JEDEC designation SOT891): a leadless, surface-mount package measuring 1.0 mm × 1.0 mm × 0.5 mm with six copper terminals. Pin 1 is marked by a corner notch on the lower-left side of the body, and the package is optimized for high-density PCB layouts and automated reflow assembly.
Is the 74LVC2G34GF/S500132 compliant with JEDEC standards?
Yes, the 74LVC2G34GF/S500132 complies with multiple JEDEC standards: JESD8-7 (1.65–1.95 V), JESD8-5 (2.3–2.7 V), and JESD8B/JESD36 (2.7–3.6 V). These certifications confirm interoperability with industry-standard logic families across its full supply voltage range and validate input threshold behavior under defined voltage bands.
