Product details
Overview
74LVC2G126GD/S470 from Nexperia is a dual 3-state bus buffer/line driver with independent output enable (nOE) control per channel, designed for level translation between 1.65 V–5.5 V logic domains. It features Schmitt-trigger inputs for noise immunity, ±24 mA drive capability at 3.0 V, and IOFF circuitry enabling partial power-down operation in mixed-voltage systems such as industrial I/O expansion and FPGA interface bridging.
For engineers reviewing the 74LVC2G126GD/S470 datasheet, 74LVC2G126GD/S470 pinout, 74LVC2G126GD/S470 application, or 74LVC2G126GD/S470 equivalent, this device supports voltage-level translation, high-noise-margin signal buffering, and hot-swap-safe 3-state control - critical for embedded controller peripheral interfacing, sensor hub data routing, and legacy-to-modern logic domain bridging.
Technical Context
The 74LVC2G126GD/S470 implements two independent non-inverting buffers, each with active-HIGH output enable (1OE, 2OE) and Schmitt-trigger input thresholds. Its IOFF functionality disables outputs and blocks backflow current when VCC = 0 V, satisfying JEDEC JESD78 requirements for partial power-down integrity.
It operates across 1.65 V–5.5 V supply range with input tolerance up to 5.5 V, enabling direct connection to both 3.3 V and 5 V TTL-compatible sources. Propagation delay ranges from 0.5 ns (VCC = 5.5 V) to 12.5 ns (VCC = 1.65 V), and disable time (tdis) is specified down to 0.5 ns at 5.5 V - supporting high-speed digital control paths in compact PCB layouts.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.65 V to 5.5 V - enables single-supply operation across 1.8 V, 2.5 V, 3.3 V, and 5 V logic families |
| Output Drive Strength | ±24 mA at VCC = 3.0 V - sufficient to drive 50 Ω transmission lines or multiple CMOS loads without external buffering |
| Input Voltage Tolerance | Up to 5.5 V - allows safe interfacing with 5 V microcontrollers or legacy peripherals while powered from 3.3 V or lower |
| IOFF Leakage Current | ±2 μA max at VCC = 0 V - prevents damaging backfeed current during system power sequencing or hot-swap events |
| Propagation Delay (tpd) | 0.5 ns to 12.5 ns - scales predictably with VCC, supporting timing-critical enable/disable control in real-time I/O subsystems |
| Operating Temperature | −40 °C to +125 °C - qualified for extended industrial and automotive under-hood environments |
| ESD Protection | HBM > 2000 V, CDM > 1000 V - robust handling during board assembly and field service without additional protection circuitry |
Pinout & Package
XSON8 ultra-thin no-lead package (SOT1089), 1.35 mm × 1.0 mm × 0.5 mm body, 0.4 mm pitch, wettable flank terminals for automated optical inspection (AOI) and reliable solder-joint quality in high-density designs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1OE | Active-HIGH output enable for Channel 1 - drives 1Y into high-impedance state when LOW |
| 2 | VCC | Main supply rail - powers internal logic and output drivers; decoupling capacitor required within 2 mm |
| 3 | 1A | Data input for Channel 1 - Schmitt-trigger input accepts slow-rising signals and rejects noise spikes |
| 4 | 2OE | Active-HIGH output enable for Channel 2 - independent control enables asymmetric bus arbitration |
| 5 | 2Y | Data output for Channel 2 - 3-state capable; sinks or sources up to ±24 mA depending on VCC and load |
| 6 | 1Y | Data output for Channel 1 - electrically isolated from 2Y; supports bidirectional bus partitioning |
| 7 | GND | Reference ground - must be low-inductance connection to minimize switching noise coupling |
| 8 | 2A | Data input for Channel 2 - identical electrical behavior to 1A; supports parallel or staggered data routing |
Key Features
| Feature | Design Value |
|---|---|
| Wide VCC range (1.65–5.5 V) | Eliminates need for external level shifters in multi-rail systems - reduces BOM count and layout area |
| IOFF partial power-down | Prevents back-current flow when VCC is off - essential for PCIe add-in cards, modular I/O boards, and hot-pluggable subsystems |
| Schmitt-trigger inputs | Provides ≥0.3 V hysteresis - tolerates noisy or slow-switching signals from mechanical switches, sensors, or long traces |
| 8-terminal XSON8 (SOT1089) | 0.5 mm profile and 1.35 × 1.0 mm footprint - fits beneath 0402 passives and enables <1.2 mm board thickness in wearables and IoT edge nodes |
| JESD8-compliant interfaces | Validated against JEDEC standards JESD8-7, -5, and -B/JESD36 - ensures interoperability with certified memory, MCU, and ASIC I/Os |
Applications
| Industrial PLC I/O Expansion | FPGA-to-Microcontroller Interface |
|---|---|
Use Scenario: Isolating and translating GPIO signals between a 3.3 V FPGA bank and 5 V industrial analog/digital I/O modules. IC Role / Device Role / Timing Role: Dual-channel unidirectional buffer providing voltage translation and 3-state isolation during configuration or fault recovery. Use Value: Enables direct connection without discrete level shifters; IOFF prevents backfeed into FPGA during module hot-swap or power cycling. |
Use Scenario: Routing control signals (e.g., reset, chip select, interrupt) between a 1.8 V FPGA and a 3.3 V ARM Cortex-M7 microcontroller. IC Role / Device Role / Timing Role: Low-latency, rail-to-rail compatible buffer ensuring clean signal edges and deterministic timing margins. Use Value: Sub-1 ns propagation delay at 3.3 V preserves setup/hold timing; Schmitt inputs reject noise from shared PCB ground planes. |
| Automotive Body Control Module | Medical Sensor Hub Interface |
Use Scenario: Buffering LIN bus wake-up signals and door-lock actuator commands in a 12 V vehicle subsystem powered by local 3.3 V LDO. IC Role / Device Role / Timing Role: Level translator and noise-immune driver for low-duty-cycle control lines operating across temperature extremes. Use Value: −40 °C to +125 °C rating ensures reliability; 5.5 V-tolerant inputs accept LIN transceiver outputs directly without clamping diodes. |
Use Scenario: Aggregating digital outputs from multiple low-power biosensors (e.g., pulse oximeter, ECG front-end) into a central MCU with mixed-voltage I/O banks. IC Role / Device Role / Timing Role: Signal conditioner and bus isolator that maintains signal integrity while enabling selective channel shutdown. Use Value: Independent OE pins allow per-sensor power gating; ±24 mA drive supports capacitive loads of long flex-cable interconnects. |
Equivalent & Alternatives

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC2G126DBVR | TI part in SOT-23-8 package; identical logic function but larger 2.92 × 1.62 mm footprint and 1.45 mm height | Lacks XSON8's ultra-low profile; less suitable for space-constrained wearable or implantable devices | Select when legacy SOT-23 rework compatibility or TI ecosystem alignment is prioritized over miniaturization |
| 74LVC2G126GT,115 | Nexperia XSON8 variant (SOT833-1); same 1 × 1.95 × 0.5 mm body but 0.5 mm wider - impacts fine-pitch routing density | Marginally larger pad layout; requires updated stencil design but shares same thermal and electrical specs | Choose for higher-volume production where SOT833-1's broader industry adoption simplifies sourcing and test fixture reuse |

FAQ
Does 74LVC2G126GD/S470 support true bidirectional data flow?
No. The 74LVC2G126GD/S470 is a dual unidirectional buffer: data flows only from A inputs to Y outputs. Each channel has independent 3-state control via nOE, but there is no internal direction control or bus turnaround logic. For bidirectional applications, use dedicated transceivers like 74LVC2T45 or 74LVC245 variants.
Can 74LVC2G126GD/S470 be used with 1.2 V logic inputs?
No. Minimum recommended VCC is 1.65 V, and VIH minimum is 0.65×VCC (≥1.07 V at 1.65 V). A 1.2 V input falls below guaranteed recognition threshold and may cause metastability or incorrect output states. For 1.2 V interfaces, consider LVC1G125 or specialized ultra-low-voltage translators.
What is the maximum capacitive load this device can drive reliably?
At VCC = 3.3 V and 24 mA drive, the device supports ≤30 pF load capacitance while maintaining specified tpd and VOL/VOH margins. Driving >50 pF increases propagation delay nonlinearly and risks overshoot; for heavier loads, add series termination or use a driver with higher current rating like 74LVC2G241.
Is the SOT1089 package RoHS and REACH compliant?
Yes. The 74LVC2G126GD/S470 in SOT1089 (XSON8) meets RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006, with lead-free matte tin terminal finish and halogen-free molding compound - verified per Nexperia's material declarations and IPC-1752A reporting.
