Product details
Overview
74AXP1T34GXH from Nexperia is a dual-supply translating buffer IC with independent input (VCCI) and output (VCCO) rails, enabling bidirectional voltage level translation between 0.7 V–2.75 V and 1.2 V–5.5 V domains. It features Schmitt-trigger inputs for noise immunity, IOFF circuitry for partial power-down protection, and operates across –40 °C to +85 °C. Used in mixed-voltage I/O interfacing between low-power microcontrollers and higher-voltage peripherals.
For engineers reviewing the 74AXP1T34GXH datasheet, 74AXP1T34GXH pinout, 74AXP1T34GXH application, or 74AXP1T34GXH equivalent, key selection criteria include verified dual-rail supply ranges, IOFF-enabled isolation during power sequencing, sub-1 ns transition time, <0.6 pF input capacitance, and X2SON5 package compatibility with high-density PCB layouts.
Technical Context
This device implements a single-channel unidirectional buffer with input referenced to VCCI and output referenced to VCCO, supporting true voltage translation without direction control pins. Its Schmitt-trigger input threshold scales with VCCI (e.g., VIH = 0.65×VCCI at 1.1–1.95 V), ensuring robust signal integrity across wide input voltage swings.
The IOFF circuit actively disables the output when either supply is near 0 V, limiting backflow current to ≤±0.5 μA - critical for hot-swap and partial-power-down systems. Static current remains below 0.5 μA (ICCI) and 1.8 μA (ICCO) at 85 °C, enabling ultra-low-power operation in battery-backed subsystems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCCI Range | 0.7 V to 2.75 V: Enables interface with sub-1 V logic families (e.g., 0.8 V FPGA I/O) and legacy 1.2/1.8 V cores. |
| VCCO Range | 1.2 V to 5.5 V: Supports translation to 1.8 V, 2.5 V, 3.3 V, and 5 V peripheral buses without external level shifters. |
| Propagation Delay | 1.6–22 ns (typ): Measured A→Y at VCCI=2.5 V/VCCO=3.3 V, enabling use in ≤50 MHz digital control paths. |
| Input Capacitance | 0.6 pF (typ): Minimizes loading on high-impedance or high-speed source drivers (e.g., sensor outputs, clock distribution). |
| IOFF Leakage | ≤±0.5 μA at 85 °C: Prevents damaging back-current during asymmetric power-down sequences in multi-rail systems. |
| ESD Rating | HBM >2000 V, CDM >1000 V: Sufficient for handling in standard assembly environments without special ESD controls. |
| Operating Temp | –40 °C to +85 °C: Qualified for industrial automation, automotive body electronics, and outdoor IoT edge nodes. |
Pinout & Package
X2SON5 package (SOT1226-3): 0.8 mm × 0.8 mm × 0.32 mm thermal-enhanced no-lead outline with 5 terminals, optimized for space-constrained and thermally demanding applications.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | VCCI | Input-side supply rail: References all input thresholds and powers internal input stage; must be stable before A transitions. |
| 2 | A | Single data input: Accepts voltages up to 2.75 V regardless of VCCI; Schmitt-trigger action tolerates slow edges ≥200 ns/V. |
| 3 | GND | Digital ground reference: Shared return path for both VCCI and VCCO supplies; requires low-inductance connection. |
| 4 | Y | Output buffer: Drives load referenced to VCCO; output voltage swing is 0 V to VCCO with rail-to-rail capability. |
| 5 | VCCO | Output-side supply rail: Sets output logic high level and powers output driver; enables translation to higher-voltage domains. |
Key Features
| Feature | Design Value |
|---|---|
| Dual-rail translation | Independent VCCI (0.7–2.75 V) and VCCO (1.2–5.5 V) allow seamless interconnection of disparate logic families without external components. |
| IOFF partial power-down | Automatically disables Y output when VCCI or VCCO ≈ 0 V, preventing destructive back-current flow in live-backplane or hot-plug systems. |
| Ultra-low input capacitance | 0.6 pF typical minimizes signal distortion and timing skew when driving long traces or high-frequency sources like crystal oscillators. |
| Schmitt-trigger input | Hysteresis ≥100 mV at VCCI = 1.2 V ensures reliable switching despite noisy or slow-rising signals from mechanical switches or analog comparators. |
| JEDEC-compliant interfaces | Fully compliant with JESD8-12A.01 through JESD12-6 standards, guaranteeing interoperability with certified 1.1 V to 5.5 V logic families. |
Applications
| Industrial Sensor Interface | Low-Power MCU I/O Expansion |
|---|---|
|
Use Scenario: Interfacing a 0.8 V-output MEMS accelerometer to a 3.3 V ADC input in a battery-powered condition monitoring node. IC Role / Device Role / Timing Role: Translates logic levels while maintaining signal integrity across supply domains; Schmitt input rejects EMI-induced glitches on sensor lines.

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-supply buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TXS0101DCKR | Single-channel, 1.2–3.6 V VCCA / 1.65–5.5 V VCCB; no Schmitt input; IOFF supported. | Lacks Schmitt-trigger input - unsuitable for noisy or slow-rising sensor signals without external filtering. | Select when interfacing clean CMOS outputs and strict 1.2 V minimum VCCA is not required. |
| SN74AVC1T45DBVR | Direction-controlled dual-supply buffer (DIR pin required); 1.2–3.6 V VCCA / 1.2–3.6 V VCCB; no IOFF. | Requires external direction control logic and cannot safely isolate during asymmetric power loss. | Choose only if bidirectional data flow is needed and system-level power sequencing is fully controlled. |
Compared with TXS0101DCKR and SN74AVC1T45DBVR, the 74AXP1T34GXH uniquely combines Schmitt-trigger noise immunity, true IOFF isolation, and extended low-VCCI support (down to 0.7 V), making it optimal for ultra-low-voltage sensor hubs and fail-safe industrial I/O.

FAQ
Can 74AXP1T34GXH translate from 5.5 V to 0.7 V?
No. The device supports unidirectional translation only: input referenced to VCCI (0.7–2.75 V) and output referenced to VCCO (1.2–5.5 V). It cannot accept 5.5 V on A or drive 0.7 V on Y. Input voltage must not exceed 2.75 V, and output swing is bounded by VCCO, not VCCI.
Is the X2SON5 package (SOT1226-3) compatible with standard reflow profiles?
Yes. The SOT1226-3 package is qualified for IPC/JEDEC J-STD-020D moisture sensitivity level 1 and supports peak reflow temperatures up to 260 °C. Its thermal-enhanced construction allows full-rated power dissipation (250 mW) with linear derating above 67 °C ambient.
Does the IOFF feature activate automatically when VCCI = 0 V but VCCO = 3.3 V?
Yes. IOFF activates whenever VCCI ≤ 0.1 V or VCCO ≤ 0.1 V, forcing Y into high-impedance state regardless of A state. Measured IOFF leakage is ≤±0.5 μA under these conditions, protecting downstream 3.3 V circuitry from back-current.
What is the maximum capacitive load the Y output can drive while maintaining 1.6 ns transition time?
At VCCI = 2.5 V and VCCO = 3.3 V, the 74AXP1T34GXH maintains ≤1.6 ns transition time (tt) with CL ≤ 15 pF. Beyond 15 pF, transition time increases linearly - e.g., 30 pF yields ~2.2 ns - due to CO = 1.8 pF and driver strength limitations.
