Product details
Overview
74AXP1T34GNH 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 74AXP1T34GNH datasheet, 74AXP1T34GNH pinout, 74AXP1T34GNH application, or 74AXP1T34GNH equivalent, this device supports precise voltage domain bridging in space-constrained portable electronics, battery-powered sensors, and multi-rail FPGA/ASIC I/O expansion where static/dynamic power minimization and rail-to-rail compatibility are critical selection criteria.
Technical Context
The 74AXP1T34GNH implements a single-channel unidirectional buffer with input referenced to VCCI and output referenced to VCCO, supporting true dual-supply operation without internal level-shifting circuitry. Its Schmitt-trigger input ensures robust signal integrity with slow-edge signals, while IOFF disables the output during power-down to prevent backflow current.
It complies with JEDEC standards JESD8-12A.01 through JESD12-6 across multiple voltage bands and delivers ultra-low static current (≤0.5 μA ICCI at 85 °C) and dynamic capacitance (CI = 0.6 pF, CO = 1.8 pF), making it suitable for always-on subsystems and battery-backed interfaces.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCCI Range | 0.7 V to 2.75 V - Enables interface with sub-1V logic (e.g., ARM Cortex-M0+ I/O) and 1.2V/1.8V cores. |
| VCCO Range | 1.2 V to 5.5 V - Supports legacy 3.3V/5V peripherals, GPIO expanders, and industrial I/O modules. |
| Propagation Delay | 1.6 ns to 152 ns - Varies with supply combination; minimum 1.6 ns at VCCI=2.5V/VCCO=5.0V enables high-speed data handshaking. |
| IOFF Leakage | ±0.5 μA max - Ensures safe isolation when either supply is powered down, preventing bus contention or damage. |
| Input Capacitance | 0.6 pF typical - Minimizes loading on driving source, preserving signal rise/fall times in high-frequency traces. |
| ESD Rating | HBM >2000 V, CDM >1000 V - Meets industrial-grade ESD robustness without external protection components. |
Pinout & Package
XSON6 package (SOT1115): extremely thin small outline, no leads, 6 terminals, body size 0.9 × 1.0 × 0.35 mm - optimized for high-density PCB layouts and automated assembly in wearables and IoT edge nodes.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - VCCI | Input supply reference | Powers input stage and sets logic threshold; must be stable before A transitions. |
| 2 - A | Data input | Schmitt-triggered; accepts voltages up to 2.75 V regardless of VCCI setting. |
| 3 - GND | Ground reference | Common return for both supplies; mandatory connection for IOFF functionality and noise rejection. |
| 4 - Y | Data output | CMOS-compatible output referenced to VCCO; drives loads up to ±12 mA at 3.3V. |
| 5 - n.c. | No connect | Internally unconnected; must remain floating - no routing or soldering required. |
| 6 - VCCO | Output supply reference | Sets output voltage swing and drive strength; decoupling capacitor required near pin. |
Key Features
| Feature | Design Value |
|---|---|
| Dual-supply translation | Independent VCCI (0.7–2.75 V) and VCCO (1.2–5.5 V) enable interoperability across three generations of logic families. |
| IOFF partial power-down | Automatically disables Y output when either VCCI or VCCO = 0 V, eliminating backfeed risk in hot-swap or sleep-mode systems. |
| Ultra-low static power | ICCI ≤ 0.5 μA and ICCO ≤ 1.8 μA at 85 °C - extends battery life in always-listening sensor nodes. |
| Schmitt-trigger input | Hysteresis ≥ 100 mV typical - rejects noise on long traces or unshielded cables without external RC filtering. |
| JEDEC-compliant I/O | Validated against JESD8-12A.01 through JESD12-6 - guarantees interoperability with certified 1.2V/1.8V/2.5V/3.3V/5V ASICs and FPGAs. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-supply buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TXS0102DCUR | 2-channel, auto-direction sensing, higher ICCO (10 μA), larger X2SON8 package (1.35 × 2.0 mm) | Requires no direction control signal but consumes ~20× more static current than 74AXP1T34GNH | Prefer when bidirectional data flow is needed; avoid if ultra-low quiescent current is mandatory. |
| SN74LVC1T34DBVR | Single-supply only (1.65–5.5 V), no VCCI/VCCO separation, lower ESD (HBM 2000 V same, but no CDM spec) | Lacks true dual-rail translation - cannot interface sub-1.65 V logic like 0.8 V IoT MCUs | Select only for single-rail systems; reject for mixed-voltage designs requiring sub-1.2 V input support. |
Compared with TXS0102DCUR and SN74LVC1T34DBVR, the 74AXP1T34GNH uniquely combines sub-1V input compatibility, IOFF-enabled power sequencing safety, and 0.6 pF input capacitance - making it the sole choice for space-constrained, battery-sensitive, multi-rail embedded systems demanding guaranteed rail independence.

FAQ
Can 74AXP1T34GNH translate from 5.5 V down to 0.7 V?
No. The device only supports unidirectional translation: 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 always tied to VCCO.
Does the n.c. pin on SOT1115 require grounding or termination?
No. Pin 5 is internally unconnected and must remain floating - no PCB trace, solder, or pull-up/down resistor should be applied. Routing to ground or VCC would violate the package specification and may cause functional failure or increased leakage.
What is the maximum capacitive load the Y output can drive reliably?
The Y output is characterized up to 120 pF load capacitance per Figure 7–12. At 3.3 V VCCO and 25 °C, propagation delay increases from 1.7 ns (CL = 0 pF) to 7.1 ns (CL = 120 pF). For timing-critical paths, keep CL ≤ 30 pF to maintain sub-3 ns delay.
How does IOFF behave when only VCCI is powered and VCCO = 0 V?
When VCCO = 0 V (or ≤ 0.1 V) and VCCI is active, IOFF activates automatically: Y enters high-impedance state with ≤±0.5 μA off-state current. This prevents current injection into a powered-down 3.3 V or 5 V rail, satisfying IEC 61000-4-2 system-level ESD safety requirements.
