Product details
Overview
AXP1T34GSH from Nexperia is a single-bit, dual-supply translating buffer IC designed for voltage-level translation between independent logic domains. It features one Schmitt-trigger input (A), one CMOS output (Y), and separate input (VCCI) and output (VCCO) supply pins, each supporting 0.9 V to 5.5 V. With propagation delay as low as 14.5 ns at 3.3 V/1.2 V, IOFF-enabled partial power-down, and −40 °C to +125 °C operation, it serves in mixed-voltage FPGA I/O bridging and processor peripheral interfacing.
For engineers reviewing the AXP1T34GSH datasheet, AXP1T34GSH pinout, AXP1T34GSH application, or AXP1T34GSH equivalent, this page delivers verified electrical specs, package-validated pin functions, real-world use cases across industrial control and automotive infotainment, and two confirmed drop-in alternatives with documented voltage and timing differences.
Technical Context
The AXP1T34GSH implements a dual-rail architecture where the input stage is referenced solely to VCCI and the output stage to VCCO-enabling true bidirectional voltage translation without level-shifter biasing or direction control. Its patented glitch suppression circuitry ensures no output transients during asynchronous VCCI/VCCO power-up/down transitions up to 5.5 V/s slew rate.
Schmitt-trigger input thresholds scale with VCCI (e.g., VIH = 0.7×VCCI, VIL = 0.3×VCCI), while output drive strength is defined per VCCO (VOH ≥ VCCO − 0.1 V at light load; VOL ≤ 0.8 V at 12 mA). The IOFF circuit disables Y and isolates backflow current when either supply drops to GND, enabling safe hot-swap and suspend-mode operation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCCI Range | 0.9 V to 5.5 V: supports translation from sub-1 V logic (e.g., LPDDR4 I/O) up to 5 V legacy systems |
| VCCO Range | 0.9 V to 5.5 V: enables output compatibility with 1.2 V ASIC cores, 1.8 V memory, or 3.3 V microcontrollers |
| tpd (A→Y) | 14.5 ns min @ VCCI=1.2 V, VCCO=3.3 V: meets setup/hold timing for 33 MHz parallel interfaces |
| IOFF Leakage | ±2 µA max @ −40 °C to +125 °C: prevents >100 µW standby power in powered-down subsystems |
| Input Capacitance | 1.5 pF typical: minimizes loading on high-speed clock or data lines driving multiple buffers |
| ESD Rating | HBM >2000 V, CDM >1000 V: survives handling and board-level ESD events without latch-up |
| Operating Temp | −40 °C to +125 °C: qualified for under-hood automotive and industrial motor-control environments |
Pinout & Package
AXP1T34GSH is packaged in SOT1226-3 (X2SON5): 5-terminal, leadless, thermal-enhanced plastic package measuring 0.8 mm × 0.8 mm × 0.32 mm with wettable flanks for automated optical inspection.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCCI | Input supply reference | Biases input Schmitt trigger and internal logic; determines VIH/VIL thresholds |
| A | Data input | Single-ended digital signal input with hysteresis; accepts 0–5.5 V regardless of VCCI |
| GND | Ground reference | Common return path for both supplies; required for proper IOFF and ESD performance |
| Y | Data output | CMOS-compatible output referenced to VCCO; drives loads up to ±25 mA |
| VCCO | Output supply reference | Sets VOH/VOL levels and output drive strength; independent of VCCI |
Key Features
| Feature | Design Value |
|---|---|
| Dual-supply translation | Independent VCCI/VCCO rails enable seamless interface between 1.2 V SoC and 3.3 V sensor hub without external resistors or direction pins |
| Glitch-free power sequencing | Patented circuitry eliminates output glitches during VCCI/VCCO transitions from 20 mV/μs to 5.5 V/s-critical for reliable boot-up in multi-rail systems |
| IOFF partial power-down | Output enters high-Z state with <±2 µA leakage when VCCI or VCCO = GND, preventing backfeed into powered-down domains |
| Schmitt-trigger input | 200 mV typical hysteresis at 1.2 V VCCI improves noise margin for slow-rising signals from mechanical switches or long PCB traces |
| Low dynamic capacitance | CI = 1.5 pF and CO = 3.8 pF minimize signal distortion and crosstalk in dense routing on high-speed PCBs |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-supply buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NXP NX3V1T34GM | Same pinout (SOT886), identical VCCI/VCCO range, but lacks IOFF and has higher ICCO (1.5 µA vs 1.0 µA max) | Not suitable for partial power-down designs requiring zero backfeed current | Select when IOFF is unnecessary and cost is primary; verify thermal derating for 125 °C operation |
| Texas Instruments SN74AVC1T34DBVR | Same function, but only supports VCCI/VCCO = 1.2–3.6 V; no 5 V tolerance on inputs or outputs | Cannot replace AXP1T34GSH in 5 V legacy system interfaces or mixed 0.9–5.5 V rail designs | Choose only for 1.2–3.3 V-only applications; requires redesign if 5 V signals are present |
Compared with NX3V1T34GM and SN74AVC1T34DBVR, the AXP1T34GSH uniquely combines full 0.9–5.5 V dual-rail support, guaranteed IOFF, and −40 °C to +125 °C qualification-making it the sole option for automotive-grade, hot-swap-capable, wide-voltage industrial interfaces.

FAQ
What is the maximum allowable slew rate for VCCI and VCCO transitions without causing output glitches?
The AXP1T34GSH guarantees glitch-free operation for supply transitions ranging from 20 mV/μs up to 5.5 V/s, as validated by Nexperia's patented circuitry. This covers all realistic power-up/down profiles in industrial and automotive systems, including fast-switching DC-DC converters and slow-battery ramp scenarios.
Can the AXP1T34GSH translate from 5.0 V input to 1.2 V output while maintaining timing integrity?
Yes: the input accepts voltages up to 5.5 V regardless of VCCI, and with VCCI = 5.0 V and VCCO = 1.2 V, tpd remains ≤32 ns (max) over −40 °C to +125 °C. VOH is guaranteed ≥1.1 V and VOL ≤0.35 V at 1.5 mA load, satisfying 1.2 V LVCMOS logic thresholds.
Does the IOFF feature require external control signals or is it fully automatic?
IOFF is fully automatic and requires no external enable/disable signals. When either VCCI or VCCO drops to GND, the output Y immediately enters high-impedance state with leakage <±2 µA-verified across full temperature range. No pull-up/down resistors or firmware intervention are needed.
Is the AXP1T34GSH pin-compatible with other Nexperia single-bit translators like the AXP1T34GW?
No: AXP1T34GSH uses SOT1226-3 (5-pin X2SON5), whereas AXP1T34GW uses SOT353-1 (5-pin TSSOP5). Though both have identical pin numbering (VCCI-A-GND-Y-VCCO), their footprints, thermal pads, and solder reflow profiles differ significantly-requiring separate PCB land patterns and assembly validation.
