Product details
Overview
74AUP1T34GM,132 from Nexperia is a single-channel dual-supply level-translating buffer with independent VCC(A) and VCC(Y) rails (1.1 V to 3.6 V each), Schmitt-trigger inputs for noise immunity, IOFF-enabled partial power-down protection, and guaranteed operation from –40 °C to +125 °C in the XSON6 (SOT886) package. It enables voltage translation between disparate logic domains in ultra-low-power IoT sensors and battery-powered microcontroller peripherals.
For engineers reviewing the 74AUP1T34GM,132 datasheet, 74AUP1T34GM,132 pinout, 74AUP1T34GM,132 application, or 74AUP1T34GM,132 equivalent, this device is selected for its sub-1 µA static ICC, dual-rail flexibility, IOFF backflow prevention, and validated performance across industrial temperature extremes - critical when interfacing 1.2 V I²C peripherals with 3.3 V host controllers.
Technical Context
The 74AUP1T34GM implements a non-inverting buffer with input referenced to VCC(A) and output referenced to VCC(Y), enabling bidirectional voltage translation without external components. Its Schmitt-trigger input threshold scales with VCC(A), ensuring robust switching despite slow-rising signals or high-impedance source conditions.
IOFF circuitry actively disables the output stage when either supply is near 0 V, limiting off-state leakage to ±0.75 µA and preventing destructive current flow during mixed-voltage power sequencing - a requirement in modern multi-rail embedded systems with staggered power-up.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range (A/Y) | 1.1 V to 3.6 V per rail - supports translation between 1.2 V, 1.8 V, 2.5 V, and 3.3 V logic domains |
| ICC (max) | 1.4 µA at +125 °C - enables always-on sensor interface nodes with multi-year battery life |
| IOFF Leakage | ±0.75 µA - prevents backfeed current during partial power-down of host MCU or peripheral |
| tpd (typ) | 3.1 ns at VCC(A)=3.3 V, VCC(Y)=3.3 V, CL=5 pF - sufficient for I²C, SPI, and GPIO signal routing |
| Operating Temp | –40 °C to +125 °C - qualified for under-hood automotive, industrial motor control, and outdoor edge devices |
| ESD Rating | HBM >5000 V, CDM >1000 V - withstands handling and board-level ESD events without protection diodes |
| Input Threshold | VIH = 2.0 V min at VCC(A)=3.0–3.6 V; VIL = 0.9 V max - ensures clean logic recognition across full VCC range |
Pinout & Package
XSON6 plastic extremely thin small outline package (SOT886); no leads; 6 terminals; body size 1.0 × 1.45 × 0.5 mm; wettable flanks not present; thermal pad absent.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A | Data input | Single logic input referenced to VCC(A); accepts 0–3.6 V with Schmitt-trigger hysteresis |
| VCC(A) | Input-side supply | Powers input stage and defines VIH/VIL thresholds; decoupling required within 1 cm |
| GND | Ground reference | Common return for both supply rails; must be low-impedance and shared with system ground plane |
| n.c. | No-connect terminal | Internally unconnected; left floating - no PCB trace or solder mask opening needed |
| VCC(Y) | Output-side supply | Powers output driver and sets VOH/VOL levels; independent of VCC(A) for true level shifting |
| Y | Data output | Non-inverting buffered output referenced to VCC(Y); drives loads up to ±20 mA |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent supplies | VCC(A) and VCC(Y) operate independently from 1.1 V to 3.6 V - eliminates need for external level shifters in mixed-voltage SoC interfaces |
| IOFF partial power-down | Output disabled with <±0.75 µA leakage when either VCC is 0 V - prevents bus contention during MCU sleep or hot-swap events |
| Schmitt-trigger input | Hysteresis ≥0.3×VCC(A) - rejects noise on long traces or high-impedance sensor outputs without external RC filtering |
| Ultra-low ICC | Max 1.4 µA at +125 °C - reduces system quiescent power by >90% vs. standard AUP buffers in always-on monitoring circuits |
| Industrial temp grade | Specified from –40 °C to +125 °C - supports deployment in engine control units, smart meters, and factory automation without derating |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar level-translating buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC1T34DBVR | Single-supply only (1.65–5.5 V); no dual-rail translation; higher ICC (10 µA typ) | Cannot translate between dissimilar rails (e.g., 1.2 V → 3.3 V); lacks IOFF | Select only when both sides share same VCC and partial power-down is unnecessary |
| TXB0101DCKR | Auto-direction sensing; higher propagation delay (12 ns typ); larger X2SON6 package (1.45 × 1.0 mm) | Supports bidirectional data but adds complexity for unidirectional use cases; requires external enable control | Prefer only for true bidirectional protocols like I²C; overkill for simple GPIO translation |
Compared with SN74LVC1T34DBVR and TXB0101DCKR, the 74AUP1T34GM,132 uniquely delivers true dual-rail translation with sub-1.5 µA ICC and guaranteed IOFF behavior - making it optimal for space-constrained, ultra-low-power unidirectional interfaces where supply independence and leakage control are mandatory.

FAQ
Can 74AUP1T34GM,132 translate from 3.3 V to 1.2 V?
No - the 74AUP1T34GM,132 is unidirectional: input A is referenced to VCC(A), output Y to VCC(Y). To translate 3.3 V logic down to 1.2 V, VCC(A) must be 3.3 V and VCC(Y) set to 1.2 V. The device does not support reverse-direction translation or automatic direction sensing.
Is the n.c. pin on SOT886 required to be grounded or left floating?
The n.c. (no-connect) pin on the SOT886 package is internally unconnected and must be left floating - no PCB trace, solder mask opening, or grounding is permitted. Connecting it risks internal shorting or undefined behavior per Nexperia's package specification.
Does the IOFF feature activate automatically when VCC(A) or VCC(Y) drops below a threshold?
Yes - IOFF activates whenever either VCC(A) or VCC(Y) falls below approximately 0.2 V, disabling the output driver and limiting leakage to ±0.75 µA. This occurs without external control signals and is inherent to the silicon design, ensuring fail-safe behavior during power sequencing.
What is the maximum capacitive load the Y output can drive reliably?
The Y output is characterized up to 30 pF load capacitance with guaranteed tpd and VOH/VOL performance across all VCC combinations and temperatures. Driving >30 pF may increase propagation delay nonlinearly and degrade noise margins; for heavier loads, add series termination or consider a buffer with higher drive strength.
