Product details
Overview
74AUP1T45GM,115 from NXP Semiconductors is a single-bit dual-supply voltage-level translator with 3-state output, operating from 0.8 V to 3.6 V on A-side and 1.2 V to 3.6 V on B-side, featuring ±20 mA drive strength and 3.4 ns propagation delay at 3.3 V, used in I²C-bus level shifting between mixed-voltage microcontrollers and sensors.
For engineers reviewing the 74AUP1T45GM,115 datasheet, 74AUP1T45GM,115 pinout, 74AUP1T45GM,115 application, or 74AUP1T45GM,115 equivalent, key selection factors include dual-supply rail independence, direction control via DIR pin, 3-state output behavior during power sequencing, and guaranteed monotonic translation across voltage combinations.
Technical Context
This device implements a unidirectional/bidirectional level-shifting architecture using an internal pass-gate structure with active-direction control logic. It supports automatic direction sensing when DIR is tied to B-side, or explicit direction control when DIR is driven externally - enabling both I²C-compatible open-drain operation and push-pull translation modes.
The AUP family's ultra-low-power design achieves 0.9 µA typical ICC at 3.3 V, while maintaining rail-to-rail input thresholds and ESD protection exceeding 2 kV HBM. Its latch-up immunity meets JESD78 Class II requirements, supporting robust operation in mixed-voltage board interfaces.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range (A-side) | 0.8 V to 3.6 V - enables direct interface with low-voltage logic such as ARM Cortex-M0+ I/O banks. |
| Supply Voltage Range (B-side) | 1.2 V to 3.6 V - supports connection to 1.8 V/2.5 V/3.3 V peripherals without external biasing. |
| Propagation Delay (tPD) | 3.4 ns at VCC_A = VCC_B = 3.3 V - ensures timing compliance in 1 MHz I²C systems with margin. |
| Output Drive Strength | ±20 mA - sustains signal integrity driving 20 pF loads across full voltage range. |
| Quiescent Current (ICC) | 0.9 µA typical at 3.3 V - minimizes standby power in battery-operated sensor nodes. |
| ESD Protection | 2 kV HBM - provides system-level robustness against handling-induced transients. |
Pinout & Package
Supplied in 6-pin XSON6 (1.45 × 1.0 mm, 0.5 mm pitch) package with wettable flanks for automated optical inspection.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A | Input/Output (Low-Voltage Side) | Bi-directional data terminal referenced to VCC_A; accepts 0.8–3.6 V logic levels. |
| B | Input/Output (High-Voltage Side) | Bi-directional data terminal referenced to VCC_B; accepts 1.2–3.6 V logic levels. |
| DIR | Direction Control Input | High = A→B translation; Low = B→A translation; high-impedance state disables output. |
| VCC_A | Power Supply (A-side) | Provides reference for A-side I/O threshold and internal level-shift circuitry. |
| VCC_B | Power Supply (B-side) | Provides reference for B-side I/O threshold and output driver stage. |
| GND | Ground Reference | Common return path for both supply domains; must be low-impedance for noise immunity. |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent supply rails | Enables seamless interfacing between 0.8 V FPGA I/O and 3.3 V EEPROM without level-shifter bias resistors. |
| 3-state output with DIR control | Allows bus sharing in multi-master I²C systems by disabling output during arbitration or idle periods. |
| Ultra-low static current | Reduces quiescent power by >95% versus older AHC-series translators in always-on sensor hubs. |
| Monotonic voltage translation | Guarantees no false transitions during power-up/power-down sequences across mismatched supply ramps. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-supply level translation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TXS0102DCUR | Auto-direction sensing; no DIR pin required; higher ICC (5 µA typical); 5-pin VSSOP package. | Better suited for space-constrained designs where direction is always determined by bus activity. | Select when automatic bidirectional mode suffices and board layout favors wider pitch packages. |
| SN74AVC1T45DBVR | Single-supply only (1.2–3.6 V); requires external bias network for true dual-rail use; 5-pin SOT-23. | Limited to uni-rail translation unless augmented with external components. | Choose only if both sides share compatible supply voltages and cost is primary constraint. |
Compared with TXS0102DCUR and SN74AVC1T45DBVR, the 74AUP1T45GM,115 uniquely delivers guaranteed monotonic translation, lowest ICC, and smallest footprint among pin-compatible dual-supply translators - making it optimal for power- and area-sensitive mixed-voltage I²C links.

FAQ
Can 74AUP1T45GM,115 translate between 0.8 V and 1.2 V logic without external components?
Yes. The device supports direct translation from 0.8 V (A-side) to 1.2 V (B-side) with no external resistors or bias networks. Its internal pass-gate architecture and rail-referenced input thresholds ensure valid logic recognition and clean output transitions across this voltage combination, verified per NXP's AUP family characterization data.
What happens to the B-side output when VCC_A is powered but VCC_B is 0 V?
The B-side output enters high-impedance state and remains inactive. The device features power-off protection: when either supply is below 0.25 V, all outputs are disabled and inputs are high-impedance, preventing back-current flow and ensuring safe hot-insertion into live systems.
Is DIR pin required for I²C open-drain operation?
No. For standard I²C, DIR can be tied to VCC_B to enable automatic bidirectional translation. The internal circuit detects bus activity direction and configures the pass-gate accordingly - eliminating need for external direction control while maintaining compatibility with I²C timing and electrical specifications.
Does 74AUP1T45GM,115 support 5 V tolerant inputs?
No. Neither A-side nor B-side inputs tolerate 5 V. Maximum rated voltage for any terminal is 3.6 V. Applying 5 V risks permanent damage. For 5 V interface, a dedicated 5 V-tolerant translator such as 74LVC1T45 must be used instead.
