Product details
Overview
74AVC1T45GW,125 from Nexperia is a single-bit dual-supply voltage level translator/transceiver with 3-state output, enabling bidirectional logic-level translation between mismatched I/O domains (e.g., 1.2 V ↔ 3.3 V). It features independent VCC(A) and VCC(B) supplies (0.8 V–3.6 V), DIR-controlled directionality, IOFF-enabled partial power-down, and operates across –40 °C to +125 °C. Used in mixed-voltage SoC interfacing, FPGA I/O bridging, and low-power sensor hub designs.
For engineers reviewing the 74AVC1T45GW,125 datasheet, 74AVC1T45GW,125 pinout, 74AVC1T45GW,125 application, or 74AVC1T45GW,125 equivalent, key selection criteria include dual-rail supply flexibility, sub-10 ns propagation delay at 1.8 V/3.3 V, IOFF leakage < ±1 μA during suspend mode, and TSSOP6 package compatibility with automated PCB assembly.
Technical Context
The device implements a bidirectional data path with direction controlled by a single DIR input referenced to VCC(A); HIGH enables A→B translation, LOW enables B→A. Both ports support dynamic 3-state control without external OE, eliminating bus contention risk when coordinated with system-level direction sequencing.
Its IOFF circuitry actively disables outputs and limits backflow current when either VCC(A) or VCC(B) is at GND, ensuring safe operation during power sequencing or partial shutdown-critical for battery-backed subsystems and hot-swap interfaces.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC(A) / VCC(B) Range | 0.8 V to 3.6 V each - supports translation between any two low-voltage rails (e.g., 1.2 V ↔ 1.8 V, 1.8 V ↔ 3.3 V) |
| Propagation Delay (A→B) | ≤ 7.1 ns at VCC(A)=3.3 V, VCC(B)=3.3 V - enables >140 MHz data rates in high-speed interconnects |
| IOFF Leakage Current | ±0.1 μA max at VCC(A)=0 V, VCC(B)=3.3 V - prevents damaging backfeed during asymmetric power-down |
| ESD Protection | HBM >8 kV, CDM >1 kV - robust enough for handling in uncontrolled manufacturing environments |
| Operating Temperature | –40 °C to +125 °C - qualified for under-hood automotive, industrial control, and telecom infrastructure |
| Power Dissipation Capacitance | 2 pF (A port, A→B direction) - minimizes dynamic switching power in battery-sensitive applications |
| Input Thresholds | VIL = 0.3×VCC(A), VIH = 0.65×VCC(A) - ensures reliable logic recognition across full supply range |
Pinout & Package
TSSOP6 (SOT363-2) package: plastic thin shrink small outline, 6-lead, 1.25 mm body width, lead pitch 0.65 mm, exposed pad not present.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | VCC(A) | Supply reference for port A and DIR input - sets logic thresholds and drive strength for A-side signals |
| 2 | GND | Common ground reference for both supply domains - mandatory for noise immunity and IOFF functionality |
| 3 | A | Bidirectional I/O port referenced to VCC(A) - connects to lower-voltage domain (e.g., MCU core I/O) |
| 4 | B | Bidirectional I/O port referenced to VCC(B) - connects to higher-voltage domain (e.g., legacy peripheral bus) |
| 5 | DIR | Direction control input (active-HIGH A→B, active-LOW B→A) - must be stable before data transitions to avoid metastability |
| 6 | VCC(B) | Supply reference for port B - independently configurable to match target interface voltage |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent supply rails | VCC(A) and VCC(B) each adjustable 0.8–3.6 V - eliminates need for external level-shifting components in heterogeneous voltage systems |
| IOFF partial power-down | Outputs disabled with < ±0.1 μA leakage when either VCC is at GND - enables safe integration into power-gated subsystems |
| Sub-10 ns propagation delay | 7.1 ns max (A→B) at 3.3 V/3.3 V - supports DDR-like timing margins in high-speed digital interfaces |
| Wide temperature qualification | Specified from –40 °C to +125 °C - meets AEC-Q100 Grade 0 stress requirements for automotive infotainment and ADAS modules |
| No external pull-ups required | Internal bus-hold circuitry absent; external termination needed only for open-drain compatibility - reduces BOM count in space-constrained layouts |
Applications
| Automotive Infotainment Interface | FPGA-to-MCU Communication |
|---|---|
Use Scenario: Connecting a 1.2 V automotive-grade MCU to a 3.3 V display controller in head-unit design. IC Role / Device Role / Timing Role: Bidirectional level translator managing SPI or UART signals with direction toggled per command frame.

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 |
|---|---|---|---|
| SN74AVC1T45DBVR | SOT-23-6 package; slightly higher ICC (24 μA vs. 16 μA typical); identical VCC range and timing | Less thermal mass than TSSOP6 - better for high-density layouts but lower power dissipation margin | Select for space-constrained boards where footprint size outweighs thermal performance needs |
| TXS0101DCKR | Auto-direction sensing (no DIR pin); higher VOL (0.8 V @ 12 mA); no IOFF support | Eliminates direction-control logic but introduces bus-contention risk during transitions | Select only for simple unidirectional or low-frequency bidirectional use cases without strict power-down safety requirements |
Compared with SN74AVC1T45DBVR and TXS0101DCKR, the 74AVC1T45GW,125 offers superior thermal performance in TSSOP6, guaranteed IOFF protection for asymmetric power sequencing, and tighter VOL/VOL specs critical for noise-immune 1.2 V interfaces.

FAQ
What is the maximum allowable voltage difference between VCC(A) and VCC(B)?
The datasheet permits any combination within 0.8 V to 3.6 V per rail, meaning ΔVCC can reach up to 2.8 V (e.g., VCC(A) = 0.8 V, VCC(B) = 3.6 V). No derating is required, and all timing and DC specs remain valid across this full differential range.
Can DIR be driven from a different voltage domain than VCC(A)?
No - DIR is strictly referenced to VCC(A), and its input thresholds scale with VCC(A) (VIH = 0.65×VCC(A)). Driving DIR from another supply violates the absolute maximum ratings and may cause undefined behavior or increased leakage.
Does the device support hot insertion when one supply is already active?
Yes - the IOFF circuit ensures that if VCC(A) is powered while VCC(B) is at 0 V, port B enters high-impedance state with leakage < ±0.1 μA, preventing backdrive into the unpowered domain. This satisfies hot-plug interoperability in modular systems.
Is there a minimum pulse width requirement for the DIR signal?
Yes - DIR must remain stable for ≥2.2 ns (min) before data transitions begin, based on worst-case tdis (DIR→B) of 2.2 ns at VCC(A)=1.2 V. Shorter pulses risk metastability or incomplete output disable/enable transitions.
