Product details
Overview
74AVC2T45DP from Nexperia is a dual-bit, dual-supply voltage level translator/transceiver enabling bidirectional logic-level translation between 0.8 V and 3.6 V domains. It features independent VCC(A) and VCC(B) supplies, DIR-controlled data direction (A↔B), 3-state outputs, and IOFF circuitry for partial power-down protection. Used in mixed-voltage SoC interconnects, such as translating between a 1.8 V FPGA I/O and a 3.3 V peripheral bus.
For engineers reviewing the 74AVC2T45DP datasheet, 74AVC2T45DP pinout, 74AVC2T45DP application, or 74AVC2T45DP equivalent, key selection criteria include bidirectional translation capability, IOFF-enabled power-down safety, Suspend mode behavior during rail loss, and TSSOP8 package compatibility with high-density PCB layouts.
Technical Context
The device implements a dual-rail transceiver architecture with DIR input referenced to VCC(A), while ports 1A/2A are referenced to VCC(A) and ports 1B/2B to VCC(B). Direction control is synchronous: DIR = HIGH enables A→B transmission; DIR = LOW enables B→A transmission.
Suspend mode activates when either VCC(A) or VCC(B) = GND, forcing both ports into high-impedance OFF-state. The IOFF circuit prevents backflow current during partial power-down, meeting JEDEC JESD78 Class II latch-up immunity (>100 mA).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply range VCC(A) | 0.8 V to 3.6 V - supports direct interface to 0.8 V, 1.2 V, 1.5 V, 1.8 V, 2.5 V, and 3.3 V logic families |
| Supply range VCC(B) | 0.8 V to 3.6 V - independently configurable for asymmetric voltage translation (e.g., 1.2 V ↔ 3.3 V) |
| Max data rate | 500 Mbit/s - achievable when translating between 1.8 V and 3.3 V domains under typical conditions |
| Propagation delay (A→B) | ≤9.2 ns at VCC(A)=VCC(B)=3.3 V - ensures timing-critical bidirectional bus operation with sub-10 ns latency |
| IOFF leakage | ±1 μA max at VCC(A)=0 V, VCC(B)=3.6 V - limits backflow current during safe partial power-down |
| Operating temperature | −40 °C to +125 °C - qualified for automotive under-hood and industrial control applications |
| ESD rating (HBM) | >8000 V - exceeds JEDEC JS-001 Class 3B, enabling robust handling in manufacturing and field environments |
Pinout & Package
TSSOP8 package (SOT505-2): plastic thin shrink small outline, 8 leads, 3 mm body width, 0.5 mm lead length, pin 1 indicator below marking code 'B45'.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | VCC(A) | Supply rail for A-side I/O and DIR input - defines logic thresholds for pins 1A, 2A, and DIR |
| 2 | 1A | Data I/O port A channel 1 - bidirectional, referenced to VCC(A), supports 0.8–3.6 V signaling |
| 3 | 2A | Data I/O port A channel 2 - identical electrical behavior to 1A; enables dual-signal translation |
| 4 | GND | Common reference ground - must be connected before any supply rail per power-up recommendation |
| 5 | DIR | Direction control input - HIGH enables 1A/2A → 1B/2B; LOW enables reverse flow; referenced to VCC(A) |
| 6 | 2B | Data I/O port B channel 2 - bidirectional, referenced to VCC(B), supports 0.8–3.6 V signaling |
| 7 | 1B | Data I/O port B channel 1 - electrically isolated from A-side; enables independent domain translation |
| 8 | VCC(B) | Supply rail for B-side I/O - defines logic thresholds for pins 1B and 2B; fully independent of VCC(A) |
Key Features
| Feature | Design Value |
|---|---|
| Dual-supply translation | Enables simultaneous interfacing of two independent voltage domains without level-shifting resistors or external biasing |
| IOFF partial power-down | Automatically disables outputs and blocks damaging backflow current when either VCC rail is unpowered |
| Suspend mode | Guarantees high-impedance state on both A and B ports if VCC(A) or VCC(B) drops to GND - prevents bus contention |
| JEDEC compliance | Meets JESD8-12 through JESD8-B standards across 0.8–3.6 V range - ensures interoperability with industry-standard logic families |
| Low noise switching | Overshoot/undershoot <10 % of VCC - reduces EMI and signal integrity risk in high-speed mixed-voltage buses |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-supply voltage translation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74AVC2T45DCUR | VSSOP8 package (2.3 mm width); 100 mW lower Ptot derating threshold; identical electrical specs and pinout mapping | Better suited for ultra-dense layouts where 0.7 mm narrower body improves routing clearance | Select when board space is constrained and thermal margin above 99 °C is not required |
| TXS0102DCUR | Auto-direction sensing (no DIR pin); higher VOL (0.8 V @ 2 mA) at 1.8 V; lacks IOFF and Suspend mode | Requires external pull-up/down on data lines; unsuitable for partial power-down or rail-loss scenarios | Choose only for simple unidirectional or auto-bidirectional links where power sequencing is guaranteed |
Compared with SN74AVC2T45DCUR and TXS0102DCUR, the 74AVC2T45DP offers superior system-level robustness via explicit DIR control, guaranteed Suspend behavior, and IOFF protection-critical for automotive and industrial applications with unpredictable power sequencing.

FAQ
What is the minimum recommended supply voltage for reliable operation of 74AVC2T45DP?
The device is fully specified from 0.8 V to 3.6 V on both VCC(A) and VCC(B) rails. At 0.8 V, static parameters including VOH (≥0.69 V) and VOL (≤0.07 V) meet specification, and dynamic performance remains functional at reduced data rates. Operation below 0.8 V is not characterized and may result in undefined logic states or increased leakage.
How does the DIR input behave during power-up sequences?
DIR is referenced solely to VCC(A), so it remains invalid until VCC(A) reaches ≥0.3 × VCC(A) (per VIH/VIL specs). The device requires GND to be applied first; no specific VCC(A)/VCC(B) sequencing is mandated. Once powered, DIR controls direction immediately - no internal reset or initialization delay is required.
Can 74AVC2T45DP translate between 0.8 V and 2.5 V in both directions simultaneously?
Yes - the dual-supply architecture allows independent configuration: VCC(A) = 0.8 V and VCC(B) = 2.5 V. DIR determines direction: HIGH enables 0.8 V signals (1A/2A) to drive 2.5 V outputs (1B/2B); LOW enables reverse. Propagation delay is ≤12.0 ns (B→A) and ≤12.2 ns (A→B) under these conditions.
Is external termination required for 500 Mbit/s operation?
No external series termination is required for basic functionality, but controlled-impedance PCB routing (e.g., 50 Ω single-ended) is recommended to maintain signal integrity at 500 Mbit/s. The device's low output capacitance (CI/O ≤4.0 pF) and <10 % overshoot support clean edges without added components in most compact layouts.
