Product details
Overview
74AVC2T45GN,115 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), and IOFF circuitry for partial power-down protection. Used in mixed-voltage SoC interconnects, such as translating between 1.2 V FPGA I/O and 3.3 V peripheral buses.
For engineers reviewing the 74AVC2T45GN,115 datasheet, 74AVC2T45GN,115 pinout, 74AVC2T45GN,115 application, or 74AVC2T45GN,115 equivalent, key selection criteria include bidirectional translation capability, IOFF-enabled suspend mode, 8-pin XSON8 package compatibility, and support for -40 °C to +125 °C industrial operation.
Technical Context
The device implements a dual-supply transceiver architecture with separate voltage references: pins 1A, 2A, and DIR are referenced to VCC(A); pins 1B and 2B to VCC(B). Direction control is asynchronous and unidirectional per cycle-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, satisfying JEDEC JESD78 Class II latch-up immunity (>100 mA).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply range VCC(A)/VCC(B) | 0.8 V to 3.6 V each - enables translation across 0.8 V, 1.2 V, 1.5 V, 1.8 V, 2.5 V, and 3.3 V nodes |
| Max data rate | 500 Mbit/s (1.8 V ↔ 3.3 V) - supports high-speed interface bridging without external timing control |
| Propagation delay (A→B) | Min 1.0 ns / Max 9.9 ns at -40 °C to +125 °C - ensures deterministic timing in real-time bus arbitration |
| IOFF leakage (VCC=0 V) | ±35 μA max - guarantees safe isolation during hot-swap or sleep-mode sequencing |
| ESD rating (HBM) | >8000 V - meets IEC 61000-4-2 Level 4 for robust board-level ESD immunity |
| Operating temperature | -40 °C to +125 °C - qualified for under-hood automotive and industrial control applications |
| Input capacitance | 1.0 pF (DIR), 4.0 pF (I/O) - minimizes signal loading on high-frequency clock/data lines |
Pinout & Package
XSON8 package (SOT1116): 1.2 × 1.0 × 0.35 mm, no leads, 8 terminals, thermal pad not present, pin 1 indicator below marking code "B5".
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC(A) | Supply A reference | Powers and sets logic threshold for DIR, 1A, 2A - must be stable before asserting DIR or data |
| 1A, 2A | Data port A | Bidirectional I/O referenced to VCC(A); driven by or drives A-side logic (e.g., 1.2 V core) |
| GND | Ground reference | Common 0 V return for both supply domains - mandatory first connection during power sequencing |
| DIR | Direction control | Asynchronous active-HIGH signal referenced to VCC(A); controls A→B (H) or B→A (L) data flow |
| 2B, 1B | Data port B | Bidirectional I/O referenced to VCC(B); interfaces to B-side logic (e.g., 3.3 V sensor bus) |
| VCC(B) | Supply B reference | Powers and sets logic threshold for 1B, 2B - independent of VCC(A), enabling true dual-rail operation |
Key Features
| Feature | Design Value |
|---|---|
| Dual-supply translation | Independent 0.8–3.6 V rails per port enable interoperability between disparate low-voltage logic families |
| IOFF partial power-down | Automatic output disable when either VCC is at GND prevents back-current damage during staggered power sequencing |
| Suspend mode | Both ports enter high-Z when VCC(A)=GND or VCC(B)=GND - eliminates bus contention in sleep states |
| JEDEC compliance | Validated across JESD8-12 through JESD8-B - ensures interoperability with industry-standard voltage-tiered interfaces |
| Low dynamic power | CPD = 1–17 pF depending on rail combination - reduces switching power in battery-powered edge devices |
Applications
| Industrial PLC I/O Modules | Automotive ADAS Sensor Hub |

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 |
|---|---|---|---|
| TXS0202DCUR | Auto-direction sensing (no DIR pin); lower max VCC = 3.6 V; higher ICC = 25 μA typical | Eliminates DIR control logic but adds input hysteresis - unsuitable where explicit direction timing control is required | Select when system lacks dedicated DIR line and tolerates ~3 ns longer enable time |
| SN74AVC4T245PWR | Quad-channel (4-bit); TSSOP16 package; wider VCC range (1.2–3.6 V); no 0.8 V support | Higher channel density suits parallel bus translation but occupies 3× PCB area vs. XSON8 | Select for 4-bit parallel interfaces where space permits and 0.8 V operation is unnecessary |
Compared with TXS0202DCUR and SN74AVC4T245PWR, the 74AVC2T45GN,115 uniquely delivers 0.8 V compatibility, minimal 1.2 mm² XSON8 footprint, and deterministic DIR-controlled direction switching - critical for resource-constrained, mixed-voltage embedded designs requiring precise bus arbitration.

FAQ
What is the minimum valid VCC(A) and VCC(B) voltage for functional operation?
The 74AVC2T45GN,115 operates down to 0.8 V on both VCC(A) and VCC(B) rails, with guaranteed static and dynamic performance including VIH/VIL thresholds, propagation delay, and IOFF behavior across the full -40 °C to +125 °C range. Operation below 0.8 V is not characterized and may result in undefined logic states or increased leakage.
Can VCC(A) and VCC(B) be powered from different sources with independent ramp rates?
Yes - the device supports independent power sequencing. GND must be applied first; thereafter, VCC(A) and VCC(B) may ramp at different rates. If either supply drops to GND, Suspend mode engages automatically, placing both ports in high-impedance state without requiring external control.
Does the DIR pin require a pull-up or pull-down resistor during power-up?
No external bias is required. The DIR input has CMOS-compatible thresholds referenced to VCC(A), and its state is only sampled after VCC(A) stabilizes. During power-up, the internal state is undefined until VCC(A) reaches valid logic threshold; however, IOFF ensures outputs remain safely disabled until both supplies are active.
How does the 74AVC2T45GN,115 handle bus contention in bidirectional mode?
It does not prevent contention autonomously. System design must ensure DIR is de-asserted (and ports placed in high-Z) before changing direction. Table 17 in the datasheet defines a four-state handshake sequence using external pull-ups/downs and controlled DIR toggling to avoid simultaneous drive on shared lines.
