Product details
Overview
74AVC2T45GS,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 direction (A→B or B→A), and IOFF circuitry for partial power-down protection. Used in mixed-voltage SoC interfaces, such as connecting a 1.8 V FPGA I/O bank to a 3.3 V peripheral bus.
For engineers reviewing the 74AVC2T45GS,115 datasheet, 74AVC2T45GS,115 pinout, 74AVC2T45GS,115 application, or 74AVC2T45GS,115 equivalent, key selection criteria include bidirectional translation capability, IOFF-enabled suspend mode, 8-pin XSON package footprint, -40 °C to +125 °C operation, and JEDEC-compliant voltage thresholds across all supported supply combinations.
Technical Context
The device implements a dual-channel, direction-controlled transceiver architecture with separate supply references: pins 1A, 2A, and DIR are referenced to VCC(A); pins 1B and 2B to VCC(B). Direction control is unidirectional-DIR HIGH enables A→B transmission; DIR LOW enables B→A transmission-and no output enable (OE) pin is provided, requiring external bus contention management in bidirectional systems.
Suspend mode activates when either VCC(A) or VCC(B) is at GND, forcing both ports into high-impedance OFF-state. The IOFF circuit prevents damaging backflow current during partial power-down, and static input thresholds scale with respective VCC values per JEDEC standards JESD8-12 through JESD8-B.

| VCC(B) | Supply B reference | Powers and sets logic thresholds for 1B, 2B inputs/outputs |
Key Features
| Feature | Design Value |
|---|---|
| Dual-supply independence | VCC(A) and VCC(B) operate simultaneously at any combination from 0.8 V to 3.6 V, enabling direct interface between 1.2 V ASIC and 2.5 V sensor |
| IOFF partial power-down | Disables outputs and blocks backflow current when either supply is off, protecting powered subsystems during hot-swap or sleep transitions |
| Suspend mode | Automatically places both ports in high-Z when VCC(A) = 0 V or VCC(B) = 0 V-no external control required |
| JEDEC compliance | Fully conforms to JESD8-12 (0.8–1.3 V), JESD8-11 (0.9–1.65 V), JESD8-7 (1.2–1.95 V), JESD8-5 (1.8–2.7 V), and JESD8-B (2.7–3.6 V) |
| Low dynamic power | CPD = 2 pF (A→B path, 0.8–3.3 V), minimizing switching current in high-frequency I²C or SPI level-shifting 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 |
|---|---|---|---|
| TXS0102DCUR | Auto-direction sensing (no DIR pin); higher ICC (20 μA typ); supports 1.2–3.6 V only | Eliminates direction-control GPIO but adds bus contention risk in multi-master configurations | Select when system lacks dedicated DIR line and bus arbitration is handled externally |
| SN74AVC2T245RSWR | Same pinout (X2SON8), identical DIR control, but rated only to +85 °C and lacks JESD8-12 compliance below 1.1 V | Not qualified for extended-temperature automotive or industrial deployments requiring -40 °C to +125 °C | Select only for commercial-grade applications with ambient ≤85 °C and VCC ≥1.1 V |
Compared with TXS0102DCUR and SN74AVC2T245RSWR, the 74AVC2T45GS,115 uniquely delivers full 0.8–3.6 V dual-supply support, guaranteed -40 °C to +125 °C operation, and JEDEC-compliant thresholds down to 0.8 V-making it the only option qualified for ultra-low-voltage, extended-temperature, and safety-critical mixed-domain interfaces.

FAQ
Can 74AVC2T45GS,115 translate between 0.8 V and 3.3 V simultaneously?
Yes. VCC(A) can be set to 0.8 V while VCC(B) is set to 3.3 V, enabling bidirectional translation between those domains. Input thresholds scale with respective VCC values (e.g., VIH on port A = 0.65 × 0.8 V = 0.52 V), and output drive meets VOH/VOL specs under load at both rails. Maximum data rate in this configuration is 320 Mbit/s.
Does the device require a specific power-up sequence?
No. The 74AVC2T45GS,115 requires only that GND be applied first; VCC(A) and VCC(B) may be powered in any order or simultaneously. Internal circuitry ensures glitch-free operation and avoids undefined states during ramp-up, eliminating need for external sequencing components or firmware delays.
What happens when DIR is floating?
DIR is referenced to VCC(A) and has no internal pull-up/down. A floating DIR results in undefined direction control-potentially causing bus contention or metastability. Designers must tie DIR to a defined logic level (VCC(A) or GND) via MCU GPIO or passive resistor. The datasheet specifies VIH ≥ 0.65×VCC(A) and VIL ≤ 0.3×VCC(A) for reliable switching.
Is the XSON8 (SOT1203) package thermally enhanced?
No. The SOT1203 package for 74AVC2T45GS,115 is a standard XSON8 with 1.35 mm × 1.0 mm body and 0.35 mm height-no exposed thermal pad or copper slug. Its Ptot rating is 250 mW at +125 °C with 3.6 mW/K derating above +81 °C. For higher power dissipation, consider the thermal-enhanced SOT1233-2 (GX variant) instead.
