Product details
Overview
74LVC2T45GS,115 from Nexperia is a dual-bit, dual-supply translating transceiver with 3-state outputs enabling bidirectional level translation between independent voltage domains (1.2 V to 5.5 V). It features two 2-bit I/O ports (A and B), a direction control input (DIR), IOFF partial power-down protection, and operates across –40 °C to +125 °C. Used in mixed-voltage FPGA-to-processor interconnects, it supports up to 420 Mbps (3.3 V ↔ 5.0 V) data rates.
For engineers reviewing the 74LVC2T45GS,115 datasheet, 74LVC2T45GS,115 pinout, 74LVC2T45GS,115 application, or 74LVC2T45GS,115 equivalent, this device is selected for low-latency, rail-to-rail bidirectional voltage translation in space-constrained industrial controllers, automotive body electronics, and portable IoT sensor hubs where supply isolation and suspend-mode leakage control are critical.
Technical Context
The 74LVC2T45GS,115 implements a dual-supply architecture where port A (pins 1A, 2A, DIR, VCC(A)) references VCC(A), and port B (pins 1B, 2B, VCC(B)) references VCC(B); GND is common. DIR logic state determines data flow direction: HIGH enables A→B, LOW enables B→A. Both ports enter high-impedance OFF-state when either VCC(A) or VCC(B) = 0 V (suspend mode).
IOFF circuitry actively disables outputs during power-down, limiting backflow current to ±2 μA at –40 °C to +125 °C. The GS variant uses the SOT1203 XSON8 package (1.35 × 1.0 × 0.35 mm), optimized for thermal performance and board area efficiency in high-density PCB layouts.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC(A) / VCC(B) Range | 1.2 V to 5.5 V each - enables translation between any two low-voltage rails (e.g., 1.8 V MCU ↔ 3.3 V sensor, 2.5 V FPGA ↔ 5.0 V display driver) |
| Max Data Rate | 420 Mbps (3.3 V ↔ 5.0 V) - supports high-speed serial peripheral interconnects without external level-shifting ICs |
| Propagation Delay | 0.7 ns to 23.6 ns (A↔B), dependent on VCC pair - ensures timing predictability in synchronous bus designs |
| IOFF Leakage | ±2 μA max at –40 °C to +125 °C - prevents damaging current flow when one domain is powered off in hot-swap systems |
| Supply Current (ICC) | 16 μA max (A+B ports) - enables ultra-low-power operation in battery-backed subsystems |
| ESD Protection | HBM >4000 V, CDM >1000 V - meets industrial IEC 61000-4-2 requirements without external TVS diodes |
| Operating Temperature | –40 °C to +125 °C - qualified for under-hood automotive and industrial motor drive control environments |
Pinout & Package
XSON8 package (SOT1203): extremely thin, no-lead, 1.35 × 1.0 × 0.35 mm body, 8-terminal surface-mount design with wettable flanks for automated optical inspection.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | VCC(A) | Supply for port A and DIR input - defines logic thresholds and drive strength for A-side signals |
| 2 | 1B | Data I/O terminal for B-port bit 1 - referenced to VCC(B); bidirectional under DIR control |
| 3 | 2B | Data I/O terminal for B-port bit 2 - shares VCC(B) reference and 3-state behavior with 1B |
| 4 | GND | Common ground reference - required for signal integrity and ESD path continuity |
| 5 | DIR | Direction control input - HIGH = A→B, LOW = B→A; referenced to VCC(A) |
| 6 | 2A | Data I/O terminal for A-port bit 2 - referenced to VCC(A); bidirectional under DIR control |
| 7 | 1A | Data I/O terminal for A-port bit 1 - shares VCC(A) reference and 3-state behavior with 2A |
| 8 | VCC(B) | Supply for port B - defines logic thresholds and drive strength for B-side signals |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent supply rails | VCC(A) and VCC(B) operate from 1.2 V to 5.5 V - eliminates need for external regulators in multi-rail SoC interfaces |
| IOFF partial power-down | Outputs disable automatically when either VCC = 0 V - prevents backfeeding in modular power architectures |
| Suspend mode | Both ports go high-Z if VCC(A) = 0 V or VCC(B) = 0 V - essential for safe hot-plug operation in field-replaceable modules |
| Low dynamic power | CPD = 2–18 pF depending on direction and VCC - reduces switching power in high-frequency data paths |
| High noise immunity | Meets JEDEC JESD8-7/8-5/8C/36 standards - ensures robust operation in electrically noisy industrial enclosures |
Applications
| Industrial PLC Backplane Interface | Automotive Body Control Module (BCM) |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-supply translating transceiver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC2T45DCTR | SSOP-8 package (3.0 × 3.0 mm), higher thermal resistance, 100 mA max ICC | Better suited for prototyping and manual rework; less optimal for high-density automated assembly | Select when board-level test access or hand-soldering is required; avoid for thermally constrained layouts |
| TXS0102DCUR | Auto-direction sensing, no DIR pin, lower drive (±8 mA), 1.65–3.6 V only | Eliminates direction control logic but lacks 1.2 V/5.0 V support and IOFF suspend mode | Choose only for simple 1.8 V ↔ 3.3 V I²C/SPI links where direction is predictable and full rail flexibility is unnecessary |
Compared with SN74LVC2T45DCTR and TXS0102DCUR, the 74LVC2T45GS,115 delivers the broadest voltage range (1.2–5.5 V), smallest footprint (XSON8), and guaranteed suspend-mode isolation - making it the sole choice for automotive and industrial designs requiring rail-agnostic, hot-swap-safe level translation.

FAQ
What is the maximum allowable voltage difference between VCC(A) and VCC(B)?
The datasheet specifies independent absolute maximum ratings: VCC(A) and VCC(B) each tolerate –0.5 V to +6.5 V relative to GND. No differential limit is defined - the device functions correctly with VCC(A) = 1.2 V and VCC(B) = 5.5 V simultaneously, provided both remain within their individual limits and GND is common.
Does the 74LVC2T45GS,115 support hot insertion when one supply is active and the other is off?
Yes. When either VCC(A) or VCC(B) = 0 V, the device enters suspend mode: both A and B ports enter high-impedance OFF-state, and IOFF circuitry limits leakage to ±2 μA. This prevents back-driving and latch-up during live insertion into partially powered systems.
Can DIR be driven from a different voltage domain than VCC(A)?
No. DIR is referenced exclusively to VCC(A); its VIH/VIL thresholds scale with VCC(A) (e.g., VIH = 0.65×VCC(A) for 1.4–1.95 V operation). Driving DIR from VCC(B) or another rail violates input specifications and may cause undefined logic states or increased power consumption.
Is bus-hold functionality present on the 74LVC2T45GS,115?
No. Bus-hold (IBHL/IBHH) is exclusive to the 74LVCH2T45 variant. The 74LVC2T45GS,115 lacks internal bus-hold circuitry; external pull-up/down resistors are required to prevent floating inputs on unused A/B port pins.
