Product details
Overview
74LVC2T45GT-Q100 from Nexperia is an automotive-grade dual-bit, dual-supply translating transceiver with 3-state outputs enabling bidirectional level translation between 1.2 V and 5.5 V domains. It features independent VCC(A) and VCC(B) supplies, DIR-controlled data direction (A↔B), IOFF-enabled partial power-down, and operates across −40 °C to +125 °C. Used in automotive infotainment and ADAS domain controllers for interfacing mixed-voltage peripherals like sensors and displays.
For engineers reviewing the 74LVC2T45GT-Q100 datasheet, 74LVC2T45GT-Q100 pinout, 74LVC2T45GT-Q100 application, or 74LVC2T45GT-Q100 equivalent, key selection criteria include dual-rail voltage flexibility (1.2–5.5 V per port), AEC-Q100 Grade 1 qualification, suspend-mode high-impedance behavior during power loss, and verified 420 Mbps max data rate for 3.3 V ↔ 5.0 V translation.
Technical Context
The device implements a bidirectional bus 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 synchronous-DIR HIGH enables A→B transmission, DIR LOW enables B→A-and both ports enter high-impedance OFF-state when either VCC(A) or VCC(B) = GND (suspend mode).
IOFF circuitry actively disables outputs during power-down to prevent backflow current, while bus-hold functionality (in 74LVCH2T45 variant) maintains valid logic levels on floating inputs. The 74LVC2T45GT-Q100 variant does not include bus hold but retains full IOFF, ESD robustness (HBM >4000 V), and JEDEC-compliant voltage translation across JESD8-7/8-5/8C/36 standards.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Range (VCC(A)/VCC(B)) | 1.2 V to 5.5 V each - enables translation between any common low-voltage rails (1.2 V, 1.5 V, 1.8 V, 2.5 V, 3.3 V, 5.0 V) |
| Max Data Rate | 420 Mbps (3.3 V ↔ 5.0 V) - supports high-speed inter-processor communication in automotive ECUs |
| Propagation Delay (A→B, VCC=3.3 V) | 5.3 ns tPLH / 5.2 ns tPHL - ensures timing-critical signal integrity in real-time control loops |
| IOFF Leakage Current | ±2 μA max at −40 °C to +125 °C - guarantees safe hot-insertion and partial power-down in multi-rail systems |
| ESD Protection | HBM >4000 V, CDM >1000 V - meets stringent automotive board-level reliability requirements |
| Ambient Temperature Range | −40 °C to +125 °C - qualified for under-hood and cockpit electronics per AEC-Q100 Grade 1 |
| Output Drive Strength | ±24 mA at VCC = 3.0 V - drives standard CMOS loads without external buffers in distributed sensor networks |
Pinout & Package
XSON8 package (SOT833-1): plastic extremely thin small outline, no leads, 8 terminals, body size 1 × 1.95 × 0.5 mm, thermal pad optional, moisture sensitivity level MSL3.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | VCC(A) | Supply for port A (1A, 2A) and DIR input - defines logic thresholds and output swing for A-side signals |
| 2 | 1B | Data I/O terminal referenced to VCC(B) - bidirectionally transfers data when DIR enables B→A path |
| 3 | VCC(B) | Supply for port B (1B, 2B) - independently sets B-side voltage domain and output compliance |
| 4 | DIR | Direction control input referenced to VCC(A) - HIGH = A→B, LOW = B→A; controls internal switch matrix state |
| 5 | 2A | Data I/O terminal referenced to VCC(A) - active during A→B or B→A transfer per DIR state |
| 6 | 1A | Data I/O terminal referenced to VCC(A) - primary A-side channel; shares 3-state control with 2A |
| 7 | VCC(A) | Second connection to VCC(A) - reduces supply impedance and improves noise immunity for port A |
| 8 | GND | Common reference ground - return path for all supply and I/O currents; must be low-inductance |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent supply rails | VCC(A) and VCC(B) each configurable 1.2–5.5 V - eliminates need for external level shifters in mixed-voltage SoC interfaces |
| IOFF partial power-down | Outputs disable safely when either VCC = 0 V - prevents back-current damage during rail sequencing or fault conditions |
| Suspend-mode high-impedance | Both ports go to Z-state if VCC(A) = GND or VCC(B) = GND - ensures clean isolation in battery-disconnect scenarios |
| AEC-Q100 Grade 1 qualification | Validated for −40 °C to +125 °C operation - certified for powertrain, chassis, and ADAS applications |
| JEDEC standard compliance | JESD8-7 (1.2–1.95 V), JESD8-5 (1.8–2.7 V), JESD8C (2.7–3.6 V), JESD36 (4.5–5.5 V) - guarantees interoperability across voltage families |

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 |
|---|---|---|---|
| 74LVCH2T45GT-Q100 | Includes active bus-hold circuitry on all I/Os; otherwise identical pinout, specs, and qualification. | Eliminates need for external pull-ups on unused data lines in low-pin-count modules. | Select when floating-input immunity is required without external components; adds ~100 nA static current per held input. |
| SN74AVC2T245RSE | Texas Instruments part; same 2-bit dual-supply function but rated only to +85 °C industrial grade, not AEC-Q100. | Lacks automotive qualification and suspend-mode behavior under single-rail loss. | Acceptable for non-safety-critical cabin modules where temperature range ≤+85 °C and full AEC-Q100 is not mandated. |
Compared with 74LVCH2T45GT-Q100, the bus-hold variant adds input stability at minor current cost; compared with SN74AVC2T245RSE, the Nexperia part delivers guaranteed automotive operation, IOFF safety, and broader temperature margin - critical for EPS and powertrain integration.

FAQ
What is the maximum allowable voltage difference between VCC(A) and VCC(B)?
VCC(A) and VCC(B) may differ by up to 4.3 V (e.g., 1.2 V and 5.5 V simultaneously), as confirmed by absolute maximum ratings: −0.5 V to +6.5 V per supply, referenced to GND. No internal clamping limits differential operation, and IOFF remains functional regardless of rail offset.
Can DIR be driven from a different voltage domain than VCC(A)?
No - DIR is strictly referenced to VCC(A), and 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) violates input voltage limits and risks latch-up or undefined direction control.
Does the 74LVC2T45GT-Q100 support hot-swap insertion?
Yes - IOFF circuitry ensures outputs remain disabled and leakage stays below ±2 μA when either supply is at 0 V, preventing back-current flow during live insertion. This satisfies automotive hot-swap requirements for modular ECU designs.
How does suspend mode affect timing parameters?
In suspend mode (VCC(A) = 0 V or VCC(B) = 0 V), both ports enter high-impedance OFF-state within 15.5 ns (tPZL max at +125 °C), and propagation delays become undefined. The device draws <2 μA total ICC, making it suitable for ultra-low-power wake-on-event architectures.
