Product details
Overview
74LVC1T45GM-Q100 from Nexperia is a single-bit, dual-supply translating transceiver with 3-state outputs enabling bidirectional voltage-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 automotive-grade AEC-Q100 Grade 1 qualification for use in body control modules and ADAS sensor interfaces.
For engineers reviewing the 74LVC1T45GM-Q100 datasheet, 74LVC1T45GM-Q100 pinout, 74LVC1T45GM-Q100 application, or 74LVC1T45GM-Q100 equivalent, key selection criteria include dual-rail supply flexibility (1.2–5.5 V per rail), suspend-mode high-impedance behavior during power loss, ±24 mA output drive at 3.0 V, 420 Mbps max data rate (3.3 V → 5.0 V), and IOFF leakage < ±2 μA at -40 °C to +125 °C.
Technical Context
This device implements a bidirectional bus transceiver architecture where DIR selects signal flow direction: HIGH enables A→B translation, LOW enables B→A. Both data ports (A, B) and DIR are referenced to their respective supply rails (VCC(A) and VCC(B)), allowing independent domain operation without level-shifting external circuitry.
IOFF circuitry actively disables outputs when either VCC(A) or VCC(B) drops to GND, preventing backflow current and enabling hot-swap capability. In suspend mode, both A and B ports enter high-impedance OFF-state regardless of DIR state - a critical feature for automotive power sequencing and fail-safe isolation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Range (VCC(A)/VCC(B)) | 1.2 V to 5.5 V each - supports translation across 1.2 V, 1.5 V, 1.8 V, 2.5 V, 3.3 V, and 5.0 V logic domains |
| Max Data Rate | 420 Mbps (3.3 V → 5.0 V) - enables high-speed inter-domain communication in automotive infotainment links |
| Output Drive | ±24 mA at VCC = 3.0 V - sufficient to drive 50 Ω transmission lines or multiple CMOS loads without buffering |
| IOFF Leakage | ±2 μA max at -40 °C to +125 °C - ensures safe partial power-down during ECU sleep modes |
| Propagation Delay (A→B) | 0.7 ns min / 48.6 ns max at 5.0 V → 5.0 V, -40 °C to +125 °C - meets timing budgets for CAN FD and LIN gateway arbitration |
| ESD Protection | HBM > 4000 V, CDM > 1000 V - exceeds automotive system-level ESD immunity requirements per ISO 10605 |
| Operating Temperature | -40 °C to +125 °C - qualified for under-hood and ADAS camera module environments |
Pinout & Package
XSON6 plastic extremely thin small outline package (SOT886); 6-terminal, no-lead surface-mount package; body dimensions 1.0 mm × 1.45 mm × 0.5 mm; thermal pad on underside for enhanced PCB heat dissipation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - VCC(A) | Supply for port A and DIR input | Reference rail for A-port I/O and direction control logic; must be stable before enabling data transfer |
| 2 - GND | Ground reference | Common return path for both supply domains; requires low-inductance connection to minimize noise coupling |
| 3 - A | Data I/O port A | Bidirectional data terminal referenced to VCC(A); accepts inputs up to 5.5 V regardless of VCC(A) level |
| 4 - B | Data I/O port B | Bidirectional data terminal referenced to VCC(B); supports hot-plug operation via IOFF when VCC(B) is unpowered |
| 5 - DIR | Direction control input | Logic-level input referenced to VCC(A); HIGH = A→B, LOW = B→A; controls output enable and data path |
| 6 - VCC(B) | Supply for port B | Independent rail for B-port I/O; allows asynchronous power-up/down relative to VCC(A) in modular ECUs |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 1 qualification | Validated for automotive use from -40 °C to +125 °C ambient, meeting stringent reliability and lifetime requirements |
| IOFF partial power-down | Prevents damaging backflow current when either VCC rail is powered off - essential for domain-isolated vehicle networks |
| Suspend mode | Automatic high-impedance state on both A and B ports when VCC(A) = GND or VCC(B) = GND - enables safe power sequencing |
| Wide voltage translation | Supports all common automotive logic levels (1.2 V to 5.5 V) on both sides without external components or configuration |
| Bus hold circuitry (74LVCH variant only) | Not applicable to 74LVC1T45GM-Q100 - this part lacks internal bus hold; external pull-ups required for floating inputs |

FAQ
Can 74LVC1T45GM-Q100 translate between 1.2 V and 5.0 V simultaneously?
Yes. VCC(A) can be set to 1.2 V while VCC(B) is set to 5.0 V, enabling bidirectional translation between those domains. The device guarantees correct logic thresholds and output drive strength across this full range, with maximum data rate of 75 Mbps in that configuration per datasheet Table 2.
What happens to the A and B ports when VCC(A) = 0 V and VCC(B) = 3.3 V?
Both A and B ports enter high-impedance OFF-state (suspend mode), regardless of DIR state or input voltage. This prevents back-current flow from the powered B-side into the unpowered A-side, satisfying automotive power-loss safety requirements.
Is external pull-up required on the DIR pin?
Yes. The DIR input has no internal bus hold or pull-up; it must be actively driven HIGH or LOW by the controlling MCU. Leaving DIR floating may cause undefined data direction and unintended bus contention - a design violation per datasheet Section 7 function table.
Does this part support hot-swap insertion while VCC(B) is powered?
Yes. IOFF circuitry ensures the B port remains safely disabled if VCC(A) is unpowered during insertion, preventing backfeed into the A-side. However, VCC(B) must be stable before asserting DIR or driving A - hot-swap capability applies only to the unpowered domain side.
