Product details
Overview
74LVC2T45GS-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 74LVC2T45GS-Q100 datasheet, 74LVC2T45GS-Q100 pinout, 74LVC2T45GS-Q100 application, or 74LVC2T45GS-Q100 equivalent, key selection criteria include bidirectional voltage translation capability, AEC-Q100 Grade 1 qualification, IOFF leakage performance (<±2 μA), suspend-mode behavior during supply loss, and timing compatibility with high-speed serial buses operating up to 420 Mbps.
Technical Context
This device implements a dual-port, direction-controlled bus transceiver architecture where DIR selects signal flow: HIGH enables A→B translation, LOW enables B→A. Each port is referenced to its own supply rail (VCC(A) for pins 1A, 2A, DIR; VCC(B) for 1B, 2B), allowing independent logic-level domains. The IOFF circuit disables outputs when either VCC is at GND, preventing backflow current during partial power-down.
It supports JEDEC-compliant voltage standards (JESD8-7, JESD8-5, JESD8C, JESD36) and includes active bus-hold circuitry on all I/Os in the LVCH variant-though the 74LVC2T45GS-Q100 (non-H) lacks bus hold per Table 8 footnote [4]. Propagation delays are supply- and temperature-dependent, with worst-case tPLH/tPHL ≤23.5 ns over −40 °C to +125 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Range | VCC(A): 1.2 V–5.5 V; VCC(B): 1.2 V–5.5 V - enables translation between any two low-voltage nodes (e.g., 1.8 V MCU ↔ 3.3 V sensor) |
| Operating Temp | −40 °C to +125 °C - qualified per AEC-Q100 Grade 1 for under-hood and cockpit automotive applications |
| Max Data Rate | 420 Mbps (3.3 V ↔ 5.0 V) - supports high-speed inter-IC communication without external clocking |
| IOFF Leakage | ±2 μA max at −40 °C to +125 °C - ensures safe partial power-down when one supply is off |
| Output Drive | ±24 mA at VCC = 3.0 V - drives standard CMOS loads with margin across voltage ranges |
| Propagation Delay | tPLH/tPHL ≤23.5 ns (worst-case, −40 °C to +125 °C) - meets timing budgets for 20+ MHz parallel bus interfaces |
| ICC Supply Current | 16 μA max (A+B ports, VCC = 1.2–5.5 V) - ultra-low static power for always-on automotive subsystems |
Pinout & Package
XSON8 package (SOT1203), 1.35 × 1.0 × 0.35 mm, no leads, 8-terminal surface-mount. Body marking "V5", pin 1 indicator at lower-left corner below marking.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | VCC(A) | Supply for port A (1A, 2A) and DIR input - defines logic thresholds for A-side signals and direction control |
| 2 | 1B | Data I/O terminal for port B - bidirectionally translates logic levels relative to VCC(B) |
| 3 | 2B | Data I/O terminal for port B - pairs with 1B for dual-bit translation (e.g., I²C SDA/SCL, UART TX/RX) |
| 4 | VCC(B) | Supply for port B (1B, 2B) - independent of VCC(A), enabling true dual-domain operation |
| 5 | DIR | Direction control input referenced to VCC(A) - HIGH = A→B, LOW = B→A; controls internal transceiver path |
| 6 | 2A | Data I/O terminal for port A - referenced to VCC(A); paired with 1A for full dual-bit interface |
| 7 | 1A | Data I/O terminal for port A - primary A-side I/O; used with 2A for parallel data lanes |
| 8 | GND | Common ground reference - required for noise immunity and proper IOFF/suspend functionality |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent supply rails | VCC(A) and VCC(B) each support 1.2–5.5 V - eliminates need for external level shifters in mixed-voltage systems |
| IOFF partial power-down | Outputs disable automatically if either VCC drops to GND - prevents back-current damage during supply sequencing |
| Suspend mode | Both ports enter high-impedance state when VCC(A) = GND or VCC(B) = GND - essential for hot-plug and sleep-mode safety |
| AEC-Q100 Grade 1 qualification | Tested to −40 °C to +125 °C ambient - certified for engine bay, transmission, and ADAS ECU deployment |
| High noise immunity | Meets JEDEC standards JESD8-7/5/8C/36 - ensures robust operation in electrically noisy automotive environments |
Applications
| Automotive Infotainment Interface | ADAS Camera Sensor Link |
|---|---|
|

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 |
|---|---|---|---|
| 74LVCH2T45GS-Q100 | Includes active bus-hold circuitry on all I/Os; otherwise identical pinout, specs, and qualification | Eliminates need for external pull-ups on floating inputs in un-driven states - reduces BOM count in sparse-bus designs | Select when unused I/Os may float during system sleep; adds ~100 μA ICC at VCC = 3.3 V vs. LVC version |
| SN74AVC2T245RSWR | Texas Instruments part; same dual-supply, 2-bit, 3-state function; AEC-Q100 Grade 2 (−40 °C to +105 °C), not Grade 1 | Limited to cabin-only applications; lacks full under-hood thermal rating and IOFF leakage spec at +125 °C | Acceptable for non-safety-critical infotainment modules where extended temperature range is not required |
Compared with 74LVCH2T45GS-Q100, the bus-hold variant adds input stability at cost of higher static current; compared with SN74AVC2T245RSWR, the Nexperia part delivers full AEC-Q100 Grade 1 compliance and tighter IOFF leakage control for demanding power-gated automotive subsystems.

FAQ
What is the maximum allowable voltage difference between VCC(A) and VCC(B)?
The datasheet specifies no explicit ΔVCC limit; both supplies operate independently from 1.2 V to 5.5 V. Absolute maximum ratings allow VCC(A) and VCC(B) to differ by up to 5.0 V (e.g., VCC(A) = 1.2 V, VCC(B) = 5.0 V), provided each stays within its −0.5 V to +6.5 V absolute limit and IO current limits are observed.
Does 74LVC2T45GS-Q100 support hot insertion?
Yes - the IOFF circuitry ensures outputs go high-impedance when either VCC is at GND, preventing damaging back-current during live insertion. This, combined with ±4000 V HBM ESD rating, makes it suitable for hot-plug automotive submodules such as removable camera assemblies or diagnostic dongles.
Can DIR be driven from a different voltage domain than VCC(A)?
No - DIR is referenced strictly to VCC(A). Its VIH/VIL thresholds scale with VCC(A) (e.g., VIH = 0.65×VCC(A) for 1.4–1.95 V range). Driving DIR from a separate rail risks invalid logic levels and undefined direction control; it must be sourced from the same domain as port A.
How does suspend mode behave when only VCC(A) is powered?
When VCC(A) = VDD and VCC(B) = GND, the device enters suspend mode: both 1A/2A and 1B/2B ports go high-impedance, regardless of DIR state. This isolates the B-side circuitry completely, protecting downstream 3.3 V or 5.0 V components from undriven or floating conditions.
