Product details
Overview
74AVC4T245PW-Q100 from Nexperia is a 4-bit dual-supply translating transceiver enabling bidirectional level translation between independent voltage domains (VCC(A) and VCC(B)), supporting 0.8 V to 3.6 V on each rail. It operates as two configurable 2-bit transceivers or one 4-bit unit, with direction control (nDIR), output enable (nOE), and IOFF partial power-down for automotive bus isolation. Used in ADAS domain controllers for SPI/UART voltage bridging between 1.2 V sensor interfaces and 3.3 V MCU peripherals.
For engineers reviewing the 74AVC4T245PW-Q100 datasheet, 74AVC4T245PW-Q100 pinout, 74AVC4T245PW-Q100 application, or 74AVC4T245PW-Q100 equivalent, key selection criteria include asymmetric supply tolerance, suspend-mode high-impedance behavior during rail collapse, JEDEC-compliant translation across JESD8-12/11/7/5/B standards, and AEC-Q100 Grade 1 qualification for under-hood deployment.
Technical Context
This device implements dual-rail CMOS logic with separate input-reference domains: nAn, nDIR, and nOE inputs referenced to VCC(A); nBn inputs referenced to VCC(B). Its bidirectional data path uses pass-gate-based translation without internal level-shifting circuitry, relying on rail-to-rail input voltage acceptance up to 3.6 V and IOFF-enabled isolation when either supply drops to GND.
The functional table defines three operational states: (1) nOE = LOW + nDIR = LOW enables B→A transmission; (2) nOE = LOW + nDIR = HIGH enables A→B transmission; (3) nOE = HIGH forces all outputs into high-impedance regardless of nDIR state. Suspend mode activates automatically if VCC(A) = 0 V or VCC(B) = 0 V, placing both port sides in OFF-state.
Key Specifications

Pinout & Package
TSSOP16 package (SOT403-1), 16-pin plastic thin shrink small outline, 4.4 mm body width, lead pitch 0.65 mm, exposed pad not electrically connected.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | VCC(A) | Supply rail for A-side I/O and control inputs (nAn, nDIR, nOE); sets input threshold references |
| 2, 3 | 1DIR, 2DIR | Independent direction controls per 2-bit segment; HIGH enables A→B, LOW enables B→A |
| 4–7 | 1A1, 1A2, 2A1, 2A2 | A-side bidirectional data terminals referenced to VCC(A); tolerate up to 3.6 V input |
| 8, 9 | GND | Dual ground pins - both must be connected to PCB ground plane for thermal and noise integrity |
| 10–13 | 2B2, 2B1, 1B2, 1B1 | B-side bidirectional data terminals referenced to VCC(B); tolerate up to 3.6 V input |
| 14, 15 | 2OE, 1OE | Active-LOW output enables per 2-bit segment; HIGH forces associated ports into high-Z |
| 16 | VCC(B) | Supply rail for B-side I/O; independent of VCC(A), enabling true dual-voltage domain operation |
Key Features
| Feature | Design Value |
|---|---|
| Configurable 2×2 or 1×4 topology | Two independent DIR/OE pairs allow flexible partitioning - e.g., isolate CAN FD PHY (1.8 V) from microcontroller (3.3 V) while sharing one transceiver |
| IOFF partial power-down | Automatically disables outputs and limits leakage to ±5 μA when either VCC rail collapses - critical for fail-safe shutdown in ADAS ECUs |
| Suspend mode | Enters high-Z on both sides when VCC(A) = 0 V or VCC(B) = 0 V - eliminates bus contention during cold-cranking or battery disconnect |
| JEDEC compliance | Validated across 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), JESD8-B (2.7–3.6 V) |
| Side-wettable flanks | TSSOP16 package (SOT403-1) supports AOI inspection of solder joints - improves manufacturing yield in automotive PCB assembly |

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74AVC4T245QPWRQ1 | TI part with identical pinout and AEC-Q100 Grade 1 rating; wider VCC range (0.8 V–3.6 V), but max data rate limited to 320 Mbit/s at 1.8 V ↔ 3.3 V | Lower max speed may constrain use in high-resolution display serial links | Select when TI ecosystem alignment or existing design reuse outweighs 60 Mbit/s speed advantage |
| 74LVC4T245PW-Q100 | Nexperia LVC variant; same TSSOP16 package but narrower VCC range (1.65 V–3.6 V); lacks JESD8-12/11 support below 1.65 V | Cannot translate 0.8 V or 1.2 V logic; unsuitable for ultra-low-voltage sensor interfaces | Choose only for cost-sensitive non-sensor applications where 1.65 V minimum supply is guaranteed |

FAQ
What is the maximum allowable voltage difference between VCC(A) and VCC(B)?
No maximum differential is specified - the device supports any combination within 0.8 V to 3.6 V per rail, including VCC(A) = 0.8 V and VCC(B) = 3.3 V simultaneously. Absolute maximum ratings limit each supply to −0.5 V to +4.6 V relative to GND, but functional operation requires both rails to be within recommended 0.8 V–3.6 V range.
Does the 74AVC4T245PW-Q100 support hot insertion?
Yes - IOFF circuitry ensures outputs enter high-impedance state when either VCC rail is at 0 V, preventing backdrive current during live insertion. Input clamping current is rated to ±50 mA, and HBM ESD exceeds 8 kV, satisfying automotive hot-swap requirements per ISO 10605.
Can nDIR and nOE be tied together for simplified control?
No - nDIR and nOE serve orthogonal functions: nDIR selects direction (A→B or B→A), while nOE enables/disables outputs. Tying them violates functional independence and risks undefined states. The datasheet specifies separate control per 2-bit segment (1DIR/1OE and 2DIR/2OE), requiring independent routing for full flexibility.
How does suspend mode behave when only VCC(A) is powered?
When VCC(A) = 3.6 V and VCC(B) = 0 V, the device enters suspend mode: all nAn and nBn pins go high-impedance, nDIR/nOE inputs are disabled, and IOFF leakage is limited to ±5 μA. This isolates the powered A-side bus from the unpowered B-side network, preventing unintended current paths in fault conditions.
