Product details
Overview
74AVC4TD245BQ-Q10X from Nexperia is a 4-bit dual-supply bidirectional voltage-level translating transceiver with independent A- and B-side supplies (VCC(A)/VCC(B) = 0.8 V to 3.6 V), four per-bit direction controls (DIR1–DIR4), active-low output enable (OE), and IOFF partial power-down protection. It enables translation between 0.8 V, 1.2 V, 1.5 V, 1.8 V, 2.5 V, and 3.3 V domains in automotive infotainment serial buses.
For engineers reviewing the 74AVC4TD245BQ-Q10X datasheet, 74AVC4TD245BQ-Q10X pinout, 74AVC4TD245BQ-Q10X application, or 74AVC4TD245BQ-Q10X equivalent, key selection criteria include configurable per-bit direction control, ±100 mA latch-up immunity, 380 Mbit/s max data rate (≥1.8 V ↔ 3.3 V), AEC-Q100 Grade 1 qualification, and suspend-mode high-impedance isolation when either supply is at GND.
Technical Context
This device implements eight independent 1-bit bidirectional I/O channels (A1–A4, B1–B4), each with dedicated DIRn control enabling asymmetric flow direction per channel. The A-side inputs (An, DIRn, OE) reference VCC(A); B-side I/Os reference VCC(B), allowing true dual-rail operation without level-shifter bias networks.
IOFF circuitry actively disables outputs during partial power-down, blocking backflow current when either VCC(A) or VCC(B) is at 0 V - critical for hot-swap and domain-isolation use cases. Suspend mode forces all An/Bn pins into high-impedance OFF-state regardless of DIRn/OE state when one supply is grounded.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Range | VCC(A) and VCC(B): 0.8 V to 3.6 V - supports translation across all common low-voltage logic families (0.8 V/1.2 V/1.5 V/1.8 V/2.5 V/3.3 V). |
| Max Data Rate | 380 Mbit/s (1.8 V ↔ 3.3 V) - enables high-speed inter-domain communication in ADAS sensor fusion links. |
| Propagation Delay | As low as 0.2 ns (A→B, VCC(A)=3.3 V, VCC(B)=3.3 V) - ensures timing-critical signal integrity in real-time control loops. |
| IOFF Leakage | ±5 μA max (VCC=0 V, VI/VO=0–3.6 V) - guarantees safe hot-plug operation without bus contention or damage. |
| ESD Protection | HBM >8 kV, CDM >1 kV - meets stringent automotive ESD robustness requirements per ISO 10605. |
| Operating Temp | −40 °C to +125 °C - qualified for under-hood and powertrain applications per AEC-Q100 Grade 1. |
| Latch-up Immunity | >100 mA per JESD78 Class II - prevents destructive latch-up during transient overvoltage events. |
Pinout & Package
DHVQFN16 (SOT763-1) package: 2.5 mm × 3.5 mm × 0.85 mm body, thermal-enhanced quad flat no-lead with exposed die pad (non-soldered or floating GND).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 8 | GND | Signal ground reference; Pin 1 index area marks orientation; thermal pad not electrically required. |
| 2, 7, 10, 15 | DIR1–DIR4 | Per-channel direction control: HIGH = An→Bn, LOW = Bn→An - enables mixed-direction data routing on same bus. |
| 3–6 | A1–A4 | Port A I/O pins referenced to VCC(A); support 0.8–3.6 V input tolerance up to 3.6 V. |
| 9 | OE | Active-low output enable: LOW enables transceiver, HIGH forces all A/B pins to high-Z - isolates buses during reset or sleep. |
| 11–14 | B1–B4 | Port B I/O pins referenced to VCC(B); tolerate inputs up to 3.6 V independent of VCC(B) level. |
| 16 | VCC(B) | Port B supply rail - sets B-side logic thresholds and output drive strength. |
| VCC(A) | Port A supply rail | Sets A-side logic thresholds, input reference, and DIRn/OE switching levels. |
Key Features
| Feature | Design Value |
|---|---|
| Configurable per-bit direction control | Four independent DIR inputs allow simultaneous A→B and B→A transfers on different bit lanes - eliminates need for external multiplexing logic. |
| IOFF partial power-down | Automatically disables outputs and blocks backflow current when either VCC(A) or VCC(B) is at 0 V - essential for domain power sequencing in automotive ECUs. |
| Suspend-mode isolation | When VCC(A) = 0 V or VCC(B) = 0 V, all An/Bn pins enter guaranteed high-Z state regardless of DIRn/OE - prevents bus leakage during deep sleep. |
| JEDEC-compliant voltage translation | Meets 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), and JESD8-B (2.7–3.6 V) - ensures interoperability across legacy and next-gen logic families. |
| High-speed propagation | tpd as low as 0.2 ns (A→B, 3.3 V ↔ 3.3 V) with <12 ns max delay across full temp/voltage range - supports >80 MHz clocked interfaces. |
Applications
| ADAS Camera Interface | Infotainment SoC Interconnect |
|---|---|

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 |
|---|---|---|---|
| SN74AVC4T245QPWRQ1 | TI part with identical 4-bit dual-supply architecture, but only two shared DIR pins (DIRA/DIRB) instead of four independent DIRn inputs. | Lacks per-bit direction control - requires external logic to route mixed-direction traffic on same bus. | Select when system uses uniform direction per port rather than per-bit flexibility; lower cost where granularity is unnecessary. |
| 74LVC4T245BQ-Q10X | Nexperia LVC variant with narrower supply range (1.2 V–3.6 V), no 0.8 V support, and no IOFF circuitry - lacks partial power-down capability. | Not suitable for ultra-low-voltage domains or hot-swap scenarios requiring backflow prevention. | Select only for 1.2 V+ systems where IOFF and 0.8 V operation are not required; lower static power at 1.2 V. |
Compared with SN74AVC4T245QPWRQ1 and 74LVC4T245BQ-Q10X, the 74AVC4TD245BQ-Q10X uniquely delivers per-bit direction control and IOFF-enabled partial power-down - critical for automotive domain-isolation architectures where mixed-voltage, mixed-direction, and fail-safe power sequencing are mandatory.

FAQ
What is the minimum valid supply voltage for reliable operation on both VCC(A) and VCC(B)?
The 74AVC4TD245BQ-Q10X is fully specified down to 0.8 V on both VCC(A) and VCC(B), with guaranteed functionality including IOFF, suspend mode, and 150 Mbit/s data rate (1.1 V ↔ 1.2 V). Below 0.8 V, parameters are not characterized and operation is not assured.
How does the IOFF feature behave when only VCC(A) is powered and VCC(B) is at 0 V?
When VCC(B) = 0 V and VCC(A) is powered, IOFF activates automatically: all B1–B4 outputs are disabled, and backflow current from A-side signals into the unpowered B-rail is blocked to ≤±5 μA - preventing damage to downstream 0 V-referenced circuits.
Can DIR1–DIR4 be tied together, or must they be driven independently?
DIR1–DIR4 may be tied together for uniform direction control across all four bits, but the device is designed to support independent control. Tying them simplifies routing but forfeits per-bit flexibility - e.g., A1→B1 and B2→A2 simultaneously - which is enabled only when DIRn pins are driven separately.
Is the exposed thermal pad on the DHVQFN16 package required to be soldered to PCB ground?
No. The exposed pad (terminal 1 index area) has no electrical or mechanical requirement to be soldered. If soldered, it must remain electrically floating or connected to GND - it is not internally bonded to any signal or power net and serves only thermal enhancement.
