Product details
Overview
74AVC8T245PW-Q100 from Nexperia is an automotive-qualified 8-bit dual-supply translating transceiver enabling bidirectional level translation between 0.8 V and 3.6 V domains. It features independent VCC(A) and VCC(B) supplies, DIR-controlled direction, OE-enabled 3-state outputs, and IOFF circuitry for partial power-down. Used in ADAS domain controllers to interface 1.2 V sensor interfaces with 3.3 V CAN/FlexRay communication subsystems.
For engineers reviewing the 74AVC8T245PW-Q100 datasheet, 74AVC8T245PW-Q100 pinout, 74AVC8T245PW-Q100 application, or 74AVC8T245PW-Q100 equivalent, key selection criteria include voltage translation range (0.8–3.6 V per rail), AEC-Q100 Grade 1 qualification (−40 °C to +125 °C), TSSOP24 package with side-wettable flanks, and IOFF-enabled bus isolation during suspend mode.
Technical Context
This transceiver implements a dual-rail CMOS architecture with separate input reference domains: An, DIR, and OE pins are referenced to VCC(A); Bn pins are referenced to VCC(B). Direction control is synchronous-DIR HIGH enables An→Bn data flow; DIR LOW enables Bn→An flow. Output enable (OE) is active-low and asserts high-impedance on both ports when asserted.
Suspend mode activates when either VCC(A) or VCC(B) = GND, forcing all An and Bn terminals into high-impedance OFF-state regardless of DIR/OE state. The IOFF circuit prevents backflow current during asymmetric power-down, meeting JEDEC JESD78 Class II latch-up immunity (>100 mA).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Range | VCC(A): 0.8 V–3.6 V; VCC(B): 0.8 V–3.6 V - supports translation across 0.8/1.2/1.5/1.8/2.5/3.3 V logic nodes |
| Operating Temp | −40 °C to +125 °C - qualified per AEC-Q100 Grade 1 for under-hood automotive use |
| Max Data Rate | 380 Mbit/s - achievable for ≥1.8 V ↔ 3.3 V translation, enabling high-speed sensor-to-ECU links |
| Propagation Delay | 2.7 ns (min) to 9.9 ns (max) - varies by supply pair and direction; An→Bn is faster at higher VCC(B) |
| IOFF Leakage | ±1 μA max (VCC = 0 V) - ensures safe bus isolation during partial power-down in domain gateways |
| ESD Protection | HBM >8 kV, CDM >1 kV - robust against assembly and in-vehicle ESD events |
| Package | TSSOP24 (SOT355-1), 4.4 mm body width - surface-mount compatible with AOI-capable reflow processes |
Pinout & Package
TSSOP24 plastic thin shrink small outline package (SOT355-1), 24-lead, 4.4 mm body width, with side-wettable flanks for automated optical inspection (AOI) of solder joints.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | VCC(A) | Supply for A-side I/O and control inputs (DIR, OE); defines logic thresholds for An, DIR, OE |
| 2 | DIR | Direction control: HIGH = An→Bn; LOW = Bn→An; referenced to VCC(A) |
| 3–10 | A1–A8 | 8-bit bidirectional data port A; referenced to VCC(A); support 0.8–3.6 V input tolerance |
| 11–13 | GND | Three dedicated ground connections - mandatory low-impedance return for noise-sensitive automotive operation |
| 14–21 | B1–B8 | 8-bit bidirectional data port B; referenced to VCC(B); tolerate up to 3.6 V regardless of VCC(B) |
| 22 | OE | Active-low output enable; forces both A and B ports to high-Z when HIGH; referenced to VCC(A) |
| 23–24 | VCC(B) | Supply for B-side I/O; defines logic thresholds for Bn; independent of VCC(A) for true dual-voltage operation |
Key Features
| Feature | Design Value |
|---|---|
| Dual-rail voltage translation | Independent 0.8–3.6 V supplies on each port enable interoperability across mixed-voltage automotive subsystems (e.g., 1.2 V camera ISP ↔ 3.3 V video encoder) |
| IOFF partial power-down | Prevents damaging backflow current when one supply is powered down - critical for domain controller sleep/wake transitions |
| AEC-Q100 Grade 1 qualification | Validated for −40 °C to +125 °C operation with full parametric specs - meets requirements for engine bay and ADAS ECU placement |
| Side-wettable flanks (SWF) | TSSOP24 package enables automated optical inspection of solder joint integrity - essential for zero-defect automotive manufacturing |
| High-speed timing | Sub-3 ns propagation delay (An→Bn @ 3.3 V ↔ 3.3 V) supports real-time sensor fusion in time-critical ADAS applications |
Applications
| ADAS Sensor Hub Interface | Automotive Domain Controller Bus Bridge |

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 |
|---|---|---|---|
| SN74AVC8T245RHLR | Industrial grade (−40 °C to +85 °C); same TSSOP24 footprint but no AEC-Q100 qualification; lacks side-wettable flanks | Not suitable for under-hood or safety-critical modules; acceptable for cabin infotainment or non-automotive industrial use | Select only if AEC-Q100 Grade 1 and AOI capability are not required; verify thermal derating for extended temperature operation |
| 74LVC8T245PW-Q100 | Narrower supply range (1.65 V–3.6 V per rail); lower max speed (240 Mbit/s); identical AEC-Q100 Grade 1 and TSSOP24 package | Cannot translate below 1.65 V - unsuitable for sub-1.2 V AI accelerators or next-gen ultra-low-power MCUs | Choose when interfacing only 1.8 V/2.5 V/3.3 V subsystems; offers lower static current but sacrifices low-voltage flexibility |
Compared with SN74AVC8T245RHLR and 74LVC8T245PW-Q100, the 74AVC8T245PW-Q100 uniquely combines 0.8 V minimum supply support, AEC-Q100 Grade 1 qualification, and side-wettable flanks - making it the only option for automotive applications requiring sub-1.2 V compatibility and zero-defect manufacturing traceability.

FAQ
What is the minimum valid supply voltage for reliable operation on either rail?
The 74AVC8T245PW-Q100 is fully specified down to 0.8 V on both VCC(A) and VCC(B), with guaranteed VIH/VIL thresholds, propagation delay, and IOFF behavior across the full −40 °C to +125 °C range. Operation below 0.8 V is not characterized and may result in undefined logic states or increased leakage.
Can the device translate between 0.8 V and 3.6 V simultaneously, and what is the resulting timing penalty?
Yes - the device supports 0.8 V ↔ 3.6 V translation. At VCC(A) = 0.8 V and VCC(B) = 3.6 V, typical An→Bn propagation delay is 6.0 ns (25 °C), while Bn→An is 11.8 ns due to drive strength asymmetry. Full min/max specs are provided in Table 12 for −40 °C to +125 °C.
How does the IOFF circuit behave when only VCC(A) is powered and VCC(B) = 0 V?
When VCC(B) = 0 V and VCC(A) = 0.8–3.6 V, the IOFF circuit disables all Bn outputs, limiting leakage to ±1 μA maximum. Inputs A1–A8 remain functional and tolerant up to 3.6 V, allowing the A-side to monitor B-bus status via pull-ups without backfeed risk.
Is the TSSOP24 package (SOT355-1) compatible with standard reflow profiles for lead-free assembly?
Yes - the SOT355-1 package is qualified for IPC/JEDEC J-STD-020D moisture sensitivity level 1 (MSL1) and supports peak reflow temperatures up to 260 °C. Side-wettable flanks are designed for compatibility with standard AOI systems using 5-micron resolution optics.
