Product details
Overview
74AVC8T245BQ-Q100 from Nexperia is an automotive-grade 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 data direction (An↔Bn), active-low OE for 3-state output control, and IOFF circuitry for partial power-down. Used in automotive infotainment domain controllers interfacing 1.2 V SoCs with 3.3 V sensor hubs.
For engineers reviewing the 74AVC8T245BQ-Q100 datasheet, 74AVC8T245BQ-Q100 pinout, 74AVC8T245BQ-Q100 application, or 74AVC8T245BQ-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), DHVQFN24 package with side-wettable flanks, and maximum data rates up to 380 Mbit/s.
Technical Context
This device implements a dual-rail CMOS transceiver architecture with separate input-reference domains: An, DIR, and OE are referenced to VCC(A); Bn pins are referenced to VCC(B). Direction control is synchronous and non-latched - DIR state directly determines signal flow path without internal storage.
Suspend mode activates when either VCC(A) or VCC(B) = GND, forcing all An and Bn terminals into high-impedance OFF-state. IOFF circuitry actively disables outputs during power-down, limiting backflow current to ±1 μA (typical) and meeting 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 - enables translation across 0.8/1.2/1.5/1.8/2.5/3.3 V logic nodes |
| Temperature Range | −40 °C to +125 °C - qualified per AEC-Q100 Grade 1 for under-hood automotive use |
| Max Data Rate | 380 Mbit/s - achievable when translating ≥1.8 V to 3.3 V, supporting high-speed serial bus bridging |
| Propagation Delay | 2.7 ns (min) to 9.9 ns (max) - varies by supply pair and temperature; e.g., 2.7 ns An→Bn at VCC(A)=3.3 V, VCC(B)=3.3 V, −40 °C to +125 °C |
| IOFF Leakage | ±1 μA (typ) - ensures safe isolation during partial power-down without damaging backflow current |

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 | Commercial grade (−40 °C to +85 °C), QFN24 package without side-wettable flanks, no AEC-Q100 qualification | Not suitable for automotive under-hood or safety-critical domains requiring Grade 1 temperature range | Select only for cost-sensitive industrial or consumer applications where automotive qualification is unnecessary |
| TXS0108EPRJR | Auto-direction sensing (no DIR pin), lower max speed (60 Mbit/s), higher propagation delay (up to 22 ns), supports 1.2–3.6 V only | Lacks explicit direction control - unsuitable for deterministic full-duplex protocols like parallel sensor interfaces | Prefer when direction is predictable and speed <60 Mbit/s; avoid for high-speed bidirectional buses requiring DIR synchronization |
Compared with SN74AVC8T245RHLR and TXS0108EPRJR, the 74AVC8T245BQ-Q100 uniquely combines AEC-Q100 Grade 1 qualification, 380 Mbit/s capability, and explicit DIR control - making it the only option for high-speed, safety-compliant automotive domain bridging.

FAQ
What is the minimum allowable voltage difference between VCC(A) and VCC(B)?
No minimum voltage difference is required: VCC(A) and VCC(B) may be equal (e.g., both 1.8 V) or differ by up to 2.8 V (e.g., 0.8 V and 3.6 V). The device operates correctly across all combinations within the 0.8 V–3.6 V range per rail, as verified in Tables 6–13 of the datasheet.
Does the 74AVC8T245BQ-Q100 support hot insertion?
Yes - IOFF circuitry ensures that when either VCC(A) or VCC(B) is at GND, all I/Os enter high-impedance OFF-state with leakage ≤±1 μA. This prevents bus contention and backfeed during live board insertion, satisfying hot-swap requirements in modular automotive ECUs.
Can OE and DIR be driven from different voltage domains?
No - DIR and OE inputs are referenced exclusively to VCC(A) and must be driven by signals compliant with VCC(A)'s logic thresholds (VIH/VIL defined in Table 7). Driving them from VCC(B) or another rail risks undefined behavior or damage due to input overvoltage.
How does suspend mode affect timing parameters?
In suspend mode (VCC(A) = GND or VCC(B) = GND), all propagation, enable, and disable times become undefined - the device is fully isolated. Timing specifications apply only during active operation with both supplies within 0.8 V–3.6 V and stable.
