Product details
Overview
74AVC4T245GU-Q100 from Nexperia is a 4-bit dual-supply translating transceiver enabling bidirectional level translation between 0.8 V and 3.6 V domains. It supports two independent 2-bit channels or unified 4-bit operation, features separate VCC(A) and VCC(B) supplies, direction control (nDIR), output enable (nOE), and IOFF partial power-down for automotive bus isolation. Used in ADAS domain controllers interfacing 1.2 V sensor interfaces with 3.3 V CAN FD gateway logic.
For engineers reviewing the 74AVC4T245GU-Q100 datasheet, 74AVC4T245GU-Q100 pinout, 74AVC4T245GU-Q100 application, or 74AVC4T245GU-Q100 equivalent, key selection criteria include voltage translation range (0.8–3.6 V per rail), AEC-Q100 Grade 1 qualification, suspend-mode behavior during rail loss, propagation delay asymmetry (e.g., 5.9 ns nAn→nBn at 1.8 V→2.5 V), and XQFN16 package thermal performance (250 mW Ptot).
Technical Context
This device implements dual-rail CMOS I/O architecture with independent input referencing: nAn/nDIR/nOE tied to VCC(A), nBn tied to VCC(B). Direction control is synchronous-HIGH on nDIR enables A→B data flow; LOW enables B→A. Output enable (nOE, active LOW) places both ports in high-impedance state, isolating buses.
IOFF circuitry activates when either VCC(A) or VCC(B) = GND, disabling outputs and limiting backflow current to ±1 μA (typical) to prevent damage during partial power-down. Suspend mode ensures nAn/nBn terminals enter high-impedance OFF-state regardless of input states, critical for automotive ECU hot-swap and sleep/wake transitions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Range | VCC(A): 0.8–3.6 V; VCC(B): 0.8–3.6 V - enables translation across all common low-voltage nodes (0.8/1.2/1.5/1.8/2.5/3.3 V) |
| Max Data Rate | 380 Mbit/s - achievable only for ≥1.8 V ↔ 3.3 V translation; lower rates apply for sub-1.8 V rails (e.g., 100 Mbit/s for 1.1 V ↔ 1.2 V) |
| Propagation Delay | nAn→nBn: 5.9 ns (VCC(A)=1.8 V, VCC(B)=2.5 V); nBn→nAn: 12.1 ns - asymmetric timing requires careful signal path budgeting |
| IOFF Leakage | ±1 μA (typ) - limits backflow current during power sequencing, satisfying ISO 16750-2 transient immunity requirements |
| ESD Rating | HBM >8 kV, CDM >1 kV - exceeds AEC-Q100 stress test thresholds for assembly and field reliability |
| Operating Temp | −40 °C to +125 °C - qualified for engine bay and ADAS front-end placement without derating |
| Power Dissipation | Ptot = 250 mW (XQFN16) - defines maximum continuous switching load before thermal shutdown in confined automotive enclosures |
Pinout & Package
XQFN16 package: 1.80 × 2.60 × 0.50 mm body, no leads, side-wettable flanks for AOI-compatible solder joint inspection, 16-terminal layout with exposed thermal pad (non-electrical, floating or GND).
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1OE | Active-LOW output enable for first 2-bit channel - asserts high-Z on 1A1/1A2/1B1/1B2 when HIGH |
| 2 | VCC(B) | Supply for B-side I/Os (1B1, 1B2, 2B1, 2B2) - sets logic threshold and drive strength for B-port signals |
| 3 | VCC(A) | Supply for A-side I/Os and controls (1A1, 1A2, 1DIR, 1OE) - reference for all A-port inputs and direction logic |
| 4 | 1DIR | Direction control for first 2-bit channel - HIGH enables 1A1/1A2 → 1B1/1B2; LOW enables reverse flow |
| 5 | 2DIR | Direction control for second 2-bit channel - independent of 1DIR, allowing mixed-direction operation per pair |
| 6 | 1A1 | Data terminal A1 - bidirectional I/O referenced to VCC(A); functions as input or output based on 1DIR state |
| 7 | 1A2 | Data terminal A2 - paired with 1A1 under shared 1DIR/1OE control; supports 2-bit parallel interface |
| 8 | 2A1 | Data terminal A1 of second channel - electrically isolated from first channel but shares VCC(A) supply |
| 9 | 2A2 | Data terminal A2 of second channel - enables independent 2-bit translation paths within single package |
| 10 | 2B2 | Data terminal B2 of second channel - referenced to VCC(B); output level follows VCC(B) even when VCC(A) differs |
| 11 | 2B1 | Data terminal B1 of second channel - maintains B-port logic levels independent of A-port supply voltage |
| 12 | 1B2 | Data terminal B2 of first channel - translates voltage while preserving signal integrity across rail boundaries |
| 13 | 1B1 | Data terminal B1 of first channel - supports hot-plug detection via IOFF when VCC(A) or VCC(B) collapses |
| 14 | 2OE | Active-LOW output enable for second 2-bit channel - isolates 2A1/2A2/2B1/2B2 independently from first channel |
| 15 | GND | Ground reference - both GND pins (10,11 in SOT1161) must be connected to PCB ground plane for noise immunity |
| 16 | 2B2 | Redundant pin assignment - per Fig. 6, pin 16 is 2B2; confirms dual-B-port routing in compact XQFN layout |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 1 qualification | Validated for −40 °C to +125 °C operation with lifetime reliability testing per automotive stress standards |
| Dual independent 2-bit channels | Enables concurrent translation of two separate buses (e.g., camera MIPI D-PHY AUX + radar SPI) without crosstalk |
| IOFF partial power-down | Prevents damaging back-current when one supply rail is powered off - essential for ECU sleep-mode compliance |
| Suspend mode on rail loss | Automatically forces all I/Os into high-Z when either VCC(A) or VCC(B) = GND - eliminates bus contention during power sequencing |
| XQFN16 with side-wettable flanks | Enables automated optical inspection of solder joints - improves manufacturing yield in automotive PCB assembly |

FAQ
What is the minimum operating voltage for reliable translation between 1.2 V and 3.3 V domains? The device supports VCC(A) and VCC(B) down to 0.8 V, so 1.2 V ↔ 3.3 V translation is fully specified with guaranteed timing (tpd ≤ 6.2 ns) and drive strength (VOH ≥ 2.3 V at 3.3 V) across −40 °C to +125 °C.
Can 74AVC4T245GU-Q100 translate between 0.8 V and 1.2 V while maintaining AEC-Q100 compliance?
Yes - the datasheet explicitly specifies operation at VCC(A) = 0.8 V and VCC(B) = 1.2 V with full AEC-Q100 Grade 1 qualification. Propagation delay is 6.5 ns (nAn→nBn) and 12.4 ns (nBn→nAn) at 25 °C, with worst-case values validated across temperature extremes.
How does the IOFF feature behave when only VCC(A) is powered?
When VCC(A) = 3.6 V and VCC(B) = 0 V (GND), IOFF activates automatically: A-port leakage is limited to ±1 μA (typ), and all nAn/nDIR/nOE pins enter high-impedance state. B-port pins (nBn) also go high-Z due to suspend mode, preventing backfeed into the unpowered rail.
Is the XQFN16 package compatible with standard reflow profiles for lead-free automotive PCB assembly?
Yes - the SOT1161-1 package is qualified for J-STD-020 moisture sensitivity level 1 (MSL1) and withstands peak reflow temperatures up to 260 °C. Its 0.50 mm height and side-wettable flanks ensure compatibility with automated optical inspection after standard Pb-free reflow.
