Product details
Overview
74AVC16T245DGV-Q1J from Nexperia is a 16-bit dual-supply translating transceiver with bidirectional level-shifting, 3-state outputs, and AEC-Q100 Grade 1 automotive qualification. It supports independent VCC(A) and VCC(B) supplies from 0.8 V to 3.6 V, enabling voltage translation between 0.8 V, 1.2 V, 1.5 V, 1.8 V, 2.5 V, and 3.3 V domains. With two independent 8-bit directional control pairs (nDIR/nOE), it operates as either two 8-bit or one 16-bit transceiver in automotive infotainment data buses.
For engineers reviewing the 74AVC16T245DGV-Q1J datasheet, 74AVC16T245DGV-Q1J pinout, 74AVC16T245DGV-Q1J application, or 74AVC16T245DGV-Q1J equivalent, key selection criteria include dual-rail voltage translation range, IOFF-enabled partial power-down, suspend-mode behavior under single-rail shutdown, propagation delay asymmetry (nAn→nBn vs. nBn→nAn), and automotive-grade ESD robustness (HBM >8 kV).
Technical Context
This device implements two independent 8-bit bidirectional data paths, each with dedicated direction (nDIR) and output-enable (nOE) inputs referenced to VCC(A). Input and output circuits are isolated per supply domain: nAn/nDIR/nOE tied to VCC(A); nBn tied to VCC(B). The IOFF circuit actively disables outputs during power-down, blocking backflow current when either VCC(A) or VCC(B) = 0 V.
Suspend mode activates automatically when at least one supply is at GND, forcing all I/O ports into high-impedance OFF-state regardless of nOE/nDIR states. Translation direction is static per port pair: HIGH on nDIR enables nAn → nBn flow; LOW enables reverse flow. Output drive strength scales with supply voltage - e.g., VOL ≤ 0.07 V at IO = 1.5 mA and VCC = 0.8 V.
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 interoperability across six standard logic voltages without external level shifters. |
| Max Data Rate | 380 Mbit/s (≥1.8 V ↔ 3.3 V) - supports high-speed parallel bus bridging in ADAS sensor fusion modules. |
| Propagation Delay | nAn→nBn: 2.7 ns min / 9.2 ns max (-40°C to +85°C); nBn→nAn: 2.7 ns min / 8.0 ns max - asymmetric timing requires direction-aware PCB layout and timing closure. |
| IOFF Leakage | ±5 μA max (VCC = 0 V, VI/VO = 0–3.6 V) - ensures safe hot-swap and rail sequencing in multi-voltage automotive ECUs. |
| ESD Protection | HBM >8000 V, CDM >1000 V - meets stringent automotive board-level ESD immunity requirements per ISO 10605. |
| Operating Temp | -40°C to +125°C - qualified for engine bay and powertrain control unit deployment per AEC-Q100 Grade 1. |
Pinout & Package
Package: TVSOP48 (SOT480-1), plastic thin shrink small outline, 48 leads, 0.4 mm pitch, 4.4 mm body width, 1.1 mm max height.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1DIR, 24DIR | Direction control (Port 1) | Active-HIGH selects nA1–nA8 → nB1–nB8; referenced to VCC(A); controls 8-bit path A. |
| 1OE, 25OE | Output enable (Port 1) | Active-LOW disables both nA1–nA8 and nB1–nB8 outputs; referenced to VCC(A); enables 3-state isolation. |
| 1A1–1A8, 2A1–2A8 | Data I/O (Side A) | 8-bit bidirectional port referenced to VCC(A); accepts inputs up to 3.6 V regardless of VCC(A) level. |
| 1B1–1B8, 2B1–2B8 | Data I/O (Side B) | 8-bit bidirectional port referenced to VCC(B); compatible with mixed-voltage memory or peripheral interfaces. |
| VCC(A), VCC(B) | Supply rails | VCC(A) powers nAn, nDIR, nOE logic; VCC(B) powers nBn logic; independent regulation required. |
| GND (Pins 4,10,15,21,28,34,39,45) | Ground reference | All eight GND pins must be connected to system ground to ensure signal integrity and thermal dissipation. |
Key Features
| Feature | Design Value |
|---|---|
| Dual-rail voltage translation | Supports 0.8 V ↔ 1.2 V, 1.2 V ↔ 1.8 V, 1.8 V ↔ 2.5 V, 2.5 V ↔ 3.3 V, and all combinations - eliminates discrete level-shifter ICs in multi-voltage SoC interconnects. |
| IOFF partial power-down | Blocks damaging backflow current when either VCC(A) or VCC(B) is unpowered - critical for safe firmware updates and sleep/wake transitions in telematics gateways. |
| Suspend mode | Automatic high-Z state when any supply = GND - prevents bus contention during rail sequencing or brownout conditions in battery management systems. |
| Asymmetric propagation delay | nAn→nBn delay is faster than nBn→nAn at same voltage pair (e.g., 5.9 ns vs. 11.8 ns at 1.8 V ↔ 3.3 V) - enables optimized timing budget allocation per data direction. |
| AEC-Q100 Grade 1 qualification | Validated for -40°C to +125°C operation with latch-up immunity >100 mA - meets functional safety requirements for ASIL-B automotive subsystems. |

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 |
|---|---|---|---|
| SN74AVC16T245QPWRQ1 | TI part; identical 16-bit dual-rail architecture but uses different IOFF implementation and slightly higher ICC (max 185 μA vs. 125 μA at 3.3 V). | Qualified to AEC-Q100 Grade 1 but lacks JESD8-12 compliance for sub-1.0 V operation. | Select when TI ecosystem alignment or existing design reuse outweighs sub-1.0 V compatibility needs. |
| 74LVC16T245PW-Q100 | Nexperia LVC variant; narrower VCC range (1.2 V–3.6 V), no 0.8 V support, lower ESD (HBM >2 kV), and no suspend mode. | Not suitable for ultra-low-voltage domains like 0.8 V AI accelerators or advanced node MCUs. | Choose only for cost-sensitive non-critical applications where 1.2 V minimum supply is guaranteed. |
Compared with SN74AVC16T245QPWRQ1 and 74LVC16T245PW-Q100, the 74AVC16T245DGV-Q1J uniquely supports 0.8 V operation, offers superior HBM ESD protection (>8 kV), and guarantees suspend-mode behavior - making it the only option for next-gen automotive electronics requiring full rail flexibility and robustness.

FAQ
What is the minimum valid VCC(A) and VCC(B) combination for functional operation?
The device operates with any combination where both VCC(A) and VCC(B) are ≥0.8 V and ≤3.6 V. Valid pairs include 0.8 V/1.2 V, 1.5 V/3.3 V, and 2.5 V/2.5 V. Operation below 0.8 V on either rail forces suspend mode - no data transfer occurs, but IOFF protection remains active.
How does suspend mode behave when only VCC(A) is powered?
When VCC(A) = 3.6 V and VCC(B) = 0 V (GND), all nA1–nA8 and nB1–nB8 pins enter high-impedance OFF-state regardless of nDIR/nOE logic levels. This prevents back-driving of the unpowered B-side bus and protects downstream 3.3 V peripherals from damage.
Can nDIR and nOE be driven from different voltage domains?
No - both nDIR and nOE inputs are referenced exclusively to VCC(A) and must be driven by signals compliant with VCC(A) logic thresholds (VIH ≥0.65×VCC(A), VIL ≤0.35×VCC(A)). Driving them from VCC(B) or another rail violates input specifications and risks malfunction.
Is the 74AVC16T245DGV-Q1J pin-compatible with non-automotive variants like 74AVC16T245DGV?
Yes - mechanical pinout and electrical functionality are identical between the Q1J (AEC-Q100 qualified) and standard DGV versions. However, only the Q1J variant is tested and certified for automotive temperature range (-40°C to +125°C) and stress conditions per AEC-Q100.
