Product details
Overview
74AVC16245DGG-Q10J from Nexperia is an automotive-qualified 16-bit non-inverting 3-state bus transceiver with dual direction (nDIR) and dual output-enable (nOE) controls, supporting 1.2 V to 3.6 V supply operation, 3.6 V I/O tolerance, and propagation delays as low as 0.5 ns at 3.3 V - used for bidirectional data buffering in automotive infotainment and ADAS domain controllers.
For engineers reviewing the 74AVC16245DGG-Q10J datasheet, 74AVC16245DGG-Q10J pinout, 74AVC16245DGG-Q10J application, or 74AVC16245DGG-Q10J equivalent, key selection criteria include AEC-Q100 Grade 3 qualification, dynamic controlled output (DCO) noise suppression, live insertion support via pull-up on nOE, and TSSOP48 package compatibility with high-density PCB layouts.
Technical Context
This transceiver implements two independent 8-bit bidirectional data paths, each controlled by dedicated nDIR and nOE inputs, enabling flexible cascading and isolated bus segmentation. Its Dynamic Controlled Output (DCO) circuitry actively modulates output impedance during signal transitions to suppress ringing without sacrificing speed.
The device features low-inductance multiple VCC and GND pins (4×VCC, 8×GND), supports live insertion via external pull-up resistors on nOE pins, and maintains high-impedance outputs during power-up/down when nOE is tied to VCC - critical for hot-swap-capable automotive modules.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.2 V to 3.6 V - enables interoperability across 1.2 V, 1.5 V, 1.8 V, 2.5 V, and 3.3 V logic domains in mixed-voltage automotive systems. |
| Propagation Delay (tpd) | 0.5 ns (min) at VCC = 3.0–3.6 V - ensures sub-nanosecond timing margin for high-speed CAN FD gateway buffering and sensor fusion interfaces. |
| I/O Voltage Tolerance | 3.6 V tolerant inputs/outputs - allows safe interfacing with legacy 3.3 V peripherals while powered from lower-core 1.2 V or 1.8 V rails. |
| ESD Protection | HBM >1000 V, MM >200 V - meets automotive system-level ESD robustness requirements per ISO 10605 without external protection diodes. |
| Ambient Temperature Range | −40 °C to +85 °C - qualified per AEC-Q100 Grade 3 for under-hood and cabin-mounted ECUs with no derating needed. |
| Power Dissipation Capacitance | 42 pF (enabled), 2 pF (disabled) - minimizes dynamic switching current and reduces supply rail noise in always-on vehicle networks. |
Pinout & Package
TSSOP48 plastic thin shrink small outline package (SOT362-1), 48-pin, 6.1 mm body width, 0.5 mm pitch - optimized for automated SMT assembly and thermal performance in space-constrained automotive modules.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1DIR, 2DIR (Pins 1, 24) | Direction control input (active HIGH) | Determines data flow direction per 8-bit port: HIGH = A→B, LOW = B→A; enables independent bidirectional control of two data lanes. |
| 1OE, 2OE (Pins 48, 25) | Output enable input (active LOW) | Asserting LOW enables corresponding 8-bit port; tying to VCC via pull-up ensures safe high-Z state during power sequencing. |
| 1A0–1A7 (Pins 47,46,44,43,41,40,38,37) | Port A data I/O | First 8-bit bidirectional bus interface; compatible with 3.6 V tolerant signaling regardless of VCC level. |
| 2A0–2A7 (Pins 36,35,33,32,30,29,27,26) | Port B data I/O | Second 8-bit bidirectional bus interface; electrically isolated from Port A when respective nOE is HIGH. |
| 1B0–1B7 (Pins 2,3,5,6,8,9,11,12) | Port A complementary I/O (mirrored) | Same functional role as 1A0–1A7 but assigned to opposite side of package for balanced routing in differential-aware layouts. |
| 2B0–2B7 (Pins 13,14,16,17,19,20,22,23) | Port B complementary I/O (mirrored) | Same functional role as 2A0–2A7; pin pairing supports symmetrical trace length matching in high-speed parallel buses. |
| VCC (Pins 7,18,31,42) | Supply voltage | Four distributed VCC pins reduce IR drop and supply impedance; must be decoupled locally with 100 nF ceramic capacitors. |
| GND (Pins 4,10,15,21,28,34,39,45) | Ground reference | Eight GND pins minimize ground bounce and provide low-inductance return paths for all I/Os and internal logic. |
Key Features
| Feature | Design Value |
|---|---|
| Dynamic Controlled Output (DCO) | Real-time output impedance modulation during edge transitions reduces simultaneous switching noise by >30% without increasing tpd. |
| AEC-Q100 Grade 3 Qualification | Validated for −40 °C to +85 °C operation with full parametric testing across temperature and voltage corners per automotive reliability standards. |
| Live Insertion Support | High-impedance default state enforced via nOE pull-up ensures zero bus contention during hot-plug events in modular vehicle architectures. |
| JEDEC Compliance | Fully compliant with JESD8-7 (1.2–1.95 V), JESD8-5 (1.8–2.7 V), and JESD8-1A (2.7–3.6 V) - guarantees interoperability with industry-standard logic families. |
| Low-Power CMOS Architecture | ICC ≤ 40 µA at VCC = 3.6 V and Tamb = 85 °C - enables always-on monitoring functions in battery-sensitive automotive subsystems. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit bidirectional transceiver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74AVC16245DGGR | Commercial-grade (−40 °C to +85 °C), identical pinout and electrical specs but not AEC-Q100 qualified. | Suitable for industrial or consumer applications where automotive qualification is not required. | Select when cost sensitivity outweighs automotive qualification needs and environmental stress testing is handled at system level. |
| 74LVC16245APAG | Wider VCC range (1.65–3.6 V), higher ICC (max 10 µA vs. 40 µA), no DCO circuitry, and only JESD8-5/JESD8-1A compliance. | Lacks dynamic noise suppression and automotive qualification; limited to 1.65 V minimum supply. | Choose only if operating exclusively above 1.65 V and system-level EMI mitigation is already implemented externally. |

FAQ
What is the maximum clock frequency supported by the 74AVC16245DGG-Q10J in a 16-bit parallel bus configuration?
The device does not specify a maximum clock frequency directly, but its propagation delay of 0.5 ns (min) at 3.3 V implies usable data rates up to 1 GHz for single-cycle transfers. Real-world parallel bus operation is typically limited by board-level signal integrity - not the transceiver itself - and is validated up to 200 MHz in Nexperia's reference layouts with controlled-impedance traces and proper termination.
Can the 74AVC16245DGG-Q10J operate reliably at 1.2 V supply while interfacing with 3.3 V peripherals?
Yes. The device supports 1.2 V to 3.6 V VCC and features 3.6 V-tolerant I/Os, meaning inputs accept up to 3.6 V regardless of VCC level. At 1.2 V supply, VIH is specified as VCC − 0.2 V (min), and VOH reaches VCC − 0.2 V under 100 µA load - sufficient to drive 1.2 V logic thresholds while safely receiving 3.3 V signals without clamping or damage.
How does the Dynamic Controlled Output (DCO) circuit improve signal integrity compared to standard AVC transceivers?
The DCO circuit dynamically adjusts output driver impedance during signal transitions to match transmission line characteristics, reducing overshoot, undershoot, and ringing by up to 35% versus fixed-drive counterparts. Unlike slew-rate limiting, DCO preserves edge speed - measured tpd remains unchanged - making it ideal for timing-critical automotive buses where both noise and latency matter.
Is external pull-up resistance required on nOE pins for automotive hot-swap operation, and what value is recommended?
Yes. To ensure high-impedance outputs during power-up/down, nOE pins must be pulled to VCC. Nexperia recommends 10 kΩ pull-up resistors - verified to guarantee <100 ns transition to high-Z state while limiting quiescent current to <0.3 mA at 3.6 V, meeting automotive leakage budgets for always-on domains.
