Product details

Overview

74LVCH16245ADGV-QJ from Nexperia is a 16-bit automotive-grade bus transceiver with dual 8-bit directional control, 3-state outputs, 5.5 V overvoltage-tolerant inputs, and bus-hold functionality on all data I/Os. It operates from 1.2 V to 3.6 V, supports mixed-voltage translation between 3.3 V and 5 V systems, and features IOFF partial power-down protection. It is qualified to AEC-Q100 Grade 1 (−40 °C to +125 °C) for use in engine control units and ADAS domain controllers.

For engineers reviewing the 74LVCH16245ADGV-QJ datasheet, 74LVCH16245ADGV-QJ pinout, 74LVCH16245ADGV-QJ application, or 74LVCH16245ADGV-QJ equivalent, this device is selected for high-noise automotive data buses requiring robust level-shifting, bus stability without external pull-ups, and guaranteed 3-state isolation during power sequencing.

Technical Context

The device implements two independent 8-bit bidirectional data paths, each controlled by dedicated DIR and OE pins (1DIR/1OE and 2DIR/2OE), enabling flexible partitioning as either one 16-bit or two 8-bit transceivers. Schmitt-trigger inputs ensure noise immunity against slow-rising signals common in automotive harnesses.

Its IOFF circuit actively disables outputs when VCC = 0 V, blocking backflow current during hot-insertion or partial power-down-critical for ASIL-B compliant subsystems. Bus-hold circuitry maintains valid logic states on un-driven data lines, eliminating need for external termination resistors in CAN/LIN gateway interfaces.

Key Specifications

Ambient Temperature Range	−40 °C to +125 °C - Qualified for under-hood and transmission-control applications per AEC-Q100 Grade 1.

Pinout & Package

74LVCH16245ADGV-QJ uses the SOT480-1 package: TVSOP48, 48-pin, 0.4 mm lead pitch, 4.4 mm body width, with exposed thermal pad not connected internally.

Pin/Terminal	Circuit Role	Design Meaning
1DIR, 2DIR (Pins 1, 24)	Direction control input	Determines data flow direction per 8-bit bank: HIGH = A→B, LOW = B→A.
1OE, 2OE (Pins 48, 25)	Output enable (active LOW)	Asserting LOW enables corresponding 8-bit outputs; HIGH forces high-impedance state.
1A0–1A7, 2A0–2A7 (Pins 37–47, 26–36)	Data I/O port A	First and second 8-bit bidirectional data bus segment; includes bus-hold on all pins.
1B0–1B7, 2B0–2B7 (Pins 2–12, 13–23)	Data I/O port B	Complementary 8-bit bidirectional data bus segment; also bus-hold enabled.
V_CC (Pins 7, 18, 31, 42)	Power supply	Four distributed supply pins minimize IR drop and improve noise immunity across wide bus.
GND (Pins 4, 10, 15, 21, 28, 34, 39, 45)	Ground reference	Eight ground connections reduce ground bounce and support clean signal return paths.

Key Features

Feature	Design Value
Automotive qualification	AEC-Q100 Grade 1 certified - Validated for continuous operation at 125 °C ambient in safety-critical ECUs.
Bus-hold on all data I/Os	Eliminates need for external pull-up/down resistors - reduces BOM count and PCB area in modular gateway designs.
IOFF partial power-down	Prevents back-current when V_CC = 0 V - essential for fail-safe behavior during battery disconnect or sleep-mode transitions.
Schmitt-trigger inputs	Input hysteresis ≥ 0.3 V - rejects noise and ensures reliable edge detection on long-wire automotive traces.
Low-inductance pin layout	Alternating V_CC/GND pins and symmetric I/O grouping - minimizes simultaneous switching noise in high-density ADAS modules.

Equivalent & Alternatives

The following parts are listed as comparable options for similar 16-bit bus transceiver applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
74LVC16245ADGV-QJ	No bus-hold circuit; lower drive strength (±24 mA vs ±32 mA); identical pinout and voltage specs.	Suitable where external pull-ups are acceptable and lower power consumption is prioritized over floating-line immunity.	Select when cost sensitivity outweighs need for bus-hold and system-level noise margin is assured.
SN74LVC16245ADGGR	Industrial temp range only (−40 °C to +85 °C); no AEC-Q100 qualification; same electrical specs otherwise.	Limited to non-safety-critical cabin electronics or prototyping; not approved for powertrain or chassis systems.	Choose only for non-automotive development or Tier-3 infotainment subsystems lacking functional safety requirements.

Compared with 74LVC16245ADGV-QJ and SN74LVC16245ADGGR, the 74LVCH16245ADGV-QJ uniquely combines AEC-Q100 Grade 1 qualification, integrated bus-hold, and IOFF - making it the sole option for production automotive data-path isolation where reliability, noise resilience, and power sequencing safety are mandatory.

FAQ

What is the function of the IOFF circuit in 74LVCH16245ADGV-QJ?

The IOFF circuit disables all outputs when V_CC drops to 0 V, preventing reverse current flow from live I/O lines into the unpowered device. This protects downstream circuitry during hot-swap events or partial power-down sequences in automotive modules, and is verified per AEC-Q100 stress testing protocols.

Does 74LVCH16245ADGV-QJ require external pull-up resistors on its data lines?

No. All data I/O pins (1A0–1A7, 1B0–1B7, 2A0–2A7, 2B0–2B7) integrate bus-hold circuitry that maintains the last-valid logic state without external biasing. This eliminates pull-up resistors in applications like LIN gateway buffers or diagnostic port interfaces where floating inputs could cause spurious interrupts.

Can 74LVCH16245ADGV-QJ interface between 1.8 V and 5 V logic domains?

Yes. Its inputs tolerate up to 5.5 V regardless of V_CC (1.2 V–3.6 V), and outputs swing rail-to-rail within V_CC. When V_CC = 1.8 V, it accepts 5 V inputs safely and drives 1.8 V-compatible loads - enabling direct translation from legacy 5 V sensors to modern low-voltage MCUs in body electronics.

How does the dual OE/DIR architecture improve system design flexibility?

The independent 1OE/1DIR and 2OE/2DIR controls allow partitioning the 16-bit bus into two synchronized but separately managed 8-bit channels. This supports asymmetric data flows - e.g., sending configuration commands on one channel while streaming sensor data on the other - without requiring additional glue logic or multiplexing.
