Product details

Overview

74LVC16245ADGV-Q1J from Nexperia is an automotive-qualified 16-bit bus transceiver with dual 8-bit directional control, 3-state outputs, 5.5 V overvoltage-tolerant inputs, and IOFF partial power-down protection. It operates from 1.2 V to 3.6 V supply, supports mixed-voltage translation between 3.3 V and 5 V systems, and features Schmitt-trigger inputs for noise immunity. It is used in automotive body control modules for bidirectional data bus isolation between microcontroller and peripheral subsystems.

For engineers reviewing the 74LVC16245ADGV-Q1J datasheet, 74LVC16245ADGV-Q1J pinout, 74LVC16245ADGV-Q1J application, or 74LVC16245ADGV-Q1J equivalent, this device delivers verified AEC-Q100 Grade 1 qualification, TVSOP48 package compatibility, dual OE/DIR control per byte lane, and bus hold functionality (in LVCH variant), enabling robust bidirectional level translation in safety-critical vehicle networks.

Technical Context

This transceiver implements two independent 8-bit bidirectional data paths, each controlled by dedicated OE (active-low) and DIR inputs. Its IOFF circuitry ensures high-impedance outputs during power-down, preventing backflow current when VCC = 0 V - critical for hot-swap and partial-power-down automotive architectures.

Schmitt-trigger inputs provide hysteresis (typically 0.3 V at VCC = 3.3 V), enabling reliable operation with slow-rising signals from mechanical sensors or legacy LIN interfaces. The device complies with JEDEC standards JESD8-7A, JESD8-5A, and JESD8-C/JESD36 across its full 1.2 V–3.6 V supply range.

Key Specifications

Parameter	Value and Actual Design Meaning
Supply Voltage Range	1.2 V to 3.6 V - enables direct interface with 1.8 V, 2.5 V, and 3.3 V logic domains without level shifters
Input Overvoltage Tolerance	Up to 5.5 V - allows safe connection to 5 V buses while powered from 3.3 V or lower supplies
Propagation Delay (t_pd)	1.0 ns (min) to 6.0 ns (max) at VCC = 3.3 V - supports >100 MHz bus toggle rates in automotive CAN/LIN gateway applications
IOFF Leakage Current	±10 μA max at VCC = 0 V - prevents damaging back-current during system power sequencing
Operating Temperature	−40 °C to +125 °C - qualified for engine bay and ADAS ECU environments per AEC-Q100 Grade 1
ESD Protection	HBM >2000 V, CDM >1000 V - meets automotive board-level ESD robustness requirements
Output Drive Strength	±24 mA at VCC = 3.0 V - sufficient to drive 30 pF loads across 15 cm PCB traces in distributed ECUs

Pinout & Package

74LVC16245ADGV-Q1J uses the SOT480-1 package: a 48-pin TVSOP with 0.4 mm lead pitch, 4.4 mm body width, and exposed thermal pad (not electrically connected). Pin numbering follows standard counter-clockwise layout with pin 1 index marker at top-left corner.

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; enables independent byte-lane routing
1OE, 2OE (Pins 25, 48)	Output enable (active LOW)	Asserting LOW enables corresponding 8-bit output bank; HIGH forces high-impedance state for bus sharing
1A0–1A7, 2A0–2A7 (Pins 26–47)	Data I/O port A	First and second 8-bit bidirectional data terminals; connect to microcontroller side of bus
1B0–1B7, 2B0–2B7 (Pins 2–23)	Data I/O port B	First and second 8-bit bidirectional data terminals; connect to peripheral or sensor-side bus
VCC (Pins 7, 18, 31, 42)	Power supply	Four dedicated supply pins minimize IR drop and ground bounce across high-speed switching
GND (Pins 4, 10, 15, 21, 28, 34, 39, 45)	Ground reference	Eight ground pins ensure low-inductance return paths, reducing simultaneous switching noise in 16-bit parallel interfaces

Key Features

Feature	Design Value
Dual independent 8-bit control	Separate 1DIR/1OE and 2DIR/2OE allow concurrent bidirectional data transfer on two isolated byte lanes
IOFF partial power-down	Outputs automatically enter high-Z when VCC = 0 V, eliminating backfeed risk during power sequencing or fault conditions
Schmitt-trigger inputs	Input hysteresis ≥0.3 V at 3.3 V supply rejects noise from automotive harnesses and relay-induced transients
5.5 V tolerant inputs	Accepts 5 V logic levels while operating from 1.2–3.6 V supply - eliminates external level translators in mixed-voltage clusters
AEC-Q100 Grade 1 qualification	Validated for −40 °C to +125 °C operation with lifetime reliability testing per automotive stress standards

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
74LVCH16245ADGV-Q100	Includes bus hold circuitry on all data inputs; identical pinout and electrical specs otherwise	Eliminates need for external pull-ups on floating data lines in low-power sleep states	Select when bus stability during MCU deep-sleep or reset is required
SN74LVC16245ADGGR	Industrial-grade (non-automotive); same functional spec but no AEC-Q100 qualification or extended temp screening	Not suitable for under-hood or safety-critical zones; lower cost for non-automotive test fixtures	Select only for bench validation or non-automotive production where AEC-Q100 is not mandated

Compared with 74LVCH16245ADGV-Q100, the 74LVC16245ADGV-Q1J lacks bus hold but offers identical AEC-Q100 Grade 1 performance and lower static current; versus SN74LVC16245ADGGR, it adds automotive qualification, tighter parametric screening, and guaranteed operation to +125 °C - essential for engine control and ADAS deployment.

FAQ

Is 74LVC16245ADGV-Q1J pin-compatible with 74LVCH16245ADGV-Q100?

Yes - both devices share identical SOT480-1 (TVSOP48) pinout, supply ranges, timing specs, and AEC-Q100 qualification. The only functional difference is that the LVCH variant includes bus hold circuitry on data inputs, while the LVC version does not. No PCB redesign is needed for substitution if bus hold is not required.

What is the maximum data rate supported by this transceiver?

Based on propagation delay (t_pd ≤ 6.0 ns at VCC = 3.3 V) and enable/disable times (t_en/t_dis ≤ 7.0 ns), the device supports reliable bidirectional data toggling up to 83 MHz (12 ns period), making it suitable for high-speed parallel control buses in automotive gateways and display interfaces.

Does this part support hot insertion or live bus connection?

Yes - the IOFF circuit ensures outputs remain in high-impedance state when VCC = 0 V, preventing back-current flow during hot-plug events. Combined with 5.5 V input tolerance, this enables safe connection to live 5 V buses even before the transceiver's supply is fully ramped.

How does the Schmitt-trigger input improve noise immunity in automotive environments?

Schmitt-trigger inputs provide ≥0.3 V hysteresis at 3.3 V supply, rejecting common-mode noise spikes and slow-rising signals from inductive loads (e.g., solenoids, motors). This prevents false triggering on CAN/LIN bus stubs or chassis-ground-referenced sensor lines subject to EMI in vehicle harnesses.
