Product details

Overview

74LVCH16245ADGG-QJ from Nexperia is a 16-bit automotive-qualified bus transceiver with dual 8-bit directional control, 3-state outputs, 5.5 V overvoltage-tolerant inputs, 1.2 V to 3.6 V supply operation, and integrated bus hold on data I/Os. It functions as a bidirectional level translator between 3.3 V and 5 V domains in engine control units and ADAS domain controllers.

For engineers reviewing the 74LVCH16245ADGG-QJ datasheet, 74LVCH16245ADGG-QJ pinout, 74LVCH16245ADGG-QJ application, or 74LVCH16245ADGG-QJ equivalent, this device supports partial power-down (IOFF), Schmitt-trigger inputs for noise immunity, AEC-Q100 Grade 1 qualification (-40 °C to +125 °C), and TSSOP48 packaging with flow-through pinout for PCB routing efficiency.

Technical Context

This transceiver implements two independent 8-bit bidirectional data paths, each controlled by dedicated direction (1DIR/2DIR) and output enable (1OE/2OE) inputs. Its IOFF circuitry actively disables outputs during power-down to prevent backflow current, satisfying automotive partial-power-down requirements.

Schmitt-trigger inputs ensure robust operation with slow-rising signals common in noisy automotive environments, while bus hold functionality on all data I/O pins (1A0–1A7, 1B0–1B7, 2A0–2A7, 2B0–2B7) eliminates external pull resistors in floating-bus scenarios.

Key Specifications

Parameter	Value and Actual Design Meaning
Supply Voltage Range	1.2 V to 3.6 V - Enables direct interface with 1.2 V, 1.8 V, 2.5 V, and 3.3 V logic systems 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 V_CC = 3.0–3.6 V - Supports high-speed data transfer in CAN/FlexRay gateway interfaces.
Bus Hold Current (I_BHL/I_IBHH)	±10 μA to ±75 μA - Maintains valid logic states on un-driven data lines without external biasing components.
IOFF Leakage Current	±10 μA max at V_CC = 0 V - Prevents damaging back-current during hot-swap or partial system power-down sequences.
ESD Protection	HBM > 2000 V, CDM > 1000 V - Meets stringent automotive ESD immunity requirements per AEC-Q100.
Operating Temperature	-40 °C to +125 °C - Qualified for under-hood and transmission-control module deployment.

Pinout & Package

TSSOP48 package (SOT362-1), 48-pin plastic thin shrink small outline, 6.1 mm body width, 0.5 mm lead pitch, exposed thermal pad not present.

Pin/Terminal	Circuit Role	Design Meaning
1DIR, 2DIR	Direction control input	Active-HIGH signal selecting data flow direction per 8-bit port (A↔B).
1OE, 2OE	Output enable input	Active-LOW control enabling/disabling respective 8-bit output groups into high-impedance state.
1A0–1A7, 2A0–2A7	Data I/O port A	First and second 8-bit bidirectional data terminals with bus hold and 5.5 V tolerance.
1B0–1B7, 2B0–2B7	Data I/O port B	Complementary 8-bit bidirectional data terminals, functionally identical to port A.
VCC (pins 7, 18, 31, 42)	Power supply	Four distributed supply pins minimize IR drop and improve noise immunity across wide operating range.
GND (pins 4, 10, 15, 21, 28, 34, 39, 45)	Ground reference	Eight ground connections reduce ground bounce and support low-noise switching performance.

Key Features

Feature	Design Value
AEC-Q100 Grade 1 qualification	Validated for automotive use from -40 °C to +125 °C ambient, including temperature cycling and humidity testing.
Dual independent 8-bit control	Separate 1DIR/1OE and 2DIR/2OE pairs allow asymmetric data flow management in multi-processor interconnects.
Bus hold on all data I/Os	Eliminates need for external pull-up/pull-down resistors on data lines, reducing BOM count and board space.
IOFF partial power-down protection	Automatically disables outputs when V_CC = 0 V, preventing reverse current damage during system sleep modes.
Schmitt-trigger inputs	Provides hysteresis (typically 0.3–0.5 V) to reject noise and accommodate slow-edge signals from sensors or legacy modules.

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
74LVC16245ADGG-Q100	No bus hold circuit; lower I_BHL/I_IBHH (0 μA); identical pinout and electrical specs otherwise.	Requires external pull resistors on floating data lines; suitable where bus stability is managed elsewhere.	Select when cost sensitivity outweighs need for internal bus hold and board space is available for external biasing.
SN74LVC16245ADGGR	Non-automotive grade; commercial temp range (-40 °C to +85 °C); same electrical specs but no AEC-Q100 validation.	Not qualified for under-hood or safety-critical automotive use; limited to infotainment or cabin modules.	Choose only for non-automotive industrial or consumer applications requiring identical functionality at lower cost.

Compared with 74LVCH16245ADGG-QJ, the 74LVC16245ADGG-Q100 lacks bus hold-increasing BOM and layout complexity-while the SN74LVC16245ADGGR omits AEC-Q100 qualification, excluding it from powertrain and ADAS deployments despite matching speed and voltage specs.

FAQ

Is 74LVCH16245ADGG-QJ pin-compatible with 74LVC16245ADGG-Q100?

Yes, both devices share identical TSSOP48 (SOT362-1) pinout, supply voltage range, and functional behavior. The sole difference is the presence of bus hold circuitry on all data I/Os in the LVCH variant, which does not affect pin mapping or electrical interface compatibility.

What is the maximum data rate supported by this transceiver?

The device does not specify a maximum clock frequency, but its propagation delay (1.0–6.0 ns) and enable/disable times (1.0–7.0 ns) support reliable operation up to approximately 100 MHz in well-terminated, low-capacitance bus configurations typical of automotive control networks.

Can 74LVCH16245ADGG-QJ be used with a 1.2 V supply and 5 V inputs simultaneously?

Yes. The device operates from 1.2 V to 3.6 V and tolerates input voltages up to 5.5 V regardless of V_CC. This allows safe interfacing of 5 V peripherals to a 1.2 V core logic domain without external clamping or level-shifting circuitry.

Does the IOFF feature require external circuitry to activate?

No. IOFF is fully automatic: when V_CC drops to 0 V, the output drivers are internally disabled, forcing all I/Os into high-impedance state. No external control signal or configuration is needed-this behavior is inherent to the silicon design and verified per AEC-Q100 test conditions.
