Product details

Overview

74LVC16245ADGG-Q1J from Nexperia is an automotive-qualified 16-bit dual 8-bit bus transceiver with independent direction and output-enable controls, 3-state outputs, 5.5 V overvoltage-tolerant inputs, 1.2 V to 3.6 V supply range, and IOFF partial power-down protection. It enables bidirectional data flow between mixed-voltage domains (e.g., 3.3 V microcontroller and 5 V peripheral) in engine control units and ADAS domain controllers.

For engineers reviewing the 74LVC16245ADGG-Q1J datasheet, 74LVC16245ADGG-Q1J pinout, 74LVC16245ADGG-Q1J application, or 74LVC16245ADGG-Q1J equivalent, this page delivers verified functional architecture, TSSOP48 pin mapping, AEC-Q100 Grade 1 thermal validation (−40 °C to +125 °C), Schmitt-trigger noise immunity, and bus hold capability (in LVCH variant).

Technical Context

This device implements two independent 8-bit transceiver blocks (1A/1B and 2A/2B), each with dedicated DIR and OE pins enabling granular control of data direction and output state. Its dual-OE architecture allows selective disabling of either 8-bit port without affecting the other, supporting flexible memory-mapped I/O partitioning.

Schmitt-trigger inputs ensure robust operation with slow-rising signals (e.g., from mechanical sensors), while the IOFF circuit actively disables outputs during power-down to prevent backflow current-critical for hot-swap and low-power sleep modes in automotive ECUs.

Key Specifications

Parameter	Value and Actual Design Meaning
Supply Voltage Range	1.2 V to 3.6 V - supports direct interface with 1.8 V, 2.5 V, and 3.3 V logic families without level shifters
Input Overvoltage Tolerance	Up to 5.5 V - enables 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 - ensures timing compliance in high-speed CAN/LIN gateway data paths
IOFF Leakage Current	±10 μA max at V_CC = 0 V - guarantees <100 μW standby power in partial power-down mode
Ambient Temperature Range	−40 °C to +125 °C - qualified per AEC-Q100 Grade 1 for under-hood automotive deployment
ESD Protection	HBM >2000 V, CDM >1000 V - meets automotive board-level ESD robustness requirements
Output Drive Strength	±24 mA at V_CC = 3.0 V - sufficient to drive 50 pF loads across 15 cm PCB traces in distributed control modules

Pinout & Package

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

Pin/Terminal	Circuit Role	Design Meaning
1DIR, 2DIR	Direction control input	Active-HIGH signal selects data flow direction per 8-bit port (A→B or B→A)
1OE, 2OE	Output enable input (active LOW)	Independent 3-state control for each 8-bit port; HIGH forces high-impedance output
1A0–1A7, 2A0–2A7	Data I/O port A	First and second 8-bit bidirectional data bus segment connected to controller side
1B0–1B7, 2B0–2B7	Data I/O port B	First and second 8-bit bidirectional data bus segment connected to peripheral/memory side
VCC (pins 7, 18, 31, 42)	Power supply	Four distributed VCC pins minimize IR drop and supply noise in high-current switching
GND (pins 4, 10, 15, 21, 28, 34, 39, 45)	Ground reference	Eight GND pins provide low-inductance return paths, reducing ground bounce in multi-bit switching

Key Features

Feature	Design Value
Dual independent 8-bit transceivers	Enables split-bus arbitration in multi-master systems without external logic or timing constraints
IOFF partial power-down	Prevents destructive backflow current when V_CC is off but I/O lines remain energized (e.g., during ECU sleep/wake transitions)
Schmitt-trigger inputs	Accepts slow-rising signals down to 10 ns/V transition rate-compatible with legacy analog sensor interfaces
5.5 V tolerant inputs	Eliminates need for external voltage translators when interfacing with 5 V legacy peripherals in modern 3.3 V domains
MULTIBYTE flow-through pinout	Minimizes PCB trace skew and crosstalk by aligning complementary A/B signals in adjacent pins

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
74LVCH16245ADGG-Q100	Includes bus hold circuitry on all data inputs (74LVC variant lacks bus hold)	Preferred where input floating states must be prevented without external pull resistors (e.g., hot-plug connectors)	Select when system-level reliability requires automatic input state retention during signal glitches or disconnection
SN74LVC16245ADGGR	Industrial-grade (−40 °C to +85 °C), non-AEC-Q100 qualified, same pinout and electrical specs	Suitable for non-automotive industrial control panels where AEC qualification is unnecessary	Choose for cost-sensitive non-automotive designs requiring identical functionality without automotive qualification overhead

Compared with 74LVC16245ADGG-Q1J, the LVCH variant adds bus hold for floating-input resilience but shares identical timing, voltage, and thermal specs; the SN74LVC16245ADGGR offers identical performance at lower qualification cost for non-automotive use.

FAQ

Is 74LVC16245ADGG-Q1J pin-compatible with 74LVCH16245ADGG-Q100?

Yes-both devices share identical TSSOP48 pinout (SOT362-1), same VCC/GND distribution, and functionally equivalent DIR/OE/data pin assignments. The only difference is internal bus hold circuitry on the LVCH variant, which does not affect pin mapping or external connections.

What is the maximum data rate supported by this transceiver?

Based on propagation delay (t_pd ≤ 6.0 ns at V_CC = 3.0–3.6 V) and enable/disable times (≤ 7.0 ns), the device supports reliable operation up to 80 MHz bus clock rates in worst-case conditions, assuming 50 pF load and proper termination.

Does this part support hot insertion in live backplanes?

Yes-the IOFF circuitry ensures outputs enter high-impedance state when V_CC = 0 V, and 5.5 V input tolerance allows safe connection to powered-backplane signals before V_CC ramp-up, meeting JEDEC JESD78 Class II latch-up immunity requirements.

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

Schmitt-trigger inputs provide 0.3–0.5 V hysteresis (depending on V_CC), rejecting common-mode noise spikes up to ±300 mV on data lines-critical for surviving conducted emissions from alternators, ignition systems, and DC-DC converters in vehicle harnesses.
