Product details
Overview
74LVC16245AEV-Q10Y from Nexperia is an automotive-qualified 16-bit bus transceiver with dual 8-bit directional control, 3-state outputs, 5 V-tolerant inputs (up to 5.5 V), 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. Used in automotive body control modules for bidirectional data routing between microcontrollers and peripheral clusters.
For engineers reviewing the 74LVC16245AEV-Q10Y datasheet, 74LVC16245AEV-Q10Y pinout, 74LVC16245AEV-Q10Y application, or 74LVC16245AEV-Q10Y equivalent, key selection criteria include AEC-Q100 Grade 1 qualification (-40 °C to +125 °C), dual OE/DIR control per 8-bit port, 5.5 V input tolerance, IOFF-enabled safe power sequencing, and TSSOP48/TVSOP48 package compatibility with high-density PCB layouts.
Technical Context
This transceiver implements a dual-channel flow-through architecture: two independent 8-bit bidirectional ports (Port A and Port B), each controlled by dedicated DIR (direction) and OE (output enable) signals. Direction logic determines data flow (A→B or B→A), while active-low OE forces outputs into high-impedance state-enabling bus sharing without contention.
IOFF circuitry disables outputs when VCC = 0 V, blocking backflow current during partial power-down-a critical requirement for automotive domain controllers with staggered supply sequencing. Schmitt-trigger inputs ensure robust operation with slow-rising signals common in automotive sensor interfaces and legacy bus systems.
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 domains. |
| Input Voltage Tolerance | Up to 5.5 V - Allows safe connection to 5 V peripherals without level-shifting circuitry. |
| Propagation Delay (tpd) | 1.0 ns (min) to 6.0 ns (max) at VCC = 3.3 V - Supports high-speed bidirectional data transfer up to ~100 MHz system clock domains. |
| IOFF Leakage Current | ±10 μA max at VCC = 0 V - Ensures <100 μW standby power during partial shutdown, meeting automotive ASAM/UDS sleep-mode requirements. |
| ESD Protection | HBM >2000 V, CDM >1000 V - Meets stringent automotive ESD immunity standards for under-hood and cabin electronics. |
| Operating Temperature | -40 °C to +125 °C - Qualified per AEC-Q100 Grade 1 for engine control units, ADAS sensor hubs, and infotainment gateways. |
| Output Drive Strength | ±24 mA at VCC = 3.0 V - Sufficient to drive 15 pF loads over 10 cm traces in CAN/LIN sub-bus applications. |
Pinout & Package
TSSOP48 (SOT362-1) and TVSOP48 (SOT480-1) packages: 48-pin surface-mount, 6.1 mm (TSSOP) or 4.4 mm (TVSOP) body width, 0.5 mm (TSSOP) or 0.4 mm (TVSOP) lead pitch. Both feature multiple GND/VCC pins for low-noise operation and reduced ground bounce.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1DIR, 2DIR | Direction control input (active HIGH) | Determines data flow direction per 8-bit port: HIGH = A→B, LOW = B→A. |
| 1OE, 2OE | Output enable input (active LOW) | Disables corresponding 8-bit port outputs to high-impedance state for bus arbitration. |
| 1A0–1A7, 2A0–2A7 | Port A / Port B data I/O | Bidirectional data terminals; internally connected to transceiver core with bus-hold (LVCH variant only). |
| 1B0–1B7, 2B0–2B7 | Port A / Port B data I/O | Complementary I/O set for each port; identical electrical behavior to A-side pins. |
| VCC (Pins 7, 18, 31, 42) | Power supply | Four distributed VCC pins minimize IR drop and improve PSRR across wide operating temperature range. |
| GND (Pins 4, 10, 15, 21, 28, 34, 39, 45) | Ground reference | Eight GND pins provide low-inductance return paths, reducing simultaneous switching noise in multi-port systems. |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent 8-bit control | Enables asymmetric bus management: e.g., Port 1 for CAN controller ↔ transceiver, Port 2 for LIN cluster ↔ MCU. |
| IOFF partial power-down | Prevents destructive back-current when one side of the bus is powered while the other is off-critical for domain controller hot-swap compliance. |
| Schmitt-trigger inputs | Input hysteresis ≥0.3 V ensures reliable sampling of noisy analog-like signals (e.g., wake-up lines, switch inputs) without external filtering. |
| 5.5 V tolerant inputs | Eliminates need for discrete voltage translators when interfacing legacy 5 V sensors or displays to modern 3.3 V SoCs. |
| MULTIBYTE flow-through pinout | Standardized A/B pairing (e.g., 1A0/1B0 adjacent) simplifies PCB layout, reduces trace skew, and eases signal integrity validation. |
Applications
| Automotive Body Control Module | ADAS Sensor Hub Interface |

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; otherwise identical electrical specs and pinout. | Preferred where floating inputs must be prevented without external pull-ups (e.g., unpopulated test points, hot-plug connectors). | Select when input stability during idle states is critical; adds ~5 μA per pin static current vs. LVC version. |
| SN74LVC16245ADGGR | Non-automotive grade (industrial temp: -40 °C to +85 °C); same pinout and DC specs but no AEC-Q100 qualification. | Suitable for non-safety-critical infotainment accessories or development boards where automotive qualification is not required. | Choose for cost-sensitive prototyping or Tier-2 consumer-grade vehicle accessories lacking functional safety requirements. |
Compared with 74LVCH16245ADGV-Q100, the 74LVC16245AEV-Q10Y lacks bus-hold but offers lower static power; versus SN74LVC16245ADGGR, it provides full AEC-Q100 Grade 1 compliance essential for powertrain and chassis ECUs-making it the only qualified option for ASIL-B-relevant signal routing.

FAQ
Is 74LVC16245AEV-Q10Y pin-compatible with standard 74LVC16245A packages?
Yes-74LVC16245AEV-Q10Y uses the same TSSOP48 (SOT362-1) and TVSOP48 (SOT480-1) footprints as industrial-grade variants. Pin numbering, signal mapping, and mechanical dimensions match exactly, enabling drop-in replacement in existing AEC-Q100-compliant designs without PCB rework.
Does this device support hot insertion in live automotive buses?
Yes-its IOFF circuitry actively disables outputs when VCC drops below threshold, preventing back-current injection into powered bus segments. Combined with 5.5 V input tolerance and ±2000 V HBM ESD rating, it meets ISO 10605 requirements for hot-plug resilience in 12 V vehicle architectures.
What is the maximum data rate supported in bidirectional mode?
Based on tpd ≤ 6.0 ns (max) and tdis/ten ≤ 7.0 ns (max) at VCC = 3.3 V, the device supports reliable burst-mode transfers up to 80 Mbps with proper termination. For sustained streaming, derate to 60 Mbps to accommodate setup/hold margins and PCB trace losses.
How does the Schmitt-trigger input improve noise immunity in automotive environments?
Schmitt-trigger inputs provide ≥0.3 V hysteresis, rejecting common-mode noise spikes up to 300 mV amplitude-critical for surviving alternator ripple, ignition coil transients, and RF coupling in engine compartments. This eliminates need for external RC filters on wake-up or diagnostic lines.
