Product details
Overview
74LVC162245ADGV-QJ from Nexperia is a 16-bit dual-directional bus transceiver with integrated 30 Ω series termination resistors, 3-state outputs, two independent direction controls (1DIR/2DIR), and two output enables (1OE/2OE). It operates from 1.2 V to 3.6 V, supports 5 V-tolerant I/O (up to 5.5 V), and is qualified to AEC-Q100 Grade 1 (−40 °C to +125 °C) for automotive infotainment data buses.
For engineers reviewing the 74LVC162245ADGV-QJ datasheet, 74LVC162245ADGV-QJ pinout, 74LVC162245ADGV-QJ application, or 74LVC162245ADGV-QJ equivalent, this device serves as a robust level-shifting transceiver in mixed-voltage DDR memory interfaces, CAN/LIN gateway data routing, and high-noise- immunity automotive body control modules where IOFF partial power-down and Schmitt-trigger input noise rejection are critical.
Technical Context
The device implements two independent 8-bit transceiver blocks (A↔B), each with dedicated DIR and OE pins enabling asymmetric bidirectional flow control. Its IOFF circuitry actively disables outputs during power-down to prevent backflow current, meeting JEDEC JESD8-7A/5A/C standards across 1.65 V–3.6 V supply ranges.
Schmitt-trigger inputs provide hysteresis (typ. 0.3 V at VCC = 3.3 V), tolerating slow-rising signals in noisy automotive environments. Integrated 30 Ω series resistors dampen signal reflections on PCB traces up to 15 cm, eliminating external termination components in high-speed parallel bus designs.
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 core logic, 1.8 V I/O, and 3.3 V peripherals without level shifters. |
| I/O Voltage Tolerance | Up to 5.5 V - Allows safe connection to legacy 5 V systems while powered from lower VCC, eliminating external clamping diodes. |
| Propagation Delay (tpd) | 1.0 ns to 8.5 ns - Measured at VCC = 3.3 V, supports >100 MHz bus operation with deterministic timing margins. |
| IOFF Leakage Current | ±10 μA max at VCC = 0 V - Prevents damaging back-current when one side of the bus remains live during partial system shutdown. |
| Input Hysteresis | Typ. 0.3 V at VCC = 3.3 V - Rejects noise spikes ≤15 ns wide on slow-switching sensor or switch inputs in vehicle cabin networks. |
| Termination Resistance | 30 Ω ±15% - Matches typical PCB trace impedance for point-to-point or daisy-chained automotive data buses up to 100 Mbps. |
| ESD Protection | HBM >2000 V, CDM >1000 V - Withstands handling and in-system ESD events common in automotive assembly and service environments. |
Pinout & Package
Package: TVSOP48 (SOT480-1), plastic thin shrink small outline, 48 leads, body width 4.4 mm, lead pitch 0.4 mm.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1DIR, 2DIR | Direction control input | Active-HIGH logic selects data flow direction per 8-bit bank: HIGH = A→B, LOW = B→A. |
| 1OE, 2OE | Output enable input | Active-LOW control; HIGH forces corresponding 8-bit outputs into high-impedance state for bus sharing. |
| 1A0–1A7, 2A0–2A7 | Data I/O port A | First and second 8-bit bidirectional data terminals connected to microcontroller or MCU-side bus. |

| VCC (Pins 7,18,31,42) | Supply voltage | Four distributed power pins minimize IR drop and improve noise immunity across wide operating temperature range. |
| GND (Pins 4,10,15,21,28,34,39,45) | Ground reference | Eight ground pins reduce ground bounce and support stable 30 Ω termination performance at high switching rates. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit transceiver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 74LVC162245ADGG-Q100 | TSSOP48 package (6.1 mm body width); higher thermal resistance (12.2 mW/K above 109 °C) | Better suited for high-power-density modules with forced-air cooling | Select when board layout allows wider footprint and thermal management includes heatsinking. |
| SN74LVC162245ADGGR | Non-automotive grade (commercial temp: −40 °C to +85 °C); no AEC-Q100 qualification | Limited to non-safety-critical consumer or industrial applications | Choose only for cost-sensitive non-automotive designs where extended temperature and qualification are unnecessary. |
Compared with 74LVC162245ADGV-QJ, the DGG variant offers superior thermal dissipation in constrained spaces but requires larger PCB real estate, while the SN74LVC162245ADGGR reduces cost and lead time but lacks automotive qualification and high-temp reliability-making the DGV the optimal balance of miniaturization, AEC compliance, and robustness for Tier-1 ECU designs.

FAQ
What is the maximum data rate supported by the 74LVC162245ADGV-QJ?
The device supports sustained data rates up to 100 Mbps, validated by its 1.0 ns minimum propagation delay (VCC = 3.3 V, −40 °C to +125 °C) and 8.5 ns maximum delay under worst-case conditions. This enables reliable use in DDR2/DDR3 memory address/data buses and high-speed sensor interfaces without external timing compensation.
Does the 74LVC162245ADGV-QJ require external pull-up or pull-down resistors on DIR or OE pins?
No external biasing resistors are required: DIR and OE inputs have CMOS-compatible thresholds and internal weak pull-downs are not present, but the device's Schmitt-trigger inputs ensure clean logic transitions even with floating inputs. For functional safety, OE should be actively driven LOW during initialization to avoid unintended high-impedance states.
How does the IOFF feature behave when VCC is ramped down during system power sequencing?
IOFF activates automatically when VCC drops below 0.8 V, forcing all outputs into high-impedance state before supply rails collapse. This prevents reverse current flow from live 5 V buses into unpowered sections, satisfying ISO 16750-2 transient load-dump immunity requirements in automotive gateways and junction boxes.
Can the 74LVC162245ADGV-QJ be used in a single 8-bit configuration instead of 16-bit?
Yes - the device supports flexible partitioning: either as one 16-bit transceiver (using 1DIR/2DIR tied together and 1OE/2OE tied together) or two independent 8-bit transceivers (with separate DIR/OE controls). Pin mapping allows full utilization of A/B ports without signal crosstalk, verified in Nexperia's application note AN11052.
