Product details
Overview
74LVC162245ADGG-QJ from Nexperia is a 16-bit dual-directional bus transceiver with integrated 30 Ω series termination resistors, 3-state outputs, dual direction (1DIR/2DIR) and dual output enable (1OE/2OE) controls, and 5.5 V tolerant I/Os operating from 1.2 V to 3.6 V supply. It supports mixed-voltage translation between 3.3 V and 5 V systems and is qualified to AEC-Q100 Grade 1 for automotive use.
For engineers reviewing the 74LVC162245ADGG-QJ datasheet, 74LVC162245ADGG-QJ pinout, 74LVC162245ADGG-QJ application, or 74LVC162245ADGG-QJ equivalent, this device delivers deterministic bidirectional data flow control, IOFF-enabled partial power-down protection, Schmitt-trigger inputs for noise immunity, and TSSOP48 packaging optimized for high-density PCB layouts in automotive infotainment and ADAS domain controllers.
Technical Context
This transceiver implements two independent 8-bit bidirectional channels, each with dedicated DIR and OE pins enabling granular control of data direction and output state. Its IOFF circuitry actively disables outputs during power-down, preventing backflow current when VCC = 0 V - critical for hot-swap and multi-rail system integrity.
The integrated 30 Ω series termination resistors reduce signal reflections on high-speed parallel buses, while Schmitt-trigger inputs tolerate slow edge rates (down to 20 ns/V at 1.2 V), supporting legacy TTL-level interfacing without external hysteresis components.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.2 V to 3.6 V - enables operation across low-power microcontroller I/O domains and standard 3.3 V logic rails. |
| I/O Voltage Tolerance | Up to 5.5 V - allows direct connection to 5 V peripherals without level-shifting circuitry. |
| Propagation Delay | 1.0 ns to 8.5 ns (VCC = 3.0–3.6 V) - supports >100 MHz bus timing margins in DDR-adjacent applications. |
| Termination Resistance | 30 Ω series per I/O - matches typical PCB trace impedance to suppress ringing on 50–75 Ω transmission lines. |
| IOFF Leakage Current | ±10 μA max at VCC = 0 V - ensures safe isolation during power sequencing in multi-voltage automotive ECUs. |
| Operating Temperature | −40 °C to +125 °C - meets AEC-Q100 Grade 1 requirements for under-hood and cockpit electronics. |
| ESD Protection | HBM >2000 V, CDM >1000 V - sustains handling and board assembly without additional protection devices. |
Pinout & Package
TSSOP48 package (SOT362-1): plastic thin shrink small outline, 48 leads, 6.1 mm body width, 0.5 mm lead pitch, 1.2 mm max height - optimized for automated SMT placement and thermal dissipation in space-constrained automotive modules.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1DIR, 2DIR | Direction control input (active HIGH) | Determines data flow direction per 8-bit channel: HIGH = A→B, LOW = B→A. |
| 1OE, 2OE | Output enable input (active LOW) | Asserting LOW enables corresponding 8-bit outputs; HIGH forces high-impedance state. |
| 1A0–1A7, 2A0–2A7 | Port A data I/O (channel 1 & 2) | First set of 16 bidirectional data terminals; internally connected to 30 Ω series resistors. |
| 1B0–1B7, 2B0–2B7 | Port B data I/O (channel 1 & 2) | Second set of 16 bidirectional data terminals; identical termination and voltage tolerance as Port A. |
| VCC | Power supply | Single 1.2–3.6 V rail powers all logic and I/O circuits; four dedicated pins minimize IR drop. |
| GND | Ground reference | Eight GND pins distributed across package for low-inductance return paths and reduced ground bounce. |
Key Features
| Feature | Design Value |
|---|---|
| Dual 8-bit channel architecture | Independent DIR/OE control per channel enables concurrent bidirectional transfers on separate buses (e.g., CAN FD interface + sensor hub). |
| Integrated 30 Ω series termination | Eliminates need for 32 discrete 0402 resistors, reducing BOM count, layout area, and signal path discontinuities. |
| IOFF partial power-down | Prevents destructive back-current when VCC is unpowered but I/Os remain driven - essential for modular ECU designs with staggered power sequencing. |
| Schmitt-trigger inputs | Provides 0.5 V hysteresis (typ.) enabling reliable sampling of slow-rising signals from mechanical switches or legacy sensors without external conditioning. |
| AEC-Q100 Grade 1 qualification | Validated for continuous operation at +125 °C ambient, supporting placement near power converters or engine control units. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit bidirectional transceiver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC162245ADGGR | Non-automotive grade; rated −40 °C to +85 °C only; no AEC-Q100 qualification. | Lacks IOFF and extended temperature support - unsuitable for under-hood or safety-critical modules. | Select only for cost-sensitive industrial or consumer applications where automotive reliability is not required. |
| 74AVC162245ZQLR | Lower VCC range (1.2–3.6 V same), but no integrated termination resistors; higher drive strength (24 mA vs 12 mA). | Requires 32 external 30 Ω resistors; better suited for high-speed DDR memory interfaces than automotive bus bridging. | Choose when maximum speed (>150 MHz) is prioritized over BOM simplification and EMI reduction. |
Compared with SN74LVC162245ADGGR and 74AVC162245ZQLR, the 74LVC162245ADGG-QJ uniquely combines AEC-Q100 Grade 1 qualification, integrated 30 Ω termination, and IOFF protection - making it the only option qualified for automotive powertrain and ADAS subsystems requiring zero external components and guaranteed fail-safe behavior during power transitions.

FAQ
Does 74LVC162245ADGG-QJ support hot-swap operation?
Yes. Its IOFF circuitry actively disables outputs when VCC = 0 V, limiting back-current to ±10 μA max. This prevents damage during live insertion/removal in modular automotive ECUs, provided I/O voltages remain within −0.5 V to 5.5 V limits per the datasheet's absolute maximum ratings.
Can this transceiver replace discrete 74LVC245-based designs without layout changes?
No. While functionally equivalent to two 74LVC245s, the 74LVC162245ADGG-QJ uses a 48-pin TSSOP package with non-mirrored pinout and integrated termination. Direct replacement requires PCB redesign to accommodate the larger footprint and revised routing for dual DIR/OE control and distributed GND/VCC pins.
What is the maximum data rate supported with integrated 30 Ω termination?
Measured propagation delay is 1.0–5.7 ns (VCC = 3.0–3.6 V), supporting reliable operation up to 100 MHz bus clocks. The 30 Ω resistors optimize signal integrity on 50–75 Ω PCB traces up to 15 cm length; beyond that, external termination or controlled-impedance routing is recommended.
How does Schmitt-trigger input hysteresis improve system robustness?
Schmitt-trigger inputs provide ~0.5 V hysteresis (typ.), rejecting noise spikes and slow edges from inductive loads like relays or motors. This eliminates false triggering in body control modules where switch inputs share harnesses with high-current actuators, reducing firmware debounce overhead by up to 70%.
