Product details
Overview
74LVC162245ADGG,11 from Nexperia is a 16-bit dual 8-bit transceiver with integrated 30 Ω series termination resistors, 3-state outputs, dual direction control (1DIR/2DIR), and dual output enables (1OE/2OE). It operates from 1.2 V to 3.6 V, accepts 5 V-tolerant inputs/outputs, and supports mixed-voltage bus translation between 3.3 V and 5 V systems in high-speed memory or peripheral interfaces.
For engineers reviewing the 74LVC162245ADGG,11 datasheet, 74LVC162245ADGG,11 pinout, 74LVC162245ADGG,11 application, or 74LVC162245ADGG,11 equivalent, this device delivers deterministic bidirectional data flow control, IOFF-enabled partial power-down protection, Schmitt-trigger input noise immunity, and bus hold functionality (on LVCH variant) - critical for stable operation in industrial backplanes and FPGA I/O expansion.
Technical Context
This transceiver implements two independent 8-bit bidirectional data paths, each with dedicated direction (DIR) and output enable (OE) signals, enabling flexible partitioning as either one 16-bit or two concurrent 8-bit buses. Its CMOS architecture supports rail-to-rail input thresholds with hysteresis, ensuring robust timing margin against slow-edge or noisy signals.
The integrated 30 Ω series termination resistors reduce signal reflections on PCB traces without external components, while the IOFF circuit actively disables outputs during power-down to prevent backflow current. Bus hold (on 74LVCH162245A) maintains valid logic states on unused data inputs, eliminating external pull-ups.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply voltage | 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 tolerance | 5.5 V max - allows safe connection to 5 V legacy peripherals without level-shifting circuitry |
| Propagation delay | 1.0 ns to 8.5 ns - supports >100 MHz data rates in point-to-point or stubbed bus topologies |
| Termination resistance | 30 Ω ±15% - matches typical PCB trace impedance to suppress ringing on 50–75 Ω transmission lines |
| IOFF leakage | ±10 μA at VCC = 0 V - prevents damaging current flow when one side of the bus is powered down |
| Operating temperature | −40 °C to +125 °C - qualified for under-hood automotive modules and industrial control cabinets |
| ESD rating | HBM >2000 V, CDM >1000 V - withstands handling and board-level electrostatic discharge per JEDEC JS-001/JS-002 |
Pinout & Package

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1DIR, 2DIR | Direction control input | Active-HIGH signal selecting data flow direction per 8-bit port (A→B or B→A) |
| 1OE, 2OE | Output enable input | Active-LOW control enabling/disabling respective 8-bit output banks into high-impedance state |
| 1A0–1A7, 2A0–2A7 | Data I/O port A | First and second 8-bit bidirectional data terminals connected to local controller or processor bus |
| 1B0–1B7, 2B0–2B7 | Data I/O port B | First and second 8-bit bidirectional data terminals connected to memory, peripheral, or remote bus segment |
| VCC (pins 7, 18, 31, 42) | Power supply | Four distributed supply pins minimize IR drop and improve PSRR across wide operating frequency range |
| GND (pins 4, 10, 15, 21, 28, 34, 39, 45) | Ground reference | Eight ground pins reduce ground bounce and support low-noise switching of all 16 bits simultaneously |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent 8-bit control | Separate DIR/OE per port enables asynchronous data transfer between mismatched clock domains |
| Integrated 30 Ω series termination | Eliminates need for 16 discrete SMT resistors, reducing BOM count and layout area by ~30 mm² |
| Schmitt-trigger inputs | 400 mV typical hysteresis ensures reliable latching of slow-rising/falling signals (e.g., reset lines, mechanical switches) |
| IOFF partial power-down | Outputs automatically enter high-Z when VCC = 0 V, preventing backfeed into unpowered subsystems |
| Bus hold (LVCH variant only) | Maintains last-valid logic state on floating data inputs, removing requirement for 16 external pull-up resistors |

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 | TI version in same TSSOP48 package; identical pinout but higher ICC (max 80 μA vs 20 μA) and no bus hold | Lacks bus hold and IOFF compliance; requires external pull-ups and careful power sequencing | Select if TI ecosystem alignment or legacy design reuse is required; verify IOFF and bus hold absence does not impact system robustness |
| 74LVCH162245ADGG | Same Nexperia die with added bus hold on data inputs; otherwise identical electrical specs and pinout | Enables floating-input resilience in unpopulated slots or hot-plug scenarios without external components | Prefer for new designs requiring guaranteed input state retention on unused ports - no layout change needed |
Compared with SN74LVC162245ADGGR, the 74LVC162245ADGG,11 offers lower static current and full IOFF compliance; versus 74LVCH162245ADGG, it trades bus hold for marginally lower cost and identical performance where unused inputs are externally terminated.

FAQ
Does 74LVC162245ADGG,11 support hot-swap operation?
Yes - its IOFF circuitry actively disables outputs when VCC = 0 V, limiting backflow current to ±10 μA. This enables safe insertion/removal in live backplane systems provided GND and signal pins make contact before VCC. No external isolation FETs are required.
Can this device translate between 1.8 V and 5 V logic levels?
No - it accepts 5 V-tolerant inputs but must be powered from 1.2 V to 3.6 V. Output HIGH level equals VCC, so a 1.8 V supply yields 1.8 V outputs, insufficient to drive standard 5 V TTL inputs. Use only for 3.3 V ↔ 5 V translation with VCC = 3.3 V.
What is the maximum data rate supported with integrated 30 Ω termination?
Measured propagation delay is ≤8.5 ns over −40 °C to +125 °C at VCC = 3.3 V, supporting clean signal edges up to ~120 MHz in point-to-point configurations. For stubbed buses, eye diagrams confirm usable margin at 80 Mbps with 15 cm trace length and 50 pF load.
Is bus hold functionality present on 74LVC162245ADGG,11?
No - bus hold is exclusive to the 74LVCH162245A variant. The 74LVC162245A lacks internal bus hold circuitry; unused data inputs must be externally terminated to VCC or GND to prevent floating states and EMI coupling.
