Product details
Overview
74ALVCH162245DL:11 from Nexperia is a 16-bit CMOS bus transceiver with dual 8-bit direction control (1DIR/2DIR), dual active-low output enables (1OE/2OE), integrated 30 Ω termination resistors on all I/Os, bus hold circuitry on all data inputs, and IOFF partial power-down protection. It operates from 1.2 V to 3.6 V and supports bidirectional data flow between two 8-bit buses or one 16-bit bus in high-speed digital systems such as memory interface buffers and FPGA I/O expansion.
For engineers reviewing the 74ALVCH162245DL:11 datasheet, 74ALVCH162245DL:11 pinout, 74ALVCH162245DL:11 application, or 74ALVCH162245DL:11 equivalent, key selection criteria include its 30 Ω on-die termination for impedance matching, bus hold functionality eliminating external pull-ups, IOFF-enabled hot-swap capability, and TSSOP48 package compatibility with dense PCB layouts.
Technical Context
The device implements two independent 8-bit transceiver blocks, each with dedicated DIR and OE pins enabling granular control of data direction and output state. Its bus hold circuit maintains valid logic levels on floating inputs using ±75–175 μA hold current at 3.0 V, reducing system-level noise susceptibility.
IOFF circuitry actively disables outputs during power-down by disconnecting internal paths when VCC = 0 V, preventing backflow current up to ±50 mA per I/O-critical for mixed-voltage domain sequencing in modern embedded systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |

Pinout & Package
TSSOP48 (SOT362-1) package: 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 assembly and thermal performance in space-constrained designs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1DIR, 2DIR | Direction control input | Determines data flow direction per 8-bit block: HIGH = A→B, LOW = B→A |

| 1A0–1A7, 2A0–2A7 | Data I/O port A | First 8-bit bidirectional bus interface with bus hold and 30 Ω termination |
| 1B0–1B7, 2B0–2B7 | Data I/O port B | Second 8-bit bidirectional bus interface with identical termination and hold features |
| VCC (pins 7, 18, 31, 42) | Power supply | Four distributed VCC pins minimize IR drop and supply noise across the 48-pin array |
| GND (pins 4, 10, 15, 21, 28, 34, 39, 45) | Ground reference | Eight GND pins ensure low-inductance return paths and reduce ground bounce in fast-switching operation |
Key Features
| Feature | Design Value |

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 |
|---|---|---|---|
| SN74ALVTH162245GR | TI part with 2.5 V/3.3 V only supply range (2.3–3.6 V); no bus hold; higher ICC (max 40 μA vs. 40 μA typical) | Lacks bus hold and IOFF - requires external pull resistors and cannot support hot-swap | Select only if operating exclusively at 2.5 V/3.3 V and external hold circuitry is acceptable |
| 74LVC162245ADGG | Nexperia LVC variant: same pinout but no integrated 30 Ω termination or bus hold; wider VCC range (1.2–3.6 V) | Requires 32 external 30 Ω resistors and 16 pull resistors - increases layout complexity and cost | Choose when board-level termination is preferred for tuning or when bus hold is unnecessary |
Compared with SN74ALVTH162245GR and 74LVC162245ADGG, the 74ALVCH162245DL:11 uniquely integrates both 30 Ω termination and bus hold while retaining full 1.2–3.6 V operation and IOFF-reducing component count by ≥48 parts and enabling true hot-swap capability without design trade-offs.

FAQ
What is the function of the IOFF feature in the 74ALVCH162245DL:11?
The IOFF feature disables all outputs when VCC = 0 V, blocking reverse current flow into powered sections of the system. This prevents damage during hot-plug events or partial power-down sequences, with leakage limited to <10 μA per I/O terminal under absolute maximum conditions.
Can the 74ALVCH162245DL:11 operate at 1.8 V supply voltage?
Yes-the device is fully specified from 1.2 V to 3.6 V. At 1.8 V, VIH is 1.2 V and VIL is 0.7 V, ensuring compatibility with 1.8 V logic families. Propagation delay remains within 2.5–4.9 ns, supporting reliable operation in low-power portable and battery-operated systems.
How does the integrated 30 Ω termination resistor improve signal integrity?
The 30 Ω on-die termination matches typical PCB trace impedances in compact high-density layouts, suppressing signal reflections that cause ringing and timing violations. Unlike external resistors, it eliminates stub effects and parasitic inductance, maintaining clean edges at rise/fall times ≤2.5 ns.
Is the 74ALVCH162245DL:11 pin-compatible with standard 74-series transceivers?
No-it uses a proprietary MULTIBYTE™ flow-through pinout optimized for minimal trace length and crosstalk, differing from legacy 74-series layouts. Pin mapping follows TSSOP48 SOT362-1 mechanical outline with dedicated VCC/GND distribution, requiring specific PCB footprint design rather than drop-in replacement.
