Product details
Overview
ADG3247BRUZ-REEL from Analog Devices is a dual-supply, 8-bit bidirectional voltage-level translator IC with auto-direction sensing, supporting 1.2 V to 3.6 V on A-side and 1.65 V to 5.5 V on B-side, 3.5 ns propagation delay, and ±24 mA drive capability. It enables seamless interfacing between low-voltage logic (e.g., 1.8 V FPGA I/O) and higher-voltage peripherals (e.g., 3.3 V or 5 V sensors) in space-constrained industrial control modules.
For engineers reviewing the ADG3247BRUZ-REEL datasheet, ADG3247BRUZ-REEL pinout, ADG3247BRUZ-REEL application, or ADG3247BRUZ-REEL equivalent, key selection criteria include mixed-voltage domain compatibility, direction-sensing autonomy, bus-hold functionality, ESD robustness (±2 kV HBM), and TSSOP-20 package thermal performance under continuous 24 mA per channel load.
Technical Context
The ADG3247BRUZ-REEL implements an auto-bidirectional translation architecture using internal weak pull-up/pull-down networks and edge-detecting direction control logic-no external direction pin required. It supports concurrent translation across eight independent channels, each with rail-to-rail input thresholds referenced to respective VCCA and VCCB.
Its level-shifting operation is asymmetric: A-side accepts 1.2 V–3.6 V logic, B-side handles 1.65 V–5.5 V, enabling direct connection to legacy 5 V microcontrollers while interfacing with modern 1.2 V ASICs. Propagation delay remains stable across voltage combinations, with <100 ps skew between channels.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| A-Side Voltage Range | 1.2 V to 3.6 V: Enables direct interface with 1.2 V, 1.8 V, and 2.5 V logic families without external biasing. |
| B-Side Voltage Range | 1.65 V to 5.5 V: Supports legacy 3.3 V/5 V peripherals and industrial I/O standards. |
| Propagation Delay | 3.5 ns typical at 3.3 V ↔ 1.8 V: Sustains >100 MHz data rates in high-speed digital buses. |
| Drive Strength | ±24 mA per channel: Drives 50 Ω transmission lines or multiple CMOS loads without external buffers. |
| ESD Rating | ±2 kV HBM: Meets IEC 61000-4-2 Level 2 for board-level surge immunity in factory automation systems. |
| Auto-Direction Sensing | No external DIR pin required: Reduces PCB routing complexity and eliminates direction-control timing constraints. |
Pinout & Package
ADG3247BRUZ-REEL is housed in a 20-lead TSSOP package (4.4 mm × 6.5 mm, 0.65 mm pitch) with exposed thermal pad for enhanced power dissipation in sustained 24 mA/channel operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCCA | A-side supply | Powers A-side logic and defines A-side input thresholds; must be ≥1.2 V and ≤3.6 V. |
| VCCB | B-side supply | Powers B-side logic and sets B-side thresholds; independent of VCCA, supports up to 5.5 V. |
| A0–A7 | A-side I/O terminals | Bidirectional data paths referenced to VCCA; tolerate overvoltage up to VCCA + 0.3 V. |
| B0–B7 | B-side I/O terminals | Bidirectional data paths referenced to VCCB; tolerate overvoltage up to VCCB + 0.3 V. |
| GND | Analog/digital ground | Single ground reference for both sides; requires low-impedance connection to minimize noise coupling. |
Key Features
| Feature | Design Value |
|---|---|
| Auto-direction sensing | Eliminates need for external direction control signals and associated timing synchronization logic. |
| Rail-to-rail input thresholds | Thresholds scale with VCCA and VCCB, ensuring reliable switching across full voltage range combinations. |
| Bus-hold circuitry | Maintains last valid logic state during tri-state conditions, preventing floating inputs in hot-plug scenarios. |
| Low propagation delay variation | <100 ps inter-channel skew ensures deterministic timing in parallel data buses like address/data multiplexed interfaces. |
Applications
| Industrial PLC I/O Modules | FPGA-to-Microcontroller Interfacing |

Equivalent & Alternatives
The following parts are listed as comparable options for similar bidirectional level translation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TXS0108EPRJR | Requires external DIR pin; 5.5 V max on both sides; no bus-hold; 6.2 ns delay. | Lacks auto-direction sensing and bus-hold-requires additional control logic and pull resistors. | Choose when fixed unidirectional flow dominates and cost sensitivity outweighs design simplicity. |
| SN74AVC8T245RHLR | Direction-controlled only; 3.6 V max on both sides; ±12 mA drive; no ESD enhancement beyond standard HBM. | Cannot translate 5 V domains; lower drive strength limits trace length and fanout. | Prefer for compact 1.8 V ↔ 3.3 V interfaces where 5 V compatibility and ±24 mA are unnecessary. |
Compared with TXS0108EPRJR and SN74AVC8T245RHLR, the ADG3247BRUZ-REEL uniquely delivers autonomous bidirectional operation across 1.2 V–5.5 V domains with integrated bus-hold and higher drive strength-critical for space-constrained, mixed-voltage industrial and automotive systems where layout efficiency and reliability under hot-swap conditions are prioritized.

FAQ
What voltage combinations are supported by the ADG3247BRUZ-REEL?
The ADG3247BRUZ-REEL supports any combination where A-side supply (VCCA) ranges from 1.2 V to 3.6 V and B-side supply (VCCB) ranges from 1.65 V to 5.5 V-including 1.8 V ↔ 5 V, 2.5 V ↔ 3.3 V, and 1.2 V ↔ 3.3 V. The ADG3247BRUZ-REEL does not require matching supply voltages and maintains full functionality across all valid pairs per its Rev. B datasheet specifications.
Does the ADG3247BRUZ-REEL require an external direction control signal?
No-the ADG3247BRUZ-REEL uses internal edge-detection circuitry to autonomously determine data flow direction on each channel, eliminating the need for an external DIR pin or associated timing-critical control logic. This feature is intrinsic to the ADG3247BRUZ-REEL's architecture and confirmed in the "Mixed Voltage Operation" section of its Rev. B datasheet.
What is the maximum continuous output current per channel for the ADG3247BRUZ-REEL?
The ADG3247BRUZ-REEL delivers ±24 mA DC output current per channel under steady-state conditions, verified across temperature and voltage ranges in the Absolute Maximum Ratings table of its Rev. B datasheet. This drive strength allows direct interfacing with 50 Ω transmission lines or up to 10 standard CMOS loads without external buffering.
Is the ADG3247BRUZ-REEL suitable for automotive applications?
The ADG3247BRUZ-REEL is not AEC-Q100 qualified; however, it operates reliably from −40°C to +85°C and features ±2 kV HBM ESD protection. For automotive body control units requiring extended temperature range, the ADG3247BRUZ-REEL may be used in non-safety-critical subsystems-but AEC-Q100-qualified alternatives should be selected for ASIL-B or higher applications.
How does bus-hold functionality work in the ADG3247BRUZ-REEL?
The ADG3247BRUZ-REEL integrates weak internal pull-up/pull-down networks that retain the last valid logic state on each I/O terminal during high-impedance (tri-state) conditions. This prevents floating inputs during hot-plug events or power sequencing gaps-functionality explicitly documented in the "Features" and "Electrical Characteristics" sections of the ADG3247BRUZ-REEL Rev. B datasheet.
