Product details
Overview
ADG3300BRUZ-REEL7 from Analog Devices is an 8-channel bidirectional logic level translator IC designed for voltage-domain bridging between low-voltage (1.15 V–5.5 V) and higher-voltage (1.65 V–5.5 V) digital systems. It operates without direction control pins, supports simultaneous A→Y and Y→A translation on independent channels, delivers up to 60 Mbps data rate (at 2.5 V/3.3 V), and features <1 µA quiescent current - enabling use in battery-powered smart card readers and portable communications interfaces.
For engineers reviewing the ADG3300BRUZ-REEL7 datasheet, ADG3300BRUZ-REEL7 pinout, ADG3300BRUZ-REEL7 application, or ADG3300BRUZ-REEL7 equivalent, key selection criteria include guaranteed bidirectional operation across 1.15 V–5.5 V supply ranges, enable-controlled Y-side three-state capability, channel-to-channel skew ≤4 ns, and TSSOP-20 package compatibility with high-density PCB layouts.
Technical Context
The ADG3300BRUZ-REEL7 implements a one-shot accelerator architecture with PMOS/NMOS transistor pairs per channel, enabling fast edge detection and accelerated charge/discharge of load capacitance. Its dual-supply design requires VCCA ≤ VCCY, with logic levels referenced independently to each rail - A-side signals are VCCA-referenced, Y-side signals are VCCY-referenced.
Enable (EN) is VCCA-referenced and controls Y-side three-state output while pulling A-side pins to GND via 6 kΩ internal resistors when low. No external direction signal is needed, and simultaneous bidirectional data flow across channels is supported - e.g., four channels translating A→Y while others translate Y→A - eliminating timing-critical direction control logic.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Voltage Range | VCCA = 1.15 V to 5.5 V; VCCY = 1.65 V to 5.5 V; VCCA must be ≤ VCCY - defines valid supply pairing for reliable level translation. |
| Max Data Rate | 60 Mbps (A→Y at 2.5 V/3.3 V); 50 Mbps typical across most VCCA/VCCY combinations - supports high-speed serial buses like I²C, SPI, and UART. |
| Propagation Delay | tP,A-Y = 6–12 ns (typ); tP,Y-A = 4–14 ns (typ) - enables sub-10 ns timing margins in 50+ Mbps interfaces. |
| Channel Skew | tSKEW,A-Y ≤ 4 ns; tSKEW,Y-A ≤ 6.5 ns - ensures deterministic parallel bus timing across all 8 channels. |
| Quiescent Current | ICCA/ICCY ≤ 5 µA (max); <1 µA typical - critical for always-on, ultra-low-power IoT sensor nodes and mobile accessories. |
| Enable Function | EN pin places Y1–Y8 in high-impedance state while pulling A1–A8 to GND via 6 kΩ resistors - enables bus sharing and hot-swap isolation. |
| Operating Temp | −40°C to +85°C - qualified for industrial and extended-temperature embedded applications including telecom and storage systems. |
Pinout & Package
The ADG3300BRUZ-REEL7 is housed in a 20-lead TSSOP package (4.4 mm × 6.5 mm, 0.65 mm pitch) with exposed pad for thermal performance. Pin numbering follows standard top-view orientation with Pin 1 at top-left corner.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A1–A8 | Bidirectional I/O (VCCA-referenced) | Connect to low-voltage domain (e.g., 1.2 V/1.8 V microcontroller); auto-detects direction based on signal edge. |
| Y1–Y8 | Bidirectional I/O (VCCY-referenced) | Connect to high-voltage domain (e.g., 3.3 V/5 V peripheral); enters Hi-Z when EN = 0. |
| VCCA | Low-side power supply | Must be ≤ VCCY; powers A-side circuitry and sets A-side logic thresholds (VIHA = VCCA − 0.4 V). |
| VCCY | High-side power supply | Supplies Y-side; sets Y-side thresholds (VOHY = VCCY − 0.4 V); must power up before VCCA. |
| EN | Active-high enable input | VCCA-referenced; drives Y-side into three-state and pulls A-side to GND via 6 kΩ when low. |
| GND | Digital ground reference | Common return for both domains; decoupling caps required at VCCA and VCCY pins. |
Key Features
| Feature | Design Value |
|---|---|
| No direction pin required | Eliminates external control logic and timing constraints - simplifies PCB routing and firmware design for bidirectional buses. |
| Independent dual-supply operation | VCCA and VCCY can be set to different voltages within spec (e.g., 1.8 V ↔ 3.3 V), enabling interoperability across mixed-voltage SoC subsystems. |
| Three-state Y-side enable | EN pin allows dynamic bus arbitration - essential for shared data paths in multi-peripheral systems like POS terminals and network switches. |
| Low propagation skew | ≤4 ns channel-to-channel skew (A→Y) ensures tight timing alignment across 8-bit parallel interfaces such as memory-mapped peripherals. |
| Ultra-low quiescent current | <1 µA ICCA/ICCY in active mode - extends battery life in portable devices without sacrificing speed or functionality. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar bidirectional level translation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TXB0108PWR | Auto-direction sensing with integrated 5-kΩ pull-ups on both sides; no enable pin; max 100 Mbps but requires ≥1.65 V on both rails. | Not suitable for asymmetric enable control or scenarios requiring Y-side Hi-Z isolation. | Prefer ADG3300BRUZ-REEL7 when EN-driven bus arbitration or strict VCCA ≤ VCCY sequencing is required. |
| SN74AVC8T245RHLR | Direction-pin controlled (DIR); unidirectional per channel group; 3.6 V max VCC; higher ICC (20 µA typ). | Requires external direction logic and cannot support simultaneous bidirectional flow on same bus. | Choose ADG3300BRUZ-REEL7 for true bidirectional, pin-count-constrained designs where DIR signal routing is impractical. |
Compared with TXB0108PWR and SN74AVC8T245RHLR, ADG3300BRUZ-REEL7 uniquely combines VCCA-referenced enable control, guaranteed operation down to 1.15 V on A-side, and hardware-enforced VCCA ≤ VCCY compliance - making it optimal for ultra-low-voltage IoT edge nodes and legacy system upgrades.

FAQ
What is the minimum VCCA voltage supported by the ADG3300BRUZ-REEL7?
The ADG3300BRUZ-REEL7 supports VCCA as low as 1.15 V, enabling direct interfacing with advanced ultra-low-voltage logic families such as 1.2 V I/O standards. Operation below 1.15 V is not guaranteed and may result in undefined logic thresholds or increased propagation delay. The device remains fully functional across the entire 1.15 V to 5.5 V VCCA range when paired with a compliant VCCY supply.
Can the ADG3300BRUZ-REEL7 translate between 5 V and 1.8 V domains?
Yes, the ADG3300BRUZ-REEL7 supports 5 V ↔ 1.8 V translation, with VCCY = 5 V and VCCA = 1.8 V. In this configuration, A-side inputs accept 1.8 V logic levels and produce 5 V-compatible outputs at Y pins, while Y-side inputs accept 5 V logic and produce 1.8 V-compatible outputs at A pins. Maximum data rate is 50 Mbps under these conditions with CL = 15 pF (Y→A) or 50 pF (A→Y).
Does the ADG3300BRUZ-REEL7 require external pull-up resistors?
No, the ADG3300BRUZ-REEL7 does not require external pull-up resistors for normal bidirectional operation. Its internal architecture uses active transistor switching rather than passive pull-ups. However, unused A or Y pins should be tied to their respective VCC rail (VCCA or VCCY) or GND to prevent floating inputs and ensure predictable leakage behavior per the datasheet layout guidelines.
How does the enable (EN) pin affect power consumption in the ADG3300BRUZ-REEL7?
When EN = 0, the ADG3300BRUZ-REEL7 enters three-state mode: Y1–Y8 go high-impedance and A1–A8 are pulled to GND via internal 6 kΩ resistors. This reduces ICCA and ICCY to ≤5 µA each - a >90% reduction versus active mode (typical <1 µA). This feature is critical for extending battery life in always-connected portable devices using the ADG3300BRUZ-REEL7.
Is the ADG3300BRUZ-REEL7 compatible with I²C bus protocols?
Yes, the ADG3300BRUZ-REEL7 supports I²C-level translation in both directions (A↔Y) without external components, provided VCCA and VCCY are set to valid I²C domain voltages (e.g., 1.8 V ↔ 3.3 V). Its bidirectional architecture, low capacitance (6 pF on Y pins), and sub-10 ns propagation delay meet standard-mode (100 kHz) and fast-mode (400 kHz) timing requirements - though slew-rate limiting may be needed for high-speed mode (3.4 MHz) compliance.
