Product details
Overview
ADG3300BRUZ-REEL from Analog Devices is an 8-channel bidirectional logic level translator IC operating from 1.15 V to 5.5 V supply range, enabling voltage translation between mismatched digital domains (e.g., 1.2 V ↔ 1.8 V, 1.8 V ↔ 3.3 V, 3.3 V ↔ 5 V). It features no direction pin, <1 µA quiescent current, and guaranteed operation across −40°C to +85°C. It is used in multivoltage data buses between low-voltage microcontrollers and higher-voltage peripherals.
For engineers reviewing the ADG3300BRUZ-REEL datasheet, ADG3300BRUZ-REEL pinout, ADG3300BRUZ-REEL application, or ADG3300BRUZ-REEL equivalent, key selection criteria include bidirectional A↔Y channel architecture, VCCA < VCCY supply constraint, EN-controlled Y-side three-state, propagation delay ≤10 ns (typ.) at 3.3 V/5 V, and TSSOP-20 package compatibility with high-density PCB layouts.
Technical Context
The ADG3300BRUZ-REEL implements a one-shot accelerator architecture per channel, using complementary PMOS/NMOS transistor pairs (T1–T4) triggered by edge detection to achieve fast rise/fall times. Translation occurs without external direction control: signals applied to A-side pins (VCCA-referenced) appear as VCCY-compatible levels on Y-side pins, and vice versa.
Operation requires VCCA ≤ VCCY, with VCCA setting A-side logic thresholds and VCCY setting Y-side thresholds. The EN pin-referenced to VCCA-enables three-state output on Y1–Y8 while pulling A1–A8 to GND via internal 6 kΩ resistors. Power supplies must be decoupled locally with 0.1 µF capacitors.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Channels | 8 independent bidirectional A↔Y channels; supports simultaneous mixed-direction data flow (e.g., 4 A→Y + 4 Y→A). |
| Supply Range | VCCA = 1.15 V to 5.5 V; VCCY = 1.65 V to 5.5 V; VCCA must be ≤ VCCY for reliable operation. |
| Max Data Rate | 60 Mbps (A→Y) at VCCA = 2.5 V / VCCY = 3.3 V; 50 Mbps typical across most common combinations (e.g., 1.8 V ↔ 3.3 V, 3.3 V ↔ 5 V). |
| Propagation Delay | tP,A-Y = 6–10 ns (typ.), tP,Y-A = 4–7 ns (typ.) under 50 Ω / 50 pF (A→Y) or 15 pF (Y→A) load conditions. |
| Quiescent Current | ICCA = 0.17–5 µA, ICCY = 0.27–5 µA (VCCA = VCCY = 5.5 V); <1 µA total in active mode enables battery-sensitive designs. |
| Enable Function | EN pin (VCCA-referenced) places Y1–Y8 in high-impedance state while pulling A1–A8 to GND via 6 kΩ resistors-no external pull-downs required. |
Pinout & Package
ADG3300BRUZ-REEL is housed in a 20-lead TSSOP package (4.4 mm × 6.5 mm, 0.65 mm pitch), optimized for automated assembly and thermal performance (θJA = 78°C/W on 4-layer board).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A1–A8 | Bidirectional I/O (VCCA-referenced) | Connect to lower-voltage domain (e.g., 1.2 V/1.8 V MCU I/O); tolerate −0.3 V to (VCCA + 0.3 V). |
| Y1–Y8 | Bidirectional I/O (VCCY-referenced) | Connect to higher-voltage domain (e.g., 3.3 V/5 V peripheral bus); tolerate −0.3 V to (VCCY + 0.3 V). |
| VCCA | Power supply for A-side logic | Must be ≤ VCCY; sets VIHA/VILA thresholds; requires local 0.1 µF decoupling to GND. |
| VCCY | Power supply for Y-side logic | Must be ≥ VCCA; sets VIHY/VILY thresholds; requires local 0.1 µF decoupling to GND. |
| EN | Active-high enable input | Referenced to VCCA; drives Y-side into Hi-Z and activates A-side 6 kΩ pull-downs when low. |
| GND | Digital ground reference | Common return for both supply domains; must be low-impedance and star-connected. |
Key Features
| Feature | Design Value |
|---|---|
| No direction pin required | Eliminates timing-critical direction-control signals and simplifies PCB routing in full-duplex bus interfaces. |
| Bidirectional per-channel architecture | Enables concurrent A→Y and Y→A translation on separate channels-no shared direction bus needed. |
| One-shot accelerator circuitry | Reduces rise/fall times to 1–3.5 ns (typ.) by transiently overdriving output transistors during edge transitions. |
| Low-leakage three-state mode | EN = 0 reduces ICCA/Iccy to ≤5 µA each while isolating Y-bus-critical for shared-data-bus arbitration. |
| Voltage-flexible supply support | Validated across 1.15 V–5.5 V range with guaranteed specs at 1.2/1.8/2.5/3.3/5 V combinations-no requalification needed for voltage scaling. |
Applications
| Smart Card Interface | Mobile Baseband-to-Application Processor Bus |

Equivalent & Alternatives
The following parts are listed as comparable options for similar bidirectional level translation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TXS0108E | 8-channel, auto-direction sensing; supports VCCA = 1.2–3.6 V, VCCB = 1.65–5.5 V; no EN pin; higher ICC (≈10 µA). | Lacks hardware EN control-relies on bus activity for direction detection; unsuitable where deterministic three-state is required. | Select TXS0108E only if direction ambiguity is acceptable and EN functionality is unnecessary. |
| SN74AVC8T245 | 8-bit dual-supply translator with direction pin (DIR); VCCA = 1.2–3.6 V, VCCB = 1.2–3.6 V; supports DIR-controlled unidirectional flow. | Requires external direction control signal and cannot perform true simultaneous bidirectional translation on same channel. | Choose SN74AVC8T245 when strict unidirectional control per channel is preferred and direction timing can be managed externally. |
Compared with TXS0108E and SN74AVC8T245, ADG3300BRUZ-REEL uniquely combines hardware-enforced three-state isolation, no-direction-pin bidirectionality, and sub-1 µA quiescent current-making it optimal for power-constrained, bus-arbitrated systems requiring deterministic control.

FAQ
What is the minimum valid VCCA voltage for ADG3300BRUZ-REEL operation?
The ADG3300BRUZ-REEL is fully specified down to VCCA = 1.15 V, with guaranteed VIHA = VCCA − 0.3 V and VIHEN = VCCA − 0.3 V at this rail. Operation below 1.15 V is not characterized and may result in undefined logic thresholds or increased propagation delay. Always maintain VCCA ≤ VCCY for functional reliability.
Can ADG3300BRUZ-REEL translate between 5 V and 1.2 V logic domains?
No-ADG3300BRUZ-REEL requires VCCA ≤ VCCY, and its absolute maximum ratings limit VCCA to ≤ VCCY and VCCY to ≤ (VCCA + 7 V). While 1.2 V → 5 V translation is supported (VCCA = 1.2 V, VCCY = 5 V), the reverse (5 V → 1.2 V) violates the VCCA ≤ VCCY constraint and exceeds input voltage tolerance on A-side pins (max −0.3 V to VCCA + 0.3 V = 1.5 V).
Does ADG3300BRUZ-REEL require external pull-up or pull-down resistors on A or Y pins?
No-ADG3300BRUZ-REEL integrates 6 kΩ pull-down resistors on A1–A8 when EN = 0. During normal operation (EN = 1), no external biasing is required. Pull-ups on Y pins are unnecessary unless system-level bus-hold or open-drain emulation is needed; the device drives actively in both directions.
What is the maximum capacitive load ADG3300BRUZ-REEL can drive while maintaining 50 Mbps data rate?
For A→Y translation at 50 Mbps, ADG3300BRUZ-REEL is characterized up to 50 pF load capacitance (e.g., Figure 33). For Y→A translation at 50 Mbps, max load is 15 pF (e.g., Figure 34). Exceeding these values increases propagation delay and jitter-designers should verify eye diagram integrity (Figures 21–26) for their specific CL and data pattern.
How does the EN pin behave during power-up sequencing?
The EN pin is referenced to VCCA and must be held low until both VCCA and VCCY reach stable nominal voltages. Premature EN assertion before VCCY stabilizes risks excessive current draw due to internal FET conduction paths. Recommended sequence: apply VCCY first, then VCCA, then drive EN high after both supplies settle (>100 µs typical).
