Product details
Overview
ADG3304WBRUZ-REEL from Analog Devices is a 4-channel bidirectional logic level translator enabling voltage-domain interoperability between 1.15 V and 5.5 V digital systems. It supports A→Y and Y→A translation without direction control, features <5 µA quiescent current, operates with independent VCCA (1.15–5.5 V) and VCCY (1.65–5.5 V) supplies, and delivers up to 60 Mbps data rate in 2.5 V/3.3 V configurations - used in SPI/MICROWIRE interfaces between low-voltage microcontrollers and higher-voltage peripherals.
For engineers reviewing the ADG3304WBRUZ-REEL datasheet, ADG3304WBRUZ-REEL pinout, ADG3304WBRUZ-REEL application, or ADG3304WBRUZ-REEL equivalent, this page provides verified package mapping (14-lead TSSOP), confirmed bidirectional timing specs (e.g., tP,A→Y = 6–10 ns typ), EN-controlled three-state operation, and automotive-qualified performance across −40°C to +85°C.
Technical Context
The ADG3304WBRUZ-REEL implements a one-shot accelerator architecture per channel, using PMOS/NMOS transistor pairs triggered by edge detection to accelerate rise/fall times. Translation direction is automatically determined by signal activity on either side - no external direction pin required.
VCCA sets logic thresholds for A-side I/Os (A1–A4); VCCY sets thresholds for Y-side I/Os (Y1–Y4). VCCA must be ≤ VCCY for correct operation. The EN pin (referred to VCCA) enables/disables both sides simultaneously into high-impedance state with tEN ≤ 1.8 µs.
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 - supports mixed-supply systems like 1.2 V MCU ↔ 3.3 V sensor or 1.8 V FPGA ↔ 5 V interface IC. |
| Max Data Rate | 60 Mbps (A↔Y) at 2.5 V/3.3 V - sufficient for high-speed SPI Mode 3 (CPOL=1, CPHA=1) and MICROWIRE clock rates up to 30 MHz. |
| Propagation Delay | tP,A→Y = 6–10 ns typ; tP,Y→A = 4–7 ns typ - ensures sub-10 ns latency critical for real-time peripheral handshaking. |
| Quiescent Current | ICCA/ICCY < 5 µA - enables always-on level translation in battery-powered devices without measurable drain. |
| Enable Time | tEN ≤ 1.8 µs - allows rapid power gating of I/O paths during sleep/wake transitions in portable systems. |
| Channel Count | 4 independent bidirectional channels - matches standard SPI bus (SCLK, MOSI, MISO, CS) or dual I²C lines with shared enable control. |
Pinout & Package
ADG3304WBRUZ-REEL is packaged in a 14-lead TSSOP (4.4 mm × 5 mm, 0.65 mm pitch) with exposed paddle (EPAD) tied to GND or left floating - not connected to VCCA/VCCY.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A1–A4 | Bidirectional I/O (VCCA-referenced) | Accept 1.15–5.5 V logic inputs; output VCCA-compatible levels - connect to low-voltage controller side (e.g., ARM Cortex-M0+ GPIO). |
| Y1–Y4 | Bidirectional I/O (VCCY-referenced) | Accept 1.65–5.5 V logic inputs; output VCCY-compatible levels - interface directly to 3.3 V/5 V peripherals (e.g., ADC, EEPROM, transceiver). |
| VCCA | Power supply for A-side | Must be ≤ VCCY; sets VIHA/VILA thresholds - decoupled with 0.1 µF ceramic capacitor near pin. |
| VCCY | Power supply for Y-side | Independent rail; sets VIHY/VILY thresholds - requires separate 0.1 µF decoupling from VCCA. |
| EN | Active-high enable (VCCA-referenced) | Pull high for translation; pull low for simultaneous three-state on all A/Y pins - enables system-level I/O isolation during reset or standby. |
| GND | Analog/digital ground reference | Common return for both supplies; EPAD may be soldered to PCB ground plane for thermal relief. |
Key Features
| Feature | Design Value |
|---|---|
| No direction pin required | Automatic bidirectional edge detection eliminates GPIO overhead and routing complexity in space-constrained layouts. |
| Independent dual-supply operation | VCCA and VCCY rails can be powered from separate regulators - essential for isolating noise-sensitive low-voltage domains from noisy higher-voltage subsystems. |
| Sub-10 ns propagation delay | Enables reliable timing closure in 50 Mbps SPI links with >2 ns setup/hold margin at 3.3 V/1.8 V translation. |
| Automotive qualification | Guaranteed operation from −40°C to +85°C with AEC-Q100 stress testing - suitable for infotainment, telematics, and ADAS sensor hubs. |
| Low input/output capacitance | CA = 9 pF, CY = 6 pF - minimizes signal distortion and loading on high-impedance source drivers (e.g., CMOS outputs driving long traces). |
Applications
| SPI Interface Bridging | Smart Card Reader Interface |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar bidirectional level translation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TXS0104E | 4-channel, 1.2–3.6 V operation; no VCCY rail - uses single supply with internal charge pump; max 60 Mbps but only guaranteed down to 1.65 V VCCA. | Not qualified for automotive; lacks AEC-Q100 rating; limited to lower VCCY range (≤3.6 V). | Select TXS0104E only for cost-sensitive consumer designs where automotive qualification and 5 V compatibility are unnecessary. |
| SN74AVC4T245 | 4-channel, dual-supply (1.2–3.6 V), direction-pin controlled; higher drive strength (24 mA) but requires external DIR signal and has higher ICC (20 µA typical). | Unidirectional per channel unless externally wired for bidirectional use; adds GPIO overhead and layout complexity. | Choose SN74AVC4T245 when precise output drive control is needed and direction logic is already available in system design. |
Compared with TXS0104E and SN74AVC4T245, ADG3304WBRUZ-REEL uniquely combines automotive qualification, true bidirectionality without direction pin, and full 5 V VCCY support - making it the only option for robust, low-pin-count SPI bridging in automotive-grade embedded systems.

FAQ
What is the maximum allowable voltage difference between VCCA and VCCY for reliable operation of the ADG3304WBRUZ-REEL?
The ADG3304WBRUZ-REEL requires VCCA ≤ VCCY, with no minimum difference specified. However, functional operation is guaranteed only when VCCA is within 1.15 V to VCCY and VCCY is within 1.65 V to 5.5 V. For example, VCCA = 1.2 V and VCCY = 1.8 V is valid; VCCA = 3.3 V and VCCY = 3.3 V is also valid. Exceeding VCCA > VCCY risks undefined behavior and is prohibited per Absolute Maximum Ratings.
Can the ADG3304WBRUZ-REEL translate signals between 1.2 V and 5 V logic families?
Yes, the ADG3304WBRUZ-REEL supports A→Y translation from 1.2 V (VCCA) to 5 V (VCCY) and Y→A translation from 5 V to 1.2 V, provided VCCA ≤ VCCY and both supplies remain within their rated ranges (VCCA ≥ 1.15 V, VCCY ≤ 5.5 V). Measured DMAX,A→Y = 25 Mbps and DMAX,Y→A = 25 Mbps under 1.2 V/1.8 V conditions; performance degrades at extreme ratios but remains functional.
Does the ADG3304WBRUZ-REEL require external pull-up or pull-down resistors on A or Y pins?
No, the ADG3304WBRUZ-REEL does not require external biasing resistors on A1–A4 or Y1–Y4 pins. Its internal architecture maintains defined logic states during translation. However, unused channels should have their A or Y pins tied to VCCA or VCCY (respectively) or to GND to prevent floating inputs that could increase leakage or cause oscillation.
Is the ADG3304WBRUZ-REEL pin-compatible with other variants in the ADG330x family?
Yes, ADG3304WBRUZ-REEL (14-lead TSSOP) shares identical pinout with ADG3304BRUZ (same package, non-automotive grade) and ADG3304BRUZ-REEL (tape-and-reel version). All share the same pin configuration shown in Figure 2 of the Rev. E datasheet - including NC pins at positions 6/9 and EPAD connection guidance.
How does the enable (EN) pin affect power consumption in the ADG3304WBRUZ-REEL?
When EN is low, the ADG3304WBRUZ-REEL enters three-state mode: both A-side and Y-side pins go high-impedance, and quiescent currents drop to IHi-Z,A ≤ 5 µA and IHi-Z,Y ≤ 5 µA. When EN is high, ICCA and ICCY rise to ≤5 µA each under static conditions, scaling with data rate and capacitive load - e.g., ICCY reaches ~3 mA at 50 Mbps with 50 pF load.
