Product details
Overview
ADG3304BRUZ from Analog Devices is a 4-channel bidirectional logic level translator enabling voltage-domain interoperability between 1.15 V–5.5 V digital systems. It supports A→Y and Y→A translation without direction control, delivers ≤10 ns propagation delay (typ.), maintains <5 µA quiescent current, and operates across −40°C to +85°C - used in SPI/MICROWIRE interfaces between low-voltage ASICs and higher-voltage peripherals.
For engineers reviewing the ADG3304BRUZ datasheet, ADG3304BRUZ pinout, ADG3304BRUZ application, or ADG3304BRUZ equivalent, key selection criteria include guaranteed bidirectional operation across 1.15 V–5.5 V supply ranges, enable-controlled three-state capability, channel-to-channel skew ≤4 ns, automotive qualification, and TSSOP-14 package compatibility with standard PCB assembly processes.
Technical Context
The ADG3304BRUZ implements a one-shot accelerator architecture per channel, using complementary PMOS/NMOS transistor pairs triggered by edge detection to reduce rise/fall times. Translation direction is determined dynamically by signal source side - no external direction pin required.
VCCA (1.15 V–5.5 V) sets logic thresholds on A-side I/Os (A1–A4); VCCY (1.65 V–5.5 V) sets thresholds on Y-side I/Os (Y1–Y4), with VCCA strictly ≤ VCCY. The EN pin (referred to VCCA) enables three-state operation on both sides simultaneously when low.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Range | VCCA = 1.15 V to 5.5 V; VCCY = 1.65 V to 5.5 V; VCCA ≤ VCCY - enables mixed-voltage system integration without level-shifter sequencing constraints |
| Max Data Rate | 60 Mbps (A↔Y, 2.5 V→3.3 V) - supports high-speed SPI clock domains up to 30 MHz with margin |
| Propagation Delay | 4–10 ns (typ., A↔Y) - ensures timing closure in sub-10 ns critical paths for portable comms interfaces |
| Channel Skew | ≤4 ns (A→Y), ≤3.5 ns (Y→A) - preserves data integrity across parallel bus lines like MICROWIRE data/control |
| Quiescent Current | <5 µA (ICCA + ICCY) - enables always-on level translation in battery-powered GPS/POS systems |
| Enable Time | 1.8 µs max (tEN) - allows rapid power-gating of interface bridges during low-power sleep modes |
| ESD Rating | ±2 kV HBM - meets industrial I/O robustness requirements without external protection |
Pinout & Package
ADG3304BRUZ is packaged in a 14-lead TSSOP (RUZ suffix), with exposed paddle thermally optimized for PCB heat dissipation. Pin 1 is A1; pins 6 and 9 are NC; pin 7 is GND; pin 8 is EN; pin 14 is VCCY.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A1–A4 | Bidirectional I/O (VCCA-referenced) | Accepts or drives 1.15 V–5.5 V logic; auto-detects direction based on active driver side |
| Y1–Y4 | Bidirectional I/O (VCCY-referenced) | Translates A-side signals to VCCY levels and vice versa; supports 1.65 V–5.5 V domain |
| VCCA | Power supply for A-side I/Os | Must be ≤ VCCY; defines VIHA/VILA thresholds and VOHA/VOLA swing on A pins |
| VCCY | Power supply for Y-side I/Os | Defines VIHY/VILY thresholds and VOHY/VOLY swing on Y pins; minimum 1.65 V |
| EN | Active-high enable (VCCA-referenced) | Pulls A/Y pins to high-impedance when low; enables system-level power gating |
| GND | Analog/digital ground reference | Common return for both supplies; must be low-impedance to minimize noise coupling |
Key Features
| Feature | Design Value |
|---|---|
| No direction pin required | Eliminates GPIO overhead and routing complexity in microcontroller-based designs with dynamic bus direction |
| Bidirectional auto-sensing | One-shot accelerator circuit detects edges on either side, enabling seamless A↔Y translation without software coordination |
| Three-state enable control | Single EN pin places all eight I/Os (A1–A4, Y1–Y4) into high-Z simultaneously - simplifies bus arbitration |
| Automotive qualified | Guaranteed operation from −40°C to +85°C with AEC-Q100 stress testing - suitable for infotainment and telematics modules |
| Low capacitance I/Os | CA = 9 pF (A-side), CY = 6 pF (Y-side) - minimizes signal degradation on high-speed traces with >50 pF load budgets |

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, 1.65 V–5.5 V VCCA/VCCB range; requires external pull-up resistors on Y-side; max data rate 60 Mbps | Higher static current (10 µA vs. <5 µA); lacks automotive qualification; no WLCSP option | Select TXS0104E only if board space permits external biasing and automotive compliance is not required. |
| SN74AVC4T245 | Direction-controlled (DIR pin required); 1.2 V–3.6 V VCCA/VCCB; max data rate 380 Mbps; higher drive strength | Requires GPIO for direction management; unsuitable for auto-sensing protocols like SPI full-duplex; not qualified for automotive | Choose SN74AVC4T245 only when directional control is available and ultra-high speed (>100 Mbps) is mandatory. |
Compared with TXS0104E and SN74AVC4T245, ADG3304BRUZ uniquely combines directionless operation, automotive qualification, sub-5 µA quiescent current, and support for 1.15 V minimum VCCA - making it optimal for space-constrained, battery-sensitive, and automotive-grade bidirectional interfaces where GPIO resources are limited.

FAQ
What is the minimum valid VCCA voltage for ADG3304BRUZ operation?
The ADG3304BRUZ supports VCCA down to 1.15 V, as specified in the Absolute Maximum Ratings and confirmed in Table 1 switching characteristics. This enables compatibility with ultra-low-voltage logic families such as 1.2 V ASICs and sub-1.8 V FPGAs. Operation below 1.15 V is not guaranteed and may result in undefined logic thresholds or increased propagation delay.
Can ADG3304BRUZ translate signals from 5 V to 1.2 V?
No - ADG3304BRUZ requires VCCA ≤ VCCY, so 5 V cannot be applied to VCCA. For 5 V → 1.2 V translation, VCCY must be 5 V and VCCA must be 1.2 V. The ADG3304BRUZ then translates Y→A (5 V → 1.2 V) and A→Y (1.2 V → 5 V) bidirectionally. This configuration is fully supported and characterized in the datasheet's Y→A switching tables.
Is ADG3304BRUZ pin-compatible with other Analog Devices level translators?
ADG3304BRUZ is not pin-compatible with ADG3308 or ADG3300 due to differing pin counts (14-pin TSSOP vs. 20-pin LFCSP/16-pin TSSOP) and distinct pin assignments. Its 14-lead TSSOP footprint is unique within the ADG33xx family. Always verify pin mapping against the ADG3304BRUZ-specific Figure 2 before PCB layout.
Does ADG3304BRUZ require external pull-up or pull-down resistors?
No - ADG3304BRUZ contains internal circuitry that eliminates the need for external biasing components on A or Y pins. Unused channels should be tied to their respective supply rail (VCCA or VCCY) or GND per datasheet guidance, but no pull resistors are required for functional operation under normal drive conditions.
What is the thermal performance of ADG3304BRUZ in TSSOP-14 package?
The ADG3304BRUZ in 14-lead TSSOP has a θJA of 89.21°C/W on a 4-layer JEDEC-standard board. With typical ICCA + ICCY < 5 µA at 5.5 V, power dissipation remains below 60 µW - resulting in negligible temperature rise (<0.01°C) under static conditions. Thermal design focus should prioritize GND plane integrity and exposed paddle soldering for transient pulse handling.
