Product details
Overview
ADG3304BCPZ-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 pins, delivers ≤10 ns propagation delay (at 3.3 V/5 V), maintains <5 µA quiescent current, and operates across −40°C to +85°C - deployed in SPI/MICROWIRE interfaces between low-voltage ASICs and higher-voltage peripherals.
For engineers reviewing the ADG3304BCPZ-REEL datasheet, ADG3304BCPZ-REEL pinout, ADG3304BCPZ-REEL application, or ADG3304BCPZ-REEL equivalent, key selection criteria include guaranteed bidirectional operation across 1.15–5.5 V dual-supply ranges, channel-to-channel skew ≤4 ns, enable-controlled three-state capability, and automotive qualification per AEC-Q100.
Technical Context
The ADG3304BCPZ-REEL implements a one-shot accelerator architecture with PMOS/NMOS transistor pairs per channel, enabling edge-triggered fast charge/discharge of capacitive loads. Its dual-rail design requires VCCA ≤ VCCY, with independent logic thresholds defined per supply (e.g., VIHA = VCCA × 0.72 at 1.8 V, VIHY = VCCY × 0.67 at 1.8 V).
Enable (EN) is referenced to VCCA and asserts high-impedance on both A and Y sides when low. No external direction signal is needed: translation direction is determined dynamically by which side drives first, supported by internal inverters (U1–U4) and a one-shot generator that pulses transistors T1–T4 on signal edges.
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 - enables interoperability between sub-1.2 V logic and 5 V legacy systems. |
| Max Data Rate | 60 Mbps (A→Y/Y→A, 2.5 V→3.3 V) - supports high-speed SPI clocking up to 30 MHz with margin. |
| Propagation Delay | tP,A→Y = 6–10 ns (typ), tP,Y→A = 4–7 ns (typ) - ensures timing-critical bidirectional protocols meet setup/hold budgets. |
| Quiescent Current | ICCA/ICCY ≤ 5 µA (max) - minimizes power in always-on battery-powered interfaces like smart card readers. |
| Channel Skew | tSKEW,A→Y ≤ 4 ns, tSKEW,Y→A ≤ 3.5 ns - preserves data integrity across parallel bus lines (e.g., 4-bit SPI data + clock). |
| Enable Time | tEN ≤ 1.8 µs - allows rapid bus arbitration and dynamic isolation in multi-master systems. |
| ESD Rating | ±2 kV HBM - meets IEC 61000-4-2 Level 2 for robustness in handheld device interconnects. |
Pinout & Package
ADG3304BCPZ-REEL is packaged in a 14-lead TSSOP (4.4 mm × 5 mm, 0.65 mm pitch) with exposed paddle thermally connected to GND. Pin 1 is A1; pins 6 and 9 are no-connect; EN is active-high and VCCA-referenced.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A1–A4 | Bidirectional I/O (A-side) | Interface with low-voltage domain (VCCA); tolerate −0.3 V to VCCA + 0.3 V; capacitance = 9 pF. |
| Y1–Y4 | Bidirectional I/O (Y-side) | Interface with high-voltage domain (VCCY); tolerate −0.3 V to VCCY + 0.3 V; capacitance = 6 pF. |
| VCCA | Power Supply (A-side) | Defines logic thresholds for A pins; must be ≤ VCCY; supplies ICCA ≤ 5 µA in active mode. |
| VCCY | Power Supply (Y-side) | Defines logic thresholds for Y pins; minimum 1.65 V; supplies ICCY ≤ 5 µA in active mode. |
| EN | Enable Input | Active-high, VCCA-referenced; pulls A/Y pins to high-Z when low; leakage ±1 µA; capacitance 3 pF. |
| GND | Ground Reference | Common return for both domains; exposed paddle must connect to GND or float - never to VCCA/VCCY. |
Key Features
| Feature | Design Value |
|---|---|
| No direction pin required | Eliminates PCB routing complexity and firmware overhead for bidirectional buses like SPI half-duplex or I²C-like protocols. |
| Guaranteed operation down to 1.15 V VCCA | Supports next-generation ultra-low-power microcontrollers and IoT sensors operating below 1.2 V. |
| Three-state enable on both sides | Allows safe bus sharing among multiple translators or peripherals without contention during reset or sleep modes. |
| Automotive qualified (AEC-Q100) | Validated for operation from −40°C to +85°C with robust ESD and latch-up immunity - suitable for infotainment and telematics modules. |
| Low input/output capacitance | A-side CA = 9 pF, Y-side CY = 6 pF - reduces loading on high-speed drivers and improves signal integrity at >25 Mbps. |

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, 1.65–5.5 V operation; no VCCA ≤ VCCY constraint; higher ICCQ (10 µA typ); 14-pin VSSOP only. | Supports VCCA > VCCY configurations; lacks automotive qualification; lower max data rate (48 Mbps). | Select for designs requiring flexible rail ordering or TI ecosystem compatibility; avoid where AEC-Q100 compliance is mandatory. |
| SN74AVC4T245 | 4-channel, 1.2–3.6 V; direction pin required; higher drive strength (24 mA); 16-pin SOIC/TSSOP. | Requires firmware-controlled DIR signal; unsuitable for true bidirectional protocols like I²C; not qualified for automotive temp range. | Choose when high-current driving (>12 mA) is needed or when direction control is already implemented in system logic. |
Compared with TXS0104E and SN74AVC4T245, ADG3304BCPZ-REEL uniquely combines automotive qualification, strict VCCA ≤ VCCY guarantee for predictable threshold behavior, and sub-5 µA quiescent current - making it optimal for safety-critical, battery-sensitive, and timing-strict embedded interfaces.

FAQ
What supply voltage constraints apply to ADG3304BCPZ-REEL?
ADG3304BCPZ-REEL requires VCCA ≤ VCCY, with VCCA ranging from 1.15 V to 5.5 V and VCCY from 1.65 V to 5.5 V. Violating VCCA ≤ VCCY risks undefined logic thresholds and potential damage. The ADG3304BCPZ-REEL datasheet specifies absolute maximum ratings: VCCA to GND = −0.3 V to +7 V, VCCY to GND = VCCA to +7 V.
Does ADG3304BCPZ-REEL require external pull-up resistors?
No, ADG3304BCPZ-REEL does not require external pull-up resistors for normal bidirectional operation. Its internal architecture actively drives both high and low states on A and Y sides. Pull-ups may be needed only if unused channels are left floating - in which case A or Y pins should be tied to their respective VCC rail or GND per the ADG3304BCPZ-REEL datasheet guidelines.
How does the enable (EN) pin function on ADG3304BCPZ-REEL?
The EN pin on ADG3304BCPZ-REEL is active-high and referenced to VCCA. When EN is low, all A1–A4 and Y1–Y4 pins enter high-impedance state. When EN is high, bidirectional translation operates normally. Leakage current on EN is ±1 µA, and its input thresholds scale with VCCA (e.g., VIHEN = VCCA × 0.72 at 1.8 V). The ADG3304BCPZ-REEL enable time tEN is ≤1.8 µs.
Is ADG3304BCPZ-REEL suitable for I²C bus level translation?
ADG3304BCPZ-REEL is not recommended for standard I²C bus translation because I²C requires open-drain operation with bidirectional wired-AND signaling and specific rise-time control via pull-up resistors. The ADG3304BCPZ-REEL drives push-pull outputs and lacks built-in slew-rate control for I²C-compliant waveforms. For I²C, dedicated translators like the PCA9306 are preferred.
What package variants are available for ADG3304BCPZ-REEL?
ADG3304BCPZ-REEL is specified in the 14-lead TSSOP package (CPZ suffix), with body dimensions 4.4 mm × 5.0 mm and 0.65 mm lead pitch. Other ADG3304 variants include 12-ball WLCSP and 20-lead LFCSP, but ADG3304BCPZ-REEL exclusively uses the TSSOP package per Analog Devices' ordering guide Rev. E.
