Product details
Overview
PI4ULS3V304AQ1ZMAEX from Diodes Incorporated is an automotive-qualified 4-bit bidirectional level translator IC for push-pull logic interfaces, supporting independent dual-supply operation (0.9–2.0 V on A port, 1.65–3.6 V on B port), 140 Mb/s data rate, 100 pF capacitive drive, and AEC-Q100 Grade 1 qualification (−40 °C to +125 °C). It enables voltage translation between low-voltage microcontrollers and higher-voltage peripherals in automotive infotainment and ADAS sensor interfaces.
For engineers reviewing the PI4ULS3V304AQ1ZMAEX datasheet, PI4ULS3V304AQ1ZMAEX pinout, PI4ULS3V304AQ1ZMAEX application, or PI4ULS3V304AQ1ZMAEX equivalent, this device delivers autosensing bidirectional translation without direction control pins, overvoltage-tolerant I/Os, non-preferential power-up sequencing, and 3-state enable control - critical for robust mixed-voltage automotive subsystem design.
Technical Context
The PI4ULS3V304AQ1ZMAEX implements a dual-rail autosensing architecture with independent A- and B-port supply domains (VCCA and VCCB), enabling translation regardless of relative rail voltage magnitude. Each of its four bidirectional channels uses one-shot edge-detection circuitry to auto-determine signal direction and accelerate output transitions.
It features overvoltage-tolerant EN and I/O pins referenced to VCCA, supports power-off protection with high-impedance I/O states when either supply is absent, and achieves ≤0.15 ns channel-to-channel skew at 15 pF load - ensuring timing integrity across all four channels in high-speed serial links like SPI and I²C derivatives.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Range (A port) | 0.9 V to 2.0 V - supports ultra-low-voltage logic (e.g., 1.2 V/1.8 V MCUs) while maintaining full functionality |
| Supply Range (B port) | 1.65 V to 3.6 V - interfaces directly with 1.8 V, 2.5 V, 3.3 V peripherals without external level-shifting components |
| Max Data Rate | 140 Mb/s - validated at 2.25–3.6 V VCCB and 1.65–2.0 V VCCA with 15 pF load, enabling high-speed sensor or display interface use |
| Capacitive Drive | 100 pF - drives EMI filters and long PCB traces common in automotive cabin modules without signal degradation |
| Operating Temp | −40 °C to +125 °C ambient - meets AEC-Q100 Grade 1 requirements for under-hood and dashboard electronics |
| ESD Rating | 2 kV system-level HBM - provides robustness against electrostatic discharge in assembly and field environments |
| Enable Function | Active-high EN referenced to VCCA - places all I/Os in 3-state to reduce quiescent current to ≤6 µA (VCCA) / ≤6 µA (VCCB) |
Pinout & Package
Supplied in a 12-pin UQFN package (ZMA footprint, 2.0 mm × 1.6 mm, 0.4 mm pitch) with wettable flanks for automated optical inspection. Thermal pad exposed on bottom for enhanced heat dissipation in compact automotive modules.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | VccA | A-port supply rail (0.9–2.0 V); powers internal A-side logic and I/O buffers |
| 2–5 | A1–A4 | Bidirectional I/Os referenced to VccA; auto-sense direction per channel without control lines |
| 6 | GND | Common ground reference for both supply domains and signal integrity |
| 7–10 | B4–B1 | Bidirectional I/Os referenced to VccB; electrically isolated from A-side but logically paired with A1–A4 |
| 11 | VccB | B-port supply rail (1.65–3.6 V); powers B-side logic and high-drive output stages |
| 12 | EN | Active-high enable input referenced to VccA; asserts 3-state on all I/Os when low, reducing total supply current |
Key Features
| Feature | Design Value |
|---|---|
| Autosensing bidirectional translation | Eliminates need for direction-control signals and simplifies PCB routing in SPI, UART, and GPIO expansion applications |
| Non-preferential power-up sequencing | Allows VCCA and VCCB to power up in any order without latch-up or damage - critical for modular automotive ECUs |
| Overvoltage-tolerant I/O and EN pins | Withstands up to 2.6 V (A-side) and 4.0 V (B-side) inputs even when respective supplies are off - enhances system resilience |
| Power-off protection | I/Os enter high-impedance state if either VCCA or VCCB = 0 V - prevents back-powering and signal contention |
| Low bit-to-bit skew | ≤0.15 ns max skew across all four channels at 15 pF ensures deterministic timing in parallel data paths |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar bidirectional level translation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NXP PCA9306DCUR | 2-channel, max 100 Mb/s, VREF-based architecture requiring external reference; no AEC-Q100 qualification | Limited to industrial/commercial temp range (−40 °C to +85 °C); lacks automotive change control and PPAP support | Use only where AEC-Q100 is not required and channel count is ≤2; lower cost but higher design overhead due to VREF dependency |
| Texas Instruments TXS0104EPRJR | 4-channel, 60 Mb/s max, auto-bidirectional with 3.6 V max VCCB; AEC-Q100 Grade 2 (−40 °C to +105 °C), not Grade 1 | Insufficient for under-hood applications requiring full −40 °C to +125 °C operation; lower speed limits use in high-bandwidth camera links | Select when Grade 2 qualification suffices and data rates ≤60 Mb/s; avoid for ADAS or infotainment display timing-critical paths |
Compared with PCA9306DCUR and TXS0104EPRJR, the PI4ULS3V304AQ1ZMAEX uniquely combines AEC-Q100 Grade 1, 140 Mb/s performance, true dual-supply independence (no VREF), and 4-channel integration - making it the only drop-in solution for automotive-grade high-speed mixed-voltage interconnects demanding full temperature coverage and production traceability.

FAQ
Is PI4ULS3V304AQ1ZMAEX pin-compatible with PI4ULS3V304AQ?
Yes - the "1ZMAEX" suffix denotes tape-and-reel packaging (X) and Pb-free/Green compliance (E), with identical UQFN-12 (ZMA) footprint, pinout, and electrical behavior as the base PI4ULS3V304AQ. No layout or schematic changes are needed when upgrading to the automotive-qualified variant.
Can VCCA be higher than VCCB in PI4ULS3V304AQ1ZMAEX?
Yes - the device explicitly supports VCCA > VCCB (e.g., 1.8 V on A port, 1.65 V on B port), unlike many competitive translators that require VCCA ≤ VCCB − 0.4 V. This flexibility enables use cases such as translating from a 1.8 V MCU to a 1.65 V memory interface or low-power sensor.
What is the maximum capacitive load supported at 140 Mb/s?
The 140 Mb/s rating is guaranteed with ≤15 pF load per I/O, as specified in the timing table for VCCB = 2.25–3.6 V and VCCA = 1.65–2.0 V. At 100 pF, the maximum data rate drops to 60 Mb/s - confirmed by the MIDR specification table. For 100 pF loads, derate speed accordingly or add series termination.
Does the EN pin require a pull-up resistor?
No - the EN pin is internally biased and functions as a standard CMOS input referenced to VCCA. A pull-down is recommended only if default-disabled operation is required at power-up; otherwise, tie EN directly to VCCA for always-enabled operation. No external pull-up is necessary or specified in the datasheet.
