Product details
Overview
ISL3034EIRUZ-T from Renesas Electronics is a 6-channel bidirectional auto-direction sensing logic level translator operating at up to 100Mbps, supporting VL = +1.35V to +3.2V and VCC = +2.2V to +3.6V. It enables voltage translation between low-voltage microcontrollers (e.g., 1.8V) and higher-voltage peripherals (e.g., 3.3V) without external direction control logic. Its ±15kV IEC61000-4-2 ESD protection on all I/O pins makes it suitable for memory card interfaces and portable USB host systems.
For engineers reviewing the ISL3034EIRUZ-T datasheet, ISL3034EIRUZ-T pinout, ISL3034EIRUZ-T application, or ISL3034EIRUZ-T equivalent, key selection considerations include its auto-direction sensing architecture, 16 Ld UTQFN (2.6mm × 1.8mm) package with thermal pad, guaranteed 100Mbps data rate at VL ≥ 1.62V, shutdown current < 4µA, and compatibility with both push-pull and open-drain drivers.
Technical Context
The ISL3034EIRUZ-T implements a channel-level auto-direction sensing mechanism using high/low threshold detectors, one-shot timers, and large NMOS/PMOS accelerator drivers that actively drive outputs for ~3–4ns before reverting to weak hold mode via internal 30µA pull-up current sources and pass transistors. This architecture eliminates need for direction control pins while enabling bit-by-bit bidirectional translation.
It features dual-supply operation with independent VL and VCC rails, automatic shutdown when VCC falls below VL + 200mV, and ESD-hardened I/O structures meeting ±15kV IEC61000-4-2 air-gap and ±15kV HBM. All I/O pins are referenced to their respective supply (I/OVLx to VL, I/OVCCx to VCC), with VOH tracking VL or VCC and VOL defined relative to GND.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Data Rate | 100Mbps guaranteed at VL ≥ 1.62V - supports high-speed SDIO, eMMC, and SPI interfaces between 1.8V SoCs and 3.3V peripherals. |
| Supply Range (VL) | +1.35V to +3.2V - compatible with 1.5V, 1.8V, and 2.5V logic domains including LPDDR I/O and low-power MCUs. |
| Supply Range (VCC) | +2.2V to +3.6V - supports 2.5V and 3.3V legacy and industrial interface standards. |
| ESD Protection | ±15kV IEC61000-4-2 air-gap on all I/O and EN pins - eliminates need for external TVS diodes in exposed port applications. |
| Shutdown Current | < 4µA VL supply current in SHDN mode - enables ultra-low-power retention in battery-backed systems. |
| Propagation Delay | ≤ 6.5ns (I/OVL → I/OVCC), ≤ 7.5ns (I/OVCC → I/OVL) - ensures timing closure in 100MHz clocked bus interfaces. |
| Channel-to-Channel Skew | ≤ 0.8ns (I/OVL side), ≤ 1.0ns (I/OVCC side) - maintains signal integrity across multi-bit parallel buses like SD data lines. |
Pinout & Package
ISL3034EIRUZ-T is packaged in a 16-lead ultra-thin QFN (UTQFN) measuring 2.6mm × 1.8mm with an exposed thermal pad. The package is RoHS-compliant, uses NiPdAu (e4) termination, and has Moisture Sensitivity Level (MSL) 3 per J-STD-020.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 4, 5, 8, 12, 15 (I/OVL1–I/OVL6) |
VL-side bidirectional I/O | Interface to low-voltage domain (e.g., 1.8V MCU GPIO); auto-senses direction per channel; ±15kV ESD protected. |
| 2, 6, 7, 9, 13, 16 (I/OVCC1–I/OVCC6) |
VCC-side bidirectional I/O | Interface to high-voltage domain (e.g., 3.3V SD card slot); tracks VCC for VOH/VOL; same ESD rating. |
| 3 (VL) | Low-voltage supply rail | Decoupled with 0.1µF capacitor; powers VL-side circuitry and EN input; must be ≤ VCC − 0.2V during operation. |
| 11 (VCC) | High-voltage supply rail | Decoupled with 0.1µF capacitor; powers VCC-side logic and accelerators; enables auto-shutdown if < VL. |
| 10 (GND) | Ground reference | Common return path for both supplies; must connect directly to low-impedance PCB ground plane for ESD robustness. |
| 14 (EN) | Enable control input | Active-high logic input referenced to VL; drives device into tri-state shutdown when low; also triggers auto-shutdown if VL > VCC. |
Key Features
| Feature | Design Value |
|---|---|
| Auto-direction sensing per channel | Eliminates requirement for dedicated GPIO direction control lines and associated firmware overhead in multi-bit interfaces. |
| Integrated 30µA pull-up current sources | Removes need for external pull-ups on open-drain buses (e.g., I²C variants), reducing BOM count and board space. |
| Accelerator-based output drivers | Delivers sub-4ns active drive pulses followed by weak hold, enabling fast edge rates even with high-impedance drivers. |
| Asymmetric shutdown threshold | Triggers automatic low-power state when VCC drops below VL + 200mV - prevents metastability during supply sequencing. |
| Thermal pad with θJC = 44°C/W | Enables efficient heat dissipation in compact portable designs; requires soldered connection to inner ground plane. |
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 |
|---|---|---|---|
| TXS0108E | 8-channel, 3.6V max VCC, no auto-direction sensing - requires external DIR pin control. | Suitable for fixed-direction buses (e.g., UART, SPI) but adds GPIO and firmware complexity for bidirectional protocols. | Choose TXS0108E only when additional channels or TI ecosystem alignment outweighs auto-direction benefit. |
| SN74AVC4T245 | 4-channel, no auto-direction, 3.6V max VCC, lower ESD (±8kV HBM), no integrated pull-ups. | Requires external direction control and pull-up resistors; not recommended for SD/eMMC due to lack of 100Mbps guarantee. | Select SN74AVC4T245 for cost-sensitive, low-pin-count unidirectional applications where ESD robustness is secondary. |
Compared with TXS0108E and SN74AVC4T245, ISL3034EIRUZ-T delivers true per-channel auto-direction sensing, eliminates external components, and provides industry-leading ±15kV IEC61000-4-2 protection - critical for portable memory interfaces where board space and reliability are constrained.

FAQ
What is the maximum data rate supported by the ISL3034EIRUZ-T?
The ISL3034EIRUZ-T guarantees 100Mbps data transfer rate when VL ≥ 1.62V and using push-pull drivers with 150Ω source impedance and ≤15pF load capacitance. At VL = 1.35V, the guaranteed rate drops to 85Mbps. These values are production-tested and specified in the FN6492 Rev.2.00 datasheet under "Electrical Specifications".
Does the ISL3034EIRUZ-T require external pull-up resistors?
No, the ISL3034EIRUZ-T integrates 30µA internal pull-up current sources on all I/O pins during active operation, eliminating the need for external pull-ups in most push-pull or open-drain configurations. External resistors are only recommended for high-speed open-drain signaling with heavy capacitive loads exceeding 35pF.
How does the auto-direction sensing work in the ISL3034EIRUZ-T?
Each channel independently detects voltage transitions on either I/OVLx or I/OVCCx using high/low threshold comparators. A detected transition fires a one-shot that activates large NMOS/PMOS accelerator drivers to rapidly drive the opposite pin, then releases to weak hold mode. This enables true bit-by-bit bidirectional flow without external direction control logic.
What package type is used for the ISL3034EIRUZ-T?
The ISL3034EIRUZ-T uses a 16-lead ultra-thin QFN (UTQFN) package measuring 2.6mm × 1.8mm with an exposed thermal pad. It is RoHS-compliant, features NiPdAu (e4) termination, and is rated MSL-3 per J-STD-020 - identical to the marking "GAE" shown in the ordering table of FN6492 Rev.2.00.
Can the ISL3034EIRUZ-T operate with VL greater than VCC?
Yes - the ISL3034EIRUZ-T tolerates VL > VCC during startup and shutdown without latch-up or damage, though normal operation requires VL ≤ VCC − 0.2V. If VL exceeds VCC by more than 0.7V, the device automatically enters shutdown mode with all I/O pins tri-stated and supply currents reduced to < 4µA.
