Product details
Overview
ISL3034EIRTZ-T from Renesas Electronics is a 6-channel bidirectional auto-direction sensing logic level translator operating from VL = +1.35V to +3.2V and VCC = +2.2V to +3.6V, delivering 100Mbps data rate with ±15kV IEC61000-4-2 ESD protection on all I/O pins, and integrated 30µA pull-up current sources per channel - used in voltage-domain bridging between 1.8V microcontrollers and 3.3V peripherals.
For engineers reviewing the ISL3034EIRTZ-T datasheet, ISL3034EIRTZ-T pinout, ISL3034EIRTZ-T application, or ISL3034EIRTZ-T equivalent, key selection criteria include bidirectional auto-sensing capability, shutdown mode activation via EN or VCC/VL under-voltage condition, 16-lead TQFN (3mm×3mm) package compatibility, and guaranteed 100Mbps operation at VL ≥ 1.62V with push-pull drivers.
Technical Context
The ISL3034EIRTZ-T implements per-channel accelerator circuitry with high/low threshold detectors, one-shot timers, and large NMOS/PMOS output drivers that actively drive opposite-side I/O pins for ≤4ns before reverting to weak hold mode using internal current sources or pass transistors. This architecture enables bit-by-bit direction detection without external control logic.
Each channel operates independently: an I/OVL transition triggers up-level translation to I/OVCC (tracking VCC), while an I/OVCC transition triggers down-level translation to I/OVL (tracking VL); EN input controls global enable/shutdown, and automatic shutdown activates when VCC falls below VL by >0.7V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Data Rate | 100Mbps at VL ≥ 1.62V with push-pull drivers - supports high-speed SPI, I²C, and GPIO bridging between low- and mid-voltage domains. |
| Supply Range (VL) | +1.35V to +3.2V - compatible with 1.5V, 1.8V, and 2.5V logic families on the low-voltage side. |
| Supply Range (VCC) | +2.2V to +3.6V - interfaces directly with 2.5V and 3.3V systems without external regulators. |
| ESD Protection | ±15kV IEC61000-4-2 air-gap discharge on all I/O and EN pins - eliminates need for external TVS diodes in memory card or USB port interfaces. |
| Shutdown Current | <2.5µA ICCSD and <4µA ILSD - enables ultra-low-power retention in battery-backed systems during sleep states. |
| Propagation Delay | ≤6.5ns tPDVL and ≤7.5ns tPDVCC - ensures timing-critical signal integrity in synchronous interfaces like SDIO or eMMC. |
| Channel-to-Channel Skew | ≤0.8ns tSKEWL and ≤1.0ns tSKEWC - maintains parallel bus coherence across all six channels. |
Pinout & Package
ISL3034EIRTZ-T is packaged in a 16-lead TQFN (3mm × 3mm, 0.5mm pitch) with exposed thermal pad, RoHS-compliant matte tin (e3) termination, and moisture sensitivity level (MSL) 3 per JEDEC J-STD-020.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 4, 5, 8, 12, 15 | I/OVLx (x=1–6) | Bidirectional I/O referenced to VL supply; auto-senses direction per transition; ±15kV ESD protected. |
| 2, 6, 7, 9, 13, 16 | I/OVCCx (x=1–6) | Bidirectional I/O referenced to VCC supply; tracks VCC for VOH/VOL; ±15kV ESD protected. |
| 3 | VL | Low-voltage logic supply input (1.35V–3.2V); requires 0.1µF decoupling to GND. |
| 10 | VCC | High-voltage logic supply input (2.2V–3.6V); requires 0.1µF decoupling to GND. |
| 11 | GND | Ground reference for both supply domains and ESD return path; must connect to low-impedance PCB plane. |
| 14 | EN | Active-high enable input; logic low forces tri-state shutdown; internally referenced to VL; ±15kV ESD protected. |
Key Features
| Feature | Design Value |
|---|---|
| Auto-direction sensing per channel | Eliminates dedicated DIR pins and GPIO overhead - each I/O pair detects direction dynamically on signal edge, enabling software-transparent multi-voltage interconnects. |
| Integrated 30µA pull-up current sources | Removes need for external pull-ups on open-drain buses (e.g., I²C), reducing BOM count and board space while maintaining rise-time compliance up to 100Mbps. |
| Accelerator-based output drivers | Delivers sub-4ns active drive pulses followed by weak hold - achieves fast edge rates even with high-capacitance loads (>35pF) and mitigates slow-transition issues from weak drivers. |
| Automatic VCC/VL under-voltage shutdown | Tri-states all I/Os and reduces supply current to <4µA when VCC drops below VL + 0.7V - prevents undefined logic states during power sequencing or brown-out events. |
| Full I/O ESD robustness | ±15kV IEC61000-4-2 on every I/OVL/I/OVCC/EN pin - enables direct connection to exposed ports (e.g., SD card slots) without board-level protection components. |

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 control; lower ESD rating (±8kV HBM only). | Suitable for fixed-direction parallel buses (e.g., address/data multiplexing), not dynamic bidirectional protocols like SDIO. | Choose TXS0108E only if direction is static and higher channel count justifies added GPIO and layout complexity. |
| SN74AVC8T245 | 8-channel, 3.6V max VCC, direction-controlled (DIR pin), no integrated pull-ups, no auto-sensing, ±5kV HBM ESD. | Requires external 10kΩ pull-ups and precise DIR timing coordination; limited to lower-speed (<40Mbps) applications due to slower propagation. | Select SN74AVC8T245 for cost-sensitive, non-ESD-critical industrial control where manual direction management is acceptable. |
Compared with TXS0108E and SN74AVC8T245, the ISL3034EIRTZ-T delivers true bit-level auto-direction sensing, eliminates external pull-up resistors, and provides industry-leading ±15kV IEC61000-4-2 protection - making it optimal for compact, high-reliability, mixed-voltage embedded interfaces where GPIO count and board space are constrained.

FAQ
What is the maximum data rate supported by the ISL3034EIRTZ-T?
The ISL3034EIRTZ-T guarantees 100Mbps operation when VL ≥ 1.62V and push-pull drivers are used with RSOURCE = 150Ω and load capacitance ≤15pF. At VL = 1.35V, the maximum data rate is 85Mbps. These values are production-tested and specified in the FN6492 Rev.2.00 datasheet, page 4.
Does the ISL3034EIRTZ-T require external pull-up resistors?
No, the ISL3034EIRTZ-T integrates 30µA internal pull-up current sources on each I/OVL and I/OVCC pin during active operation, eliminating the need for external pull-ups in most open-drain applications like I²C. External resistors are only recommended for very high-speed open-drain signaling where rise time exceeds specification limits.
How does the auto-direction sensing work in the ISL3034EIRTZ-T?
Each channel in the ISL3034EIRTZ-T monitors transitions on either I/OVL or I/OVCC pins. A detected edge momentarily defines that pin as input, triggering accelerator circuitry to drive the corresponding opposite-side pin with level-shifted logic. After ~3–4ns, weak hold circuitry maintains state until next transition - enabling fully autonomous, bit-by-bit direction resolution without external control signals.
What happens to the ISL3034EIRTZ-T when VCC drops below VL?
When VCC falls below VL by more than 0.7V, the ISL3034EIRTZ-T automatically enters shutdown mode: all I/O pins tri-state, VCC supply current drops to ≤2.5µA, and VL supply current drops to ≤4µA. This behavior is defined in the VL–VCC shutdown threshold specifications (VTH_H and VTH_L) on datasheet page 4.
Is the ISL3034EIRTZ-T pin-compatible with other members of the ISL3034E family?
Yes, the ISL3034EIRTZ-T shares identical pinout and functionality with ISL3034EIRTZ (same 16-lead TQFN package, L16.3x3A outline). It is not pin-compatible with ISL3034EIRUZ-T, which uses a smaller 16-lead UTQFN (2.6mm×1.8mm) package with different land pattern and thermal pad configuration.
