Renesas ISL3036EIRUZ-T

Overview

ISL3036EIRUZ-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 supplies. 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 system interconnects.

For engineers reviewing the ISL3036EIRUZ-T datasheet, ISL3036EIRUZ-T pinout, ISL3036EIRUZ-T application, or ISL3036EIRUZ-T equivalent, key selection considerations include its auto-direction sensing architecture, 16 Ld UTQFN (2.6mm × 1.8mm) package with thermal pad, shutdown current <4µA, and compatibility with both push-pull and open-drain drivers requiring ≥4mA output drive.

Technical Context

The ISL3036EIRUZ-T implements per-channel bit-by-bit auto-direction sensing using high/low threshold detectors and one-shot controlled large-swing accelerator drivers that actively drive outputs to rail or GND for ≤4ns before transitioning to weak hold mode. This architecture eliminates direction control pins while enabling robust operation with open-drain sources and fast propagation delays (≤7.5ns).

It features dual independent supply domains: VL powers I/OVL pins and EN logic, while VCC powers I/OVCC pins and internal accelerators. Automatic shutdown activates when EN = GND or when VL > VCC + 0.7V, tri-stating all I/Os and reducing supply currents to sub-4µA levels. Internal 30µA pull-up current sources on each I/O line eliminate need for most external bus resistors.

FAQ

What is the maximum data rate supported by the ISL3036EIRUZ-T?

The ISL3036EIRUZ-T supports a guaranteed maximum data rate of 100Mbps under push-pull driving conditions with VL ≥ 1.62V, RSOURCE = 150Ω, and load capacitance ≤15pF. At VL = 1.35V, the rated speed is 85Mbps. These values are production-tested and specified in the Electrical Specifications table of the FN6492 Rev.2.00 datasheet.

Does the ISL3036EIRUZ-T require external pull-up resistors?

No, the ISL3036EIRUZ-T integrates 30µA internal pull-up current sources on each I/OVL and I/OVCC pin during active operation, eliminating the need for most external pull-ups. External resistors are only recommended for high-speed open-drain signaling with heavy capacitive loads (>35pF) or when faster rise times are required beyond what the internal current source provides.

How does the automatic shutdown feature work in the ISL3036EIRUZ-T?

The ISL3036EIRUZ-T enters low-power shutdown when EN is driven low OR when VL exceeds VCC by more than 0.7V. In shutdown, all I/O pins are tri-stated and supply currents drop to ≤2.5µA (ICCSD) and ≤4µA (ILSD). The VL supply remains active to monitor EN and VCC, enabling fast wake-up when valid supply conditions resume.

Can the ISL3036EIRUZ-T translate between 1.5V and 3.3V logic domains?

Yes, the ISL3036EIRUZ-T supports VL = +1.35V to +3.2V and VCC = +2.2V to +3.6V, making 1.5V-to-3.3V translation fully compliant. The device requires VCC > VL + 0.2V for normal operation, which holds true for this combination. Input thresholds scale with supply voltages, ensuring reliable switching across the full range.

Is the ISL3036EIRUZ-T pin-compatible with the ISL3034EIRTZ-T?

No, the ISL3036EIRUZ-T is not pin-compatible with the ISL3034EIRTZ-T. While both are 6-channel translators from the same family, ISL3036EIRUZ-T uses the 16 Ld UTQFN (2.6mm × 1.8mm) package, whereas ISL3034EIRTZ-T uses the larger 16 Ld TQFN (3mm × 3mm) package with different pin assignments. Board redesign is required for substitution.
