Renesas ISL3036EIRZ-TK

Overview

ISL3036EIRZ-TK 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 I²C peripherals) and higher-voltage system interfaces (e.g., 3.3V host controllers), with ±15kV IEC61000-4-2 ESD protection on all I/O pins.

For engineers reviewing the ISL3036EIRZ-TK datasheet, ISL3036EIRZ-TK pinout, ISL3036EIRZ-TK application, or ISL3036EIRZ-TK equivalent, key selection considerations include its auto-direction sensing architecture eliminating external direction control, 100Mbps guaranteed data rate at VL ≥ 1.62V, integrated 30µA pull-up current sources per channel, shutdown mode with <2.5µA VCC supply current, and compatibility with both push-pull and open-drain drivers.

Technical Context

The ISL3036EIRZ-TK implements a dual-rail, accelerator-based level-shifting architecture with independent high/low threshold detectors, one-shot triggered PMOS/NMOS output drivers, and weak hold circuitry. Each channel dynamically senses transition direction on either I/OVL or I/OVCC pins without external control, enabling bit-by-bit bidirectional translation.

It features active acceleration for fast rise/fall times (≤3.2ns), internal 16.5kΩ pull-up resistors during shutdown, and automatic shutdown when VCC falls below VL by >200mV. The device maintains signal integrity across wide capacitive loads (up to 35pF) while delivering sub-7.5ns propagation delay and <1.3ns channel-to-channel skew.

FAQ

What is the maximum data rate supported by the ISL3036EIRZ-TK?

The ISL3036EIRZ-TK guarantees 100Mbps data rate when VL ≥ 1.62V and uses push-pull drivers with 150Ω source impedance and ≤15pF load capacitance. At VL = 1.35V, the minimum guaranteed rate drops to 85Mbps. These values are production-tested and specified across the full -40°C to +85°C operating temperature range, ensuring consistent performance in industrial environments.

Does the ISL3036EIRZ-TK require external pull-up resistors?

No, the ISL3036EIRZ-TK 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 push-pull or lightly loaded open-drain configurations. 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 auto-direction sensing work in the ISL3036EIRZ-TK?

The ISL3036EIRZ-TK uses per-channel threshold detectors and one-shot accelerators: a transition on either I/OVL or I/OVCC momentarily defines that pin as input, triggers level-shifted driving on the opposite side, then reverts to weak hold mode. This enables true bit-by-bit direction detection without external control signals - critical for protocols like I²C where direction changes mid-transaction.

What is the shutdown behavior of the ISL3036EIRZ-TK when VCC falls below VL?

The ISL3036EIRZ-TK automatically enters low-power shutdown mode when VCC drops below VL by more than 200mV, tri-stating all I/O pins and reducing VCC supply current to <2.5µA. This feature protects downstream circuits during power sequencing mismatches and prevents bus contention during brown-out conditions - a key reliability advantage in multi-rail systems.

Is the ISL3036EIRZ-TK pin-compatible with the ISL3034E series?

Yes, the ISL3036EIRZ-TK shares identical pinout, package dimensions (16-lead µTQFN, 2.6mm × 1.8mm), and electrical specifications with the ISL3034E family, including matching VCC/VL supply ranges, ESD ratings, and timing parameters. It is a direct replacement offering the same functionality and layout compatibility - confirmed by Renesas' official ordering information and package drawings.
