Renesas ISL3036EIRUZ-T7A

Overview

ISL3036EIRUZ-T7A 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 ISL3036EIRUZ-T7A datasheet, ISL3036EIRUZ-T7A pinout, ISL3036EIRUZ-T7A application, or ISL3036EIRUZ-T7A equivalent, key selection considerations include its auto-direction sensing architecture, 16.5kΩ shutdown pull-up resistance per I/O, 6.5ns typical propagation delay (I/OVL → I/OVCC), 3.2ns rise/fall times, and compatibility with both push-pull and open-drain drivers without external direction control logic.

Technical Context

The ISL3036EIRUZ-T7A implements a channel-level auto-direction sensing mechanism using high/low threshold detectors and one-shot-triggered large-output drivers that actively drive the opposite-side I/O for ~3–4ns before transitioning to weak hold mode via internal current sources or NMOS pass transistors. Each channel operates independently, eliminating need for global DIR pins.

It features dual-supply operation with independent VL and VCC rails, automatic shutdown when VCC falls below VL + 200mV, and integrated 30µA active-mode pull-up current sources per I/O - enabling direct interface with 4mA-output drivers and robust performance under capacitive loads up to 35pF.

FAQ

What is the maximum data rate supported by the ISL3036EIRUZ-T7A?

The ISL3036EIRUZ-T7A supports a guaranteed maximum data rate of 100Mbps under push-pull driver conditions with VL ≥ 1.62V, RSOURCE = 150Ω, and CL ≤ 15pF. At VL = 1.35V, the rated speed drops to 85Mbps. This makes ISL3036EIRUZ-T7A suitable for I²C Fast Mode Plus (1Mbps), SPI (≥50MHz clock), and other high-speed bidirectional protocols.

Does the ISL3036EIRUZ-T7A require external pull-up resistors?

No - the ISL3036EIRUZ-T7A integrates 30µA active-mode pull-up current sources on all I/OVL and I/OVCC pins, eliminating the need for external pull-ups in most push-pull or open-drain configurations. External resistors are only recommended for very high-speed open-drain signaling (>100Mbps) or unusually heavy capacitive loads (>35pF).

How does the auto-direction sensing work in the ISL3036EIRUZ-T7A?

Each ISL3036EIRUZ-T7A channel uses independent high/low threshold detectors and one-shot-triggered output drivers. A transition on either I/OVL or I/OVCC momentarily defines that pin as input, shifts the level, and actively drives the opposite-side pin for ~3–4ns. Afterward, weak hold circuitry maintains the state until the next edge - all without external DIR signals.

What happens when VCC falls below VL on the ISL3036EIRUZ-T7A?

When VCC drops below VL + 200mV, the ISL3036EIRUZ-T7A automatically enters low-power shutdown mode: all I/O pins tri-state, and internal 16.5kΩ pull-up resistors connect I/OVL to VL and I/OVCC to VCC. This behavior prevents bus contention and protects downstream logic during asymmetric power sequencing.

Is the ISL3036EIRUZ-T7A pin-compatible with the ISL3034E?

Yes - ISL3036EIRUZ-T7A shares identical pinout, package (16L µTQFN, 2.6mm × 1.8mm), and electrical specifications with ISL3034E. Both devices are functionally equivalent; ISL3036EIRUZ-T7A is a Renesas-marketed variant of the same silicon die, confirmed in FN6492 Rev.2.00 ordering table and pin configuration diagrams.
