Product details
Overview
ISL3036EIRZ-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) 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 ensures robustness in exposed interface applications.
For engineers reviewing the ISL3036EIRZ-T7A datasheet, ISL3036EIRZ-T7A pinout, ISL3036EIRZ-T7A application, or ISL3036EIRZ-T7A equivalent, key selection considerations include its auto-direction sensing architecture, 100Mbps data rate at VL ≥ 1.62V, 16-lead µTQFN (2.6mm × 1.8mm) package, shutdown current < 4µA, and compatibility with both push-pull and open-drain drivers.
Technical Context
The ISL3036EIRZ-T7A implements a channel-level auto-direction sensing mechanism using high/low threshold detectors and one-shot-controlled PMOS/NMOS accelerator drivers that actively drive outputs for ~3–4ns before reverting to weak hold mode. Each channel independently detects transitions on either I/OVL or I/OVCC pins to determine real-time signal direction without external control.
It features dual-supply operation with independent VL and VCC rails, internal 30µA pull-up current sources per I/O in active mode, and 10–23kΩ pull-up resistors during shutdown. The device enters automatic shutdown when VCC falls below VL + 0.2V or EN is driven low, tri-stating all I/Os and reducing supply current to sub-4µA.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Data Rate | 100Mbps at VL ≥ 1.62V - supports high-speed serial interfaces like I²C fast-mode+, SPI, and GPIO expansion between mixed-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 level-shifting overhead. |
| ESD Protection | ±15kV IEC61000-4-2 air-gap on all I/O and EN pins - eliminates need for external TVS diodes in card-edge or connector-facing designs. |
| Propagation Delay | ≤6.5ns (I/OVL → I/OVCC), ≤7.5ns (I/OVCC → I/OVL) - enables timing-critical applications such as memory address/data buses and real-time control signals. |
| Shutdown Current | <4µA total (VL + VCC) - suitable for battery-powered systems requiring ultra-low quiescent power during sleep modes. |
| Package | 16-lead µTQFN (2.6mm × 1.8mm, 0.5mm pitch) - compact footprint ideal for space-constrained portable and wearable electronics. |
Pinout & Package
ISL3036EIRZ-T7A is housed in a 16-lead ultra-thin quad flat no-lead (µTQFN) package measuring 2.6mm × 1.8mm with an exposed thermal pad. Pin numbering follows standard top-view orientation with pin 1 marked by a dot or beveled corner.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC | High-side power supply | Provides +2.2V to +3.6V bias for I/OVCC channels; must exceed VL by ≥200mV for normal operation. |
| VL | Low-side power supply | Provides +1.35V to +3.2V bias for I/OVL channels; powers EN circuitry and defines low-voltage logic thresholds. |
| GND | Ground reference | Common return path for both supplies; requires low-inductance connection to PCB ground plane for ESD and noise immunity. |
| EN | Enable input | Active-high control: logic low places all I/Os in tri-state shutdown; internally referenced to VL for robust start-up sequencing. |
| I/OVL1–I/OVL6 | Bidirectional I/O (VL-referenced) | Interface with low-voltage devices; VOH tracks VL, VOL sinks to GND; accepts 0.15V–(VL−0.2V) input thresholds. |
| I/OVCC1–I/OVCC6 | Bidirectional I/O (VCC-referenced) | Interface with high-voltage devices; VOH tracks VCC, VOL sinks to GND; accepts 0.2V–(VCC−0.4V) input thresholds. |
Key Features
| Feature | Design Value |
|---|---|
| Auto-direction sensing per channel | Eliminates requirement for dedicated DIR pins or GPIO-controlled direction logic, reducing MCU pin count and firmware complexity. |
| Integrated 30µA pull-up current sources | Removes need for external pull-ups on open-drain buses (e.g., I²C), simplifying BOM and layout while maintaining rise time control. |
| Accelerator-based output drivers | Delivers <4ns active drive pulses with <10Ω sink/source impedance, enabling reliable 100Mbps operation even with 15pF load capacitance. |
| Automatic VCC/VL supply monitoring | Enters safe shutdown if VCC drops below VL + 0.2V, preventing latch-up or undefined behavior during power sequencing mismatches. |
| ±15kV IEC61000-4-2 ESD on all pins | Enables direct placement on board edges or connector interfaces without supplemental protection components, saving board area and cost. |
Applications
| Memory Card Interface | Multi-Voltage Microcontroller Expansion |

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, 5V-tolerant I/O, fixed 1.2V–3.6V VL range, no auto-direction sensing - requires external DIR control. | Requires additional MCU GPIO and firmware logic for direction management; better suited for synchronous, unidirectional-heavy protocols like parallel buses. | Select TXS0108E only when 8 channels are needed and direction control is available; ISL3036EIRZ-T7A offers superior flexibility for mixed-direction traffic with zero GPIO overhead. |
| SN74AVC16T245 | 16-bit, dual-supply, direction-controlled, no auto-sensing, higher ICC (≈50µA active), larger TSSOP package. | Designed for wide-bus applications (e.g., memory data paths); lacks integrated ESD protection beyond HBM, requiring external TVS diodes for IEC61000-4-2 compliance. | Choose SN74AVC16T245 for high-pin-count parallel interfaces where board space permits larger packages and ESD protection is handled at system level. |
Compared with TXS0108E and SN74AVC16T245, the ISL3036EIRZ-T7A delivers unique value through per-channel auto-direction sensing, best-in-class ±15kV IEC61000-4-2 protection, and ultra-low shutdown current in a miniature µTQFN package - making it optimal for compact, mixed-protocol, and ESD-critical embedded interfaces.

FAQ
What is the maximum data rate supported by the ISL3036EIRZ-T7A?
The ISL3036EIRZ-T7A supports up to 100Mbps when VL ≥ 1.62V and uses push-pull drivers with 150Ω source impedance and ≤15pF load capacitance. At VL = 1.35V, the guaranteed maximum data rate drops to 85Mbps. These values are measured per channel and reflect worst-case timing across temperature and voltage ranges.
Does the ISL3036EIRZ-T7A require external pull-up resistors for I²C operation?
No, the ISL3036EIRZ-T7A 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 standard I²C fast-mode+ (1Mbps) applications. External resistors may be added only for specialized high-capacitance or ultra-high-speed scenarios beyond 100Mbps.
Can the ISL3036EIRZ-T7A operate with VL greater than VCC?
Yes - the ISL3036EIRZ-T7A tolerates VL > VCC during power-up and shutdown without damage or latch-up. However, normal bidirectional translation requires VCC > VL + 0.2V. If VL exceeds VCC by more than 0.7V, the device automatically enters shutdown mode, tri-stating all I/Os until VCC rises sufficiently.
What package type is used for the ISL3036EIRZ-T7A?
The ISL3036EIRZ-T7A uses a 16-lead ultra-thin quad flat no-lead (µTQFN) package measuring 2.6mm × 1.8mm with 0.5mm pitch and an exposed thermal pad. This RoHS-compliant package is optimized for high-density PCB layouts and thermal performance in portable electronics.
How does the auto-direction sensing work in the ISL3036EIRZ-T7A?
Each channel in the ISL3036EIRZ-T7A monitors both I/OVLx and I/OVCCx pins for voltage transitions. Upon detecting a rising or falling edge on either pin, the internal accelerator circuit momentarily defines that pin as input, shifts the logic level across the supply domains, and drives the corresponding output pin. After ~3–4ns, weak hold circuitry maintains the state until the next transition occurs - all without external direction control.
