Translators, Level Shifters datasheet and documents for TCA39306DCUR

TCA39306DCUR

Translators, Level Shifters Overview

The TCA39306DCUR is a dual bidirectional voltage-level translator compatible with I2C, SMBus, and I3C protocols. It operates with VREF1 ranging from 0.85 V to 3.3 V and VREF2 from 1.8 V to 5.5 V. The device provides translation between these levels without a direction pin. It features an enable input for isolation and supports standard, fast, and fast-mode plus speeds. Propagation delays range from 1.2 ns to 46 ns depending on load conditions. It is housed in an 8-pin VSSOP package.

Translators, Level Shifters Feature Summary

Bidirectional voltage translation between low-voltage (VREF1) and high-voltage (VREF2) domains without requiring a direction control pin.
Integrated enable (EN) input allows the device to function as a switch, isolating bus segments by entering a high-impedance state when disabled.
Low on-state resistance minimizes signal distortion and propagation delay across SDA and SCL lines.
ESD protection rated at 2000 V human-body model and 1000 V charged-device model.

Translators, Level Shifters Procurement Notes

Verify the DCUR suffix indicates the VSSOP-8 package and tape-and-reel delivery format. Confirm that the specific revision of the datasheet matches the production lot requirements. Ensure the design accounts for the 200-kΩ internal pull-up resistor behavior on the VREF2 pin during setup. Validate thermal performance within the specified ambient temperature range for the selected enclosure.

Translators, Level Shifters Selection Notes

Select this component when interfacing mixed-voltage I2C or SMBus devices where bidirectional data flow is required. It is suitable for applications needing bus isolation via the EN pin to prevent glitches during hot-plugging or speed mismatches. Ensure the system voltages fall within the supported VREF1 and VREF2 ranges. Consider the VSSOP-8 footprint constraints during PCB layout.

Translators, Level Shifters Part Context

This part belongs to the TCA39306 family of voltage translators. It is distinct from automotive-grade variants like the TCA39306DCURQ1. The device serves as a bridge for legacy and modern low-speed serial interfaces. It replaces discrete transistor solutions by offering symmetrical electrical characteristics and simplified routing through its flow-through pinout.
