Key Features
- 2-bit bidirectional FM+ I2C bus and SMBus voltage level translator supporting Fast-Mode Plus (FM+) speeds up to 1 MHz for high-speed serial interface level shifting
- Open-drain output architecture enables seamless bidirectional translation between different voltage domains without direction control signals, simplifying multi-voltage I2C bus designs
- Maximum 46ns propagation delay in a compact 8-pin WSON package with RoHS-compliant lead-free construction for space-constrained mixed-voltage embedded systems
Applications
The TCA39306DTMR is ideal for translating I2C and SMBus signals between 3.3V and 1.8V (or other mismatched voltage) domains in multi-rail SoC, FPGA, and microcontroller systems where peripherals operate at different supply voltages. It suits battery management systems, server board management controllers, and portable device sensor hubs requiring reliable FM+ I2C communication across voltage domains. Industrial IoT platforms and wearable electronics with mixed-voltage components also benefit from its low-latency bidirectional translation without the need for direction control logic.

Frequently Asked Questions
What bus protocols and speed does the TCA39306DTMR support?
The TCA39306DTMR supports FM+ (Fast-Mode Plus) I2C bus and SMBus protocols with speeds up to 1 MHz. It is backward compatible with standard-mode (100 kHz) and fast-mode (400 kHz) I2C, making it suitable for a wide range of I2C and SMBus slave and master devices operating at different speeds.
How does the TCA39306DTMR handle bidirectional translation without a direction pin?
The TCA39306DTMR uses open-drain output transistors on both ports that automatically detect the direction of data flow. When one side pulls the bus low, the translator propagates the low state to the other side within 46ns maximum, eliminating the need for an external direction control signal and simplifying firmware and hardware design in bidirectional I2C translation applications.
What package does the TCA39306DTMR come in?
The TCA39306DTMR is housed in an 8-pin WSON (PDSO-N8) surface-mount package with a plastic/epoxy body, identified by JESD-30 Code R-PDSO-N8. This compact no-lead package suits space-constrained PCB layouts in portable electronics, wearables, and high-density server boards requiring SMBus or I2C voltage translation.
Is the TCA39306DTMR RoHS compliant?
Yes, the TCA39306DTMR is lead-free and carries JESD-609 Code e4, confirming compliance with RoHS and halogen-free environmental regulations. This makes it suitable for consumer electronics, industrial systems, and automotive-adjacent applications where strict material compliance is required by regulation or customer specifications.
What are common applications for the TCA39306DTMR?
Typical applications include multi-voltage I2C bus bridging in SoC-based platforms, server BMC (baseboard management controller) SMBus interfaces, battery management system communication, portable device sensor hubs, and industrial IoT gateway boards. Any design mixing 1.8V, 2.5V, or 3.3V I2C or SMBus devices can use the TCA39306DTMR for reliable, low-latency bidirectional level translation.
