PCA9306DQER - Brand New Texas Instruments Translators / Level Shifters
-
Description
The PCA9306DQER is an I2C-bus voltage level translator that provides bidirectional level translation for low-cost and space-constrained applications.
It is designed for translating the low-voltage control signals, such as those found in microcontrollers, between devices operating at different I2C-bus voltage levels.
This voltage level translator can operate from 1.2 V to 3.6 V, allowing the system designer to interface standard low-voltage devices, such as an FPGA or microcontroller, to the I2C-bus without the need for an external voltage-level shifter.
Specifications and features
- Bidirectional voltage-level translation between 1.2 V and 3.6 V
- No direction pin required
- Open-drain input/outputs
- Lock-up-free operation
- Active LOW operation
- Typical propagation delay: 5 ns
- Max data rate: 400 kHz
- ESD protection exceeds JESD 22
- ESD protection exceeds 2000 V HBM, 200 V MM
Application Scenarios
The PCA9306DQER is ideal for low-cost and space-constrained applications where bidirectional level translation is required between devices operating at different I2C-bus voltage levels. Some possible uses include:
- Interfacing microcontrollers with different voltage levels to the I2C-bus
- Level shifting between devices with different supply voltages
- Transferring data between DSPs or MCUs operating at different voltage levels
