PCA9306-Q1 Dual Bidirectional I2C Bus and SMBus Voltage-Level Translator

1 Features

AEC-Q100 qualified for automotive applications
- Temperature grade 2: –40°C to 105°C, T_A
- HBM ESD classification level H2
- CDM ESD classification level C4B
2-Bit bidirectional translator for SDA and SCL lines in mixed-mode I²C applications
Compatible with I²C and SMBus
Less than 1.5-ns maximum propagation delay to accommodate standard-mode and fast-mode I²C devices and multiple controllers
Allows voltage-level translation between
- 1.2-V V_REF1 and 1.8-V, 2.5-V, 3.3-V, or 5-V V_REF2
- 1.8-V V_REF1 and 2.5-V, 3.3-V, or 5-V V_REF2
- 2.5-V V_REF1 and 3.3-V, or 5-V V_REF2
- 3.3-V V_REF1 and 5-V V_REF2
Provides bidirectional voltage translation with no direction pin
Low 3.5-Ω ON-state connection between input and output ports provides less signal distortion
Open-drain I²C I/O Ports (SCL1, SDA1, SCL2, and SDA2)
5-V tolerant I²C I/O ports to support mixed-mode signal operation
High-impedance SCL1, SDA1, SCL2, and SDA2 pins for EN = low
Lock-up-free operation for isolation when EN = Low
Flow-through pinout for ease of printed-circuit board trace routing
Latch-up performance exceeds 100 mA Per JESD 78, Class II
ESD protection exceeds JESD 22
