PCA9306 Datasheet, PDF (1/12 Pages) Texas Instruments – DUAL BIDIRECTIONAL I2C BUS AND SMBus VOLTAGE-LEVEL TRANSLATOR

PCA9306
Dual Bidirectional I²C-bus
and SMBus Voltage-Level
Translator
The PCA9306 is a dual bidirectional I²C−bus and SMBus
voltage−level translator with an enable (EN) input.
Features
• 2−bit Bidirectional Translator for SDA and SCL Lines in
Mixed−Mode I²C−Bus Applications
• Standard−Mode, Fast−Mode, and Fast−Mode Plus I²C−Bus and
SMBus Compatible
• Less Than 1.5 ns Maximum Propagation Delay to Accommodate
Standard−Mode and Fast−Mode I²C−Bus Devices and Multiple
Masters
• Allows Voltage Level Translation Between:
♦ 1.0 V V_ref(1) and 1.8 V, 2.5 V, 3.3 V or 5 V V_bias(ref)(2)
♦ 1.2 V V_ref(1) and 1.8 V, 2.5 V, 3.3 V or 5 V V_bias(ref)(2)
♦ 1.8 V V_ref(1) and 3.3 V or 5 V V_bias(ref)(2)
♦ 2.5 V V_ref(1) and 5 V V_bias(ref)(2)
♦ 3.3 V V_ref(1) and 5 V V_bias(ref)(2)
• Provides Bidirectional Voltage Translation With No Direction Pin
• Low 3.5 W ON−State Connection Between Input and Output Ports
Provides Less Signal Distortion
• Open−Drain I²C−Bus I/O Ports (SCL1, SDA1, SCL2 and SDA2)
