Product Summary

The PCA9306DCUR is a dual bidirectional I2C and SMBus voltage-level translator. With an enable (EN) input, it is operational from 1.2-V to 3.3-V VREF1 and 2.5-V to 5.5-V VREF2. The PCA9306DCUR allows bidirectional voltage translations between 1.2 V and 5 V, without the use of a direction pin.

Parametrics

PCA9306DCUR absolute maximum ratings: (1)DC reference voltage range: –0.5 to 7 V; (2)DC reference bias voltage range: –0.5 to 7 V; (3)Input voltage range: –0.5 to 7 V; (4)Input/output voltage range: –0.5 to 7 V; (5)Continuous channel current: 128 mA; (6)IIK Input clamp current: VI < 0: –50 mA; (7)Package thermal impedance: DCT package: 220 ℃/W, DCU package 227 ℃/W; (8)Storage temperature range: –65 to 150 ℃.

Features

PCA9306DCUR features: (1)2-Bit Bidirectional Translator for SDA and SCL Lines in Mixed-Mode I2C Applications; (2)I2C and SMBus Compatible; (3)Less Than 1.5-ns Maximum Propagation Delay to Accommodate Standard-Mode and Fast-Mode I2C Devices and Multiple Masters; (4)Provides Bidirectional Voltage Translation With No Direction Pin; (5)Low 3.5-W ON-State Connection Between Input and Output Ports Provides Less Signal Distortion; (6)Open-Drain I2C I/O Ports (SCL1, SDA1, SCL2, and SDA2); (7)5-V Tolerant I2C I/O Ports to Support Mixed-Mode Signal Operation; (8)High-Impedance SCL1, SDA1, SCL2, and SDA2 Pins for EN = Low.
