Product Summary

The PCA9306DCTR is a dual bidirectional I2C bus and SMBus voltage-level translator. The PCA9306DCTR allows bidirectional voltage translations between 1.2 V and 5V, without the use of a direction pin. The PCA9306DCTR also can be used to run two buses, one at 400-kHz operating frequency and the other at 100-kHz operating frequency.

Parametrics

PCA9306DCTR absolute maximum ratings: (1) DC reference voltage range VREF1: -0.5 to 7V; (2) DC reference bias voltage range VREF2: -0.5 to 7V; (3) Input/output voltage range VI/O: -0.5 to 7V; (4) Input voltage range VI: -0.5 to 7V; (5) Continuous channel current: 128mA; (6) Input clamp current IIK: -50mA (VI< 0) ; (7) Storage temperature range: -65 to +150°C.

Features

PCA9306DCTR 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 ast-Mode I2C Devices and Multiple Masters; (4) Provides Bidirectional Voltage Translation With No Direction Pin; (5) Low 3.5-Ω ON-State Connection Between Input and Output Ports Provides Less Signal Distortion; (6) High-Impedance SCL1, SDA1, SCL2, and SDA2 Pins for EN=Low; (7) Flow-Through Pinout for Ease of Printed Circuit Board Trace Routing; (8) ESD Protection Exceeds JESD 22.
