Simple impedance isolating buffer for 2-wire buses 30 mA maximum static open-drain pull-down capability supports a wide range of busstandards Works with I2C-bus (Standard-mode, Fast-mode, Fast-mode Plus), SMBus (standardand high power mode), and PMBus Fast switching times allow operation in excess of 1 MHz Enable allows bus segments to be disconnected Hysteresis on inputs provides noise immunity Operating voltages from 2.7 V to 5.5 V Very low supply current Uncomplicated characteristics suitable for quick implementation in most common2-wire bus applications
The PCA9605 is a monolithic CMOS integrated circuit for bus buffering in applicationsincluding I2C-bus, SMBus, DDC, PMBus, and other systems based on similar principles.The buffer extends the bus load limit by buffering both the SCL and SDA lines, allowingthe maximum permissible bus capacitance on both sides of the buffer.The PCA9605 includes a unidirectional buffer for the clock signal, and a bidirectionalbuffer for the data signal. Slave devices which employ clock stretching are therefore notsupported.In its most basic implementation, the buffer will allow an extended number of slavedevices to be attached to one (or more) master devices. In this case, all master deviceswould be positioned on the Sxx_IN side of the PCA9605.The direction pin (DIR) further enhances this function by allowing the unidirectional clocksignal to be reversed, thus allowing master devices on both sides of the buffer.The enable (EN) function allows sections of the bus to be isolated. Individual parts of thesystem can be brought on-line successively. This means a controlled start-up using adiverse range of components, operating speeds and loads is easily achieved.
