CCB 2 2 I C-Bus and SMBus Compatible C-bus systems, pull-up resistors are As with standard I required to provide the logic HIGH levels on the Less than 1.5ns Maximum Propagation Delay translators bus. The FXWA9306 has a standard open- to Accommodate Standard-Mode and Fast-Mode 2 2 drain configuration of the I C-bus. The size of these pull- I C-Bus Devices and Multiple Masters up resistors depends on the system, but each side of Allows Voltage Level Translation Between: the translator must have a pull-up resistor. The device is designed to work with Standard-Mode, Fast-Mode, and VCCA = 1.0 to 3.6V and VCCB = 1.8- 5.0V 2 Fast Mode Plus I C-bus devices in addition to SMBus 2 Supports I C Clock Stretching and Multi-Master devices. The maximum frequency is dependent on the RC time constant, but generally supports > 2MHz. Provides Bi-directional Voltage Translation without Direction Pin All channels have the same electrical characteristics and there is a minimum deviation from one output to Low 3.5 On-State Connection Between Input and another in voltage or propagation delay. This is a benefit Output Ports Provides Less Signal Distortion over discrete transistor voltage translation solutions, 2 Open-Drain I C-Bus I/O Ports (A0, A1, B0, and B1) since the fabrication of the switch is symmetrical. The 2 translator provides excellent ESD protection to lower 5V-Tolerant I C-Bus I/O Ports to Support Mixed- voltage devices and at the same time protects less-ESD Mode Signal Operation resistant devices.
