PCA9600DP

双路双向总线缓冲器 Dual bidirectional bus buffer

The is a dual bidirectional Bus Buffer. The PCA9600 is designed to isolate I²C-bus capacitance, allowing long buses to be driven in point-to-point or multipoint applications of up to 4000pF. The PCA9600 is a higher-speed version of the P82B96. It creates a non-latching, bidirectional, logic interface between a normal I²C-bus and a range of other higher capacitance or different voltage bus configurations. It can operate at speeds up to at least 1MHz and the high drive side is compatible with the Fast-mode Plus Fm+ specifications. The PCA9600 features temperature-stabilized logic voltage levels at its SX/SY interface making it suitable for interfacing with buses that have non I²C-bus-compliant logic levels such as SMBus, PMBus or with microprocessors that use those same TTL logic levels.
