NXP Semiconductors PCA9600 and PCA9601 Dual Bidirectional Bus Buffers are 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 and PCA9601 create a non-latching, bidirectional, logic interface between a normal I2C-bus and a range of other higher capacitance or different voltage bus configurations. These devices operate at speeds up to 1MHz, and the high drive side is compatible with the Fast-mode Plus (Fm+) specifications. The PCA9601 features 15mA SX/SY sink capability, yielding a 5V Fm+ bus rise time with 470pF loads.
The PCA9600 and PCA9601 Bus Buffers feature temperature-stabilized logic voltage levels at the SX/SY interface making these devices 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.
The NXP Semiconductors PCA9600 and PCA9601 Dual Bidirectional Bus Buffers are offered in SO8 and TSSOP8 (MSOP8) packages with a -40°C to +85°C operating temperature range.
