PCA9601DP,118

The PCA9601DP,118 from NXP Semiconductors is a dual bidirectional bus buffer that isolates I2C-bus capacitance, enabling longer buses in point-to-point or multipoint applications. It supports speeds up to 1 MHz and is compatible with Fast-mode Plus specifications.

This device creates a non-latching, bidirectional logic interface between a standard I2C-bus and other bus configurations with higher capacitance or different voltage levels. It features temperature-stabilized logic voltage levels at its SX/SY interface, making it suitable for interfacing with buses like SMBus or PMBus, or with microprocessors using TTL logic levels. The 15 mA drive capability at SX/SY allows driving a 5 V Fm+ bus with 470 pF loading.

The PCA9601DP,118 splits I2C-bus signals into unidirectional TX/RX pairs, facilitating transmission via balanced lines or galvanic isolation. It operates with a supply voltage range of 2.5 V to 15 V, with I2C-bus logic levels on the SX/SY side independent of the supply voltage.

Packaged in an 8-TSSOP, this surface-mount component is designed for applications requiring robust I2C communication over extended distances or across different voltage domains.
