PCA9601
Dual bidirectional bus buffer
Rev. 3 — 24 September 2015
Product data sheet
1. General description
The PCA9601 is designed to isolate I2C-bus capacitance, allowing long buses to be driven in point-to-point or multipoint applications of up to 4000 pF. The PCA9601 is a higher-speed version of the P82B96 and a higher drive version of the PCA9600 that allows many more Fast-mode Plus (Fm+) slaves on remote daughter cards in applications with temperature range of 0 C to 85 C.
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 1 MHz, and the high drive side is compatible with the Fast-mode Plus specifications.
