PCA9601D: Dual bidirectional bus buffer
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.
The PCA9601 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.
15 mA drive capability over 0 °C to 85 °C at SX/SY allows driving a 5 V Fm+ bus with
470 pF loading.
The separation of the bidirectional I²C-bus signals into unidirectional TX and RX signals
enables the SDA and SCL signals to be transmitted via balanced transmission lines
(twisted pairs), or with galvanic isolation using opto or magnetic coupling. The TX and RX
signals may be connected together to provide a normal bidirectional signal.
