Overview
The PCA9600D,112 is a dual bidirectional bus buffer designed by NXP USA Inc. This component is specifically engineered to isolate I²C-bus capacitance, enabling the operation of long buses in both point-to-point and multipoint configurations. It is a higher-speed version of the P82B96 and supports bus capacitances up to 4000 pF. The PCA9600D,112 operates at speeds up to at least 1 MHz and is compatible with the Fast-mode Plus (Fm+) specifications, making it suitable for a wide range of applications requiring reliable and high-speed I²C-bus communication.

Key Features
- Bidirectional data transfer of I²C-bus signals, creating a non-latching, logic interface between a normal I²C-bus and higher capacitance or different voltage bus configurations.
- Operates at speeds up to at least 1 MHz and is compatible with Fast-mode Plus (Fm+) specifications.
- 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 TTL logic levels.
- Splits I²C-bus signals into pairs of forward/reverse TX/RX, TY/RY signals for interface with opto-electrical isolators and similar devices.
- Low power supply current and high drive capability for driving low-impedance or high capacitive buses.
- ESD protection exceeds 3500 V HBM per JESD22-A114, 250 V DIP package, 400 V SO package MM per JESD22-A115, and 1000 V CDM per JESD22-C101.
- Latch-up free (bipolar process with no latching structures).
Applications
- Interface between I²C-buses operating at different logic levels (e.g., 5 V and 3 V or 15 V).
- Interface between I²C-bus and SMBus (350 µA) standard.
- Simple conversion of I²C-bus SDA or SCL signals to multi-drop differential bus hardware.
- Interfaces with opto-couplers to provide opto-isolation between I²C-bus nodes up to 400 kHz.
- Long-distance I²C-bus communication in point-to-point or multipoint configurations.
