PCA9600
Dual bidirectional bus buffer
3. Applications
 Interface between I
2
C-buses operating at different logic levels (for example, 5 V and
3V or 15V)
 Interface between I
2
C-bus and SMBus (350 μA) standard or Fm+ standard
 Simple conversion of I
2
C-bus SDA or SCL signals to multi-drop differential bus
hardware, for example, via compatible PCA82C250
 Interfaces with opto-couplers to provide opto-isolation between I
2
C-bus nodes up to
1MHz
 Long distance point-to-point or multipoint architectures
