Description
PCA9509 Level translating I2C-bus/SMBus repeater Rev.7 * 4 November 2014 Product data sheet 1.General .Features
* Bidirectional buffer isolates capacitance and allows 400 pF on port B of the deviceApplications
* where Port A VCC(A) is less than 1.35 V or Port B VCC(B) is less than 3.0 V, use drop-in replacement PCA9509A. The bus port B drivers are compliant with SMBus I/O levels, while port A uses a current sensing mechanism to detect the input or output LOW signal which prevents bus lock-up. Port A uses aPCA9509 Distributors
