PCA9672BS

General descriptionThe PCA9672 provides general purpose remote I/O expansion for most microcontroller families via the two-line bidirectional bus (I2C-bus) and isA part of the Fast-mode Plus family.The PCA9672 isA drop-in upgrade for the PCF8574 providing higher Fast-mode Plus (Fm+) I2C-bus speeds (1 MHz versus 400 kHz) so that the output can support PWM dimming of LEDs, higher I2C-bus drive (30 mA versus 3 mA) so that many more devices can be on the bus without the need for bus buffers, higher total pack
