PCA9621 Description

The PCA9621 is a monolithic CMOS integrated circuit for general purpose output drive configurable from a 2-wire bus interface (including I2C-bus, SMBus, PMBus, and other systems based on similar principles). Output ports have a 65 mA sink capability, making them ideal for driving LEDs. The state of the outputs is determined by a programmable 8-bit register which can be read and written via signals from the 2-wire...

PCA9621 Key Features

  • 8 individually selectable open-drain output ports 65 mA static sink capability on all output ports Ports may be parallel
  • Fast switching times allow operation in excess of 1 MHz
  • Operating voltages from 2.7 V to 5.5 V
