40-bit I2c-bus I/o Port With Reset, Oe, And Int - Nxp Semiconductors

The PCA9506 provides 40-bit parallel input/output (I/O) port expansion for I 2C-bus applications organized in 5 banks of 8 I/Os. At 5 V supply voltage, the outputs are capable of sourcing 10 mA and sinking 25 mA with a total package load of 800 mA to allow direct driving of 40 LEDs Any of the 40 I/O ports CAN be congured as an input or output. Output ports are totem-pole and their Logic state changes at the Acknowledge (bank change). The device CAN be congured to have each input port to be masked in order to prevent it from generating interrupts when its state changes and to have the I/O data Logic state to be inverted when read by the system master. An open-drain interrupt (INT) output pin allows monitoring of the input pins and is asserted each time a change occurs in one or several input ports (unless masked). The Output Enable (OE) pin 3-states any I/O selected as output and CAN be used as an input signal to blink or dim LEDs (PWM with frequency > 80 Hz and change duty cycle). The internal Power-On Reset (POR) or hardware reset (RESET) pin initializes the 40 I/Os as inputs. Three address select pins congure one of 8 slave addresses. The PCA9506 is available in 56-pin TSSOP and HVQFN packages and is specied over the 40 Cto+85 C industrial temperature range. By NXP Semiconductors
