NXP PCA9506DGG,518

40I²CPOR2.3V ~ 5.5V-40°C ~ 85°C

Overview

The PCA9505/PCA9506 provide 40-bit parallel input/output (I/O) port expansion for I²C-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 15 mA with a total package load of 600 mA to allow direct driving of 40 LEDs. Any of the 40 I/O ports can be configured as an input or output. Output ports are totem-pole and their logic state changes at the Acknowledge (bank change). The PCA9505 is identical to the PCA9506 except that it includes 100 kΩ internal pull-up resistors on all the I/Os. The PCA9506 does not include the internal pull-ups on the I/Os to reduce power consumption when used as outputs or when the input is driven by a push-pull driver.

The PCA9506 is available in 56-pin TSSOP and HVQFN packages, while the PCA9505 is available only in a TSSOP package. They are both specified over the -40 Cel to +85 Cel industrial temperature range.
