NXP PCA9505DGGY I/O Expander, 40 bit, I2C, 2.3 V, 5.5 V, TSSOP, 56 Pins

PCA9505DGGY is a 40-bit I²C-bus I/O port with RESET, OE and INT. It provides 40bit parallel input/output (I/O) port expansion for I²Cbus applications organized in 5 banks of 8 I/Os. At 5V supply voltage, the outputs are capable of sourcing 10mA and sinking 15mA with a total package load of 600mA 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 100Kohm internal pull-up resistors on all the I/Os. The device can be configured 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 controller. Application includes servers, RAID systems, industrial control, medical equipment, PLCs, cell phones, gaming machines, instrumentation and test measurement.

• Standard mode (100KHz) and Fast mode (400KHz) compatible I²C-bus serial interface
• 2.3V to 5.5V operation with 5.5V tolerant I/Os
• 40 configurable I/O pins that default to inputs at power-up
• 40 configurable I/O pins that default to inputs at power-up
• Active LOW reset (RESET, active low) input pin resets device to power-up default state
• 3 programmable address pins allowing 8 devices on the same bus
• Minimize line disturbance (IOFF and power-up 3-state)
• Signal transient rejection (50 ns noise filter and robust I2C-bus state machine)
• Latch-up testing is done to JEDEC Standard JESD78, which exceeds 100mA
• TSSOP56 package, temperature range from -40°C to +85°C
