Description
The PCA9506DGG is an I/O Expander electronic component that provides a 40-bit parallel input/output (I/O) port expansion for I2C-bus applications organized into 5 banks of 8 I/Os. This component is capable of sourcing 10 mA and sinking 25 mA with a total package load of 800 mA to allow direct driving of 40 LEDs. With this component, any of the 40 I/O ports can be configured as an input or output with output ports being totem-pole and their logic state changing at the Acknowledge (bank change).
Specifications and features
- Standard mode (100 kHz) and Fast mode (400 kHz) compatible I2C-bus serial interface
- 2.3 V to 5.5 V operation with 5.5 V tolerant I/Os
- 40 configurable I/O pins that default to inputs at power-up
- Output ports with a controlled edge rate output structure that are totem-pole and capable of sourcing 10 mA and sinking 25 mA
- Active LOW output enable (OE) input pin 3-states all outputs with output state change on Acknowledge
- Open-drain active LOW interrupt (INT) output pin allows monitoring of logic level change of pins programmed as inputs
- Programmable Interrupt Mask Control for input pins that do not require an interrupt when their states change
- Polarity Inversion register allows inversion of the polarity of the I/O pins when read
- Active LOW reset (RESET) input pin resets device to power-up default state
- 3 programmable address pins allowing 8 devices on the same bus
Application Scenarios
The PCA9506DGG can be used in various I2C-bus applications where there is a need to expand the number of I/O ports in use. It can be used to directly drive up to 40 LEDs.
Comparison
Advantages- The PCA9506DGG has a wide operating voltage range of 2.3 V to 5.5 V which makes it suitable for use with a range of devices
- The component has 40 configurable I/O pins that default to inputs at power-up
- It has a controlled edge rate output structure that is totem-pole and outputs capable of sourcing 10 mA and sinking 25 mA
Disadvantages- The PCA9506DGG needs to be connected to a microcontroller via the I2C-bus serial interface for communication which may complicate the design process for some applications.
