MCP23016 _ BDTIC a Leading Distributor in China

MCP23016

The MCP23016 is not recommended for new designs. Please consider using the or instead.

The MCP23016 device provides 16-bit, general purpose, parallel I/O expansion for I²C™Compatible bus applications. It includes high-current drive capability, low supply current and individual I/O configuration. I/O expanders provide a simple solution when additional I/Os are needed for ACPI, power switches, sensors, push buttons, LEDs and so on.

Features

16-bit I/O port expander with interrupt
3 hardware address pins allow user to use up to 8 of these devices on the same I2C/SMBus
25mA source/sink capability per I/O
I2C and SMBus compatible interface (0 to 400kHz clock frequency)
16 programmable bi-directional I/Os compatible with most processors
Outputs can directly drive LEDs (Source and sink current 25mA)
Polarity inversion register to configure the polarity of the input port data
Internal power on reset (POR)
Open-drain interrupt output activated when input changes state
Low supply current
Specified over Industrial temperature range -40°C to +85°C
