Product Description
Microchip MCP23017T-E/SS is a 16-channel Input/Output (I/O) expander IC packaged in a 28-pin SSOP surface-mount package. It operates with a clock frequency of up to 10MHz and supports a wide supply voltage range from 1.8V to 5.5V. Designed to expand the number of I/O ports on microcontrollers, this device is ideal for embedded systems requiring additional GPIO pins.
The expander contains multiple 8-bit configuration registers that allow the system master to configure each I/O as input or output. Individual data for these ports is stored in corresponding input or output registers, with polarity inversion capabilities to facilitate various signal requirements. The 16 I/O lines are divided into two 8-bit ports labeled PORTA and PORTB.
The MCP23017T-E/SS supports cascading, allowing up to eight devices on a single I2C bus, permitting extensive system expansion. It provides robust 25mA sink/source current capability on each I/O pin, ideal for driving LEDs and other peripherals directly.
This device operates reliably in a wide temperature range from -40°C to 125°C, making it suitable for industrial, automotive, and commercial applications requiring harsh environment tolerance. Its 28-pin SSOP package is suitable for high-density PCB layouts, and surface mount technology enables automated assembly processes.
16 configurable input/output channels with polarity inversion. Supports I2C interface compatible with 100kHz, 400kHz, and 1.7MHz speeds. Cascadable design allows linking up to eight devices on one I2C bus. Wide operating temperature range: -40°C to 125°C.
Supply voltage range: 1.8V to 5.5V. 25mA current sink/source capability per I/O. Applications include industrial control systems, embedded device expansion, automotive electronics, consumer electronics, and embedded instrumentation.
Its country of origin is Thailand. Explore related electronic components and I/O Expanders at EnvMart for comprehensive solutions to your electronic design needs.
