Its DIP-28 package is breadboard-friendly, making it ideal for professional embedded design, automation, and industrial applications requiring efficient, low-power parallel I/O expansion. ## Description The MCP23017 device family provides 16-bit, general purpose parallel I/O expansion for I2C bus applications. The MCP23017-E/SP consists of multiple 8 bit configuration registers for input, output and polarity selection. The system master can enable the I/Os as either inputs or outputs by writing the I/O configuration bits (IODIRA/B). The data for each input or output is kept in the corresponding input or output register. The polarity of the Input Port register can be inverted with the Polarity Inversion register. All registers can be read by the system master. The 16-bit I/O port functionally consists of two 8-bit ports (PORTA and PORTB). The MCP23017 can be configured to operate in the 8-bit or 16-bit modes via IOCON.BANK. There are two interrupt pins, INTA and INTB, that can be associated with their respective ports, or can be logically OR’ed together so that both pins will activate if either port causes an interrupt. ## Features - 16 bit remote bidirectional I/O port, Configurable interrupt output pins, INTA and INTB can be configured to operate independently or together - High speed I2C interface: 100 kHz, 400 kHz, 1.7 MHz, Configurable interrupt source, Polarity Inversion register to configure the polarity of the input port data - Three hardware address pins to allow up to eight devices on the bus - External Reset input, Low standby current: 1ΞΌA max. - Example Applications: Automation & Process Control, Automotive, Clock & Timing, Consumer Electronics, Defence, Military & Aerospace, Embedded Design & Development, LED Lighting, Industrial, Motor Drive & Control ## Technical Specifications | Specification | Value | |---------------|-------| | Customer Reviews | 5.0 out of 5 stars 6 Reviews | ## Images ![MCP23017-E/SP MCP23017 16-Bit I/O Expander with Serial Interface 1.7 MHz I2C Breadboard-Friendly IC DIP-28 (1 Piece) - Image 1](https://m.media-amazon.com/images/I/71XZZse4sCL.jpg) ![MCP23017-E/SP MCP23017 16-Bit I/O Expander with Serial Interface 1.7 MHz I2C Breadboard-Friendly IC DIP-28 (1 Piece) - Image 2](https://m.media-amazon.com/images/I/81UoRm9vw0L.jpg) ![MCP23017-E/SP MCP23017 16-Bit I/O Expander with Serial Interface 1.7 MHz I2C Breadboard-Friendly IC DIP-28 (1 Piece) - Image 3](https://m.media-amazon.com/images/I/71QKRtLiscL.jpg) ![MCP23017-E/SP MCP23017 16-Bit I/O Expander with Serial Interface 1.7 MHz I2C Breadboard-Friendly IC DIP-28 (1 Piece) - Image 4](https://m.media-amazon.com/images/I/81YRijVHeVL.jpg) ![MCP23017-E/SP MCP23017 16-Bit I/O Expander with Serial Interface 1.7 MHz I2C Breadboard-Friendly IC DIP-28 (1 Piece) - Image 5](https://m.media-amazon.com/images/I/81iTiClhNqL.jpg) ## Frequently Bought Together - Juried Engineering MCP23017-E/SP MCP23017 16-Bit I/O Expander with Serial Interface 1.7 MHz I2C Breadboard-Friendly IC DIP-28 (1 Piece) - KOOBOOK 5Pcs DRV8833 Motor Drive Module 1.5A Dual H Bridge DC Gear Motor Driver Controller Board - 20PCS 2.54mm Breakaway PCB Board 40Pin Male and Female Header Connector for Arduino Shield --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.ae/products/245772308-mcp23017-e-sp-mcp23017-16-bit-i-o-expander-serial](https://www.desertcart.ae/products/245772308-mcp23017-e-sp-mcp23017-16-bit-i-o-expander-serial) --- *Product available on Desertcart United Arab Emirates* *Store origin: AE* *Last updated: 2026-08-24*
