Introducing the Mighty MCP23017-E/SP I2C 16 Digital IO Expansion IC - A Lonely Binary Marvel!

Are you tired of your microcontroller feeling lonely with not enough pins to play with? Fear not, for Lonely Binary comes to the rescue with our MCP23017-E/SP I2C 16 Digital IO Expansion IC! It's the ultimate wingman for your microcontroller, adding an extra 16 pins to its entourage and taking its I/O game to a whole new level of awesomeness!

Say hello to seamless pin expansion, courtesy of this clever MCP23017. This little genius uses just two i2c pins, which means it can totally hang out and share its I2C goodness with other devices. In return, you'll get not one, not five, but a whopping 16 versatile general-purpose pins to play around with!

Feeling the need for speed? Not a problem! This chip works like a charm with voltage levels ranging from 2.7V to 5.5V, making it a perfect match for any 3.3V or 5V setup. So, whether your microcontroller loves the thrill of 3.3V or the adrenaline rush of 5V, this expansion IC is always up for an adventure!

Lonely Binary's MCP23017-E/SP can sink and source up to 20mA from any of the I/O pins, making it a true hero for handling LEDs and other nifty components. But wait, there's more! If your gadgets crave even more power, you can team this IC up with a high-power MOSFET and watch the sparks fly!

Who needs a complicated setup? Not you! This DIP-packaged marvel is ready to dive right into any breadboard or perfboard, making it the ultimate plug-and-play companion for all your projects.

Now, let's talk about partying with pals! By setting the i2c address with ADDR0-2 pins, you can have up to 8 unique addresses. That's right, up to 8 of these fantastic chips can be friends on a single i2c bus, giving you a jaw-dropping 128 I/O pins to take your microcontroller's social life to the next level!

So there you have it - the Lonely Binary MCP23017-E/SP I2C 16 Digital IO Expansion IC, your microcontroller's new BFF (Best Friend Forever!). Let the pin party begin and watch your projects come to life like never before!
