MCP23017-E/SP
Microchip TechnologyMCP23017-E/SP is a Microchip 16-bit I2C serial I/O expander in 28-pin SPDIP — for adding sixteen GPIOs over two wires: keypads, LED banks and industrial I/O. Sixteen quasi-bidirectional pins with interrupt-on-change is the selection point: double the PCF8575-class expanders' capability with full configuration registers. Selection advice: the E/SP denotes SPDIP-28 — the hand-solder-friendly variant; for SMT, the SOIC variant is the pick. 1.8–5.5 V operation and up to 1.7 MHz bus suit most designs. Microchip lists this part as In Production. Parameters verified against the Microchip official product page.

MCP23017-E/SP FAQ
What should I check before substituting MCP23017-E/SP with another I2C serial I/O expander?
Match the full ordering code, not the series name: package (SPDIP-28), temperature grade and packing all ride on the suffixes. A same-series code in a different package is a different orderable device, so confirm the substitute against the Microchip Technology datasheet before changing the BOM.
