It is a part of the 20-SSOP (0.209, 5.30mm Width) package. This packaging has a Tape & Reel (TR)-shape, making it convenient to carry around. A reliable operation requires a temperature that is regulated to -40°C~125°C. It should work as long as you use a 2V~5.5VV power source. Among other things, it contains 20 terminations. 3V is the supply voltage that enables high efficiency. This number is part of the MCP2140A family. To operate, 20 pins are required. 2.2mA supplies are available at the moment. Its IC has the telecom type TELECOM CIRCUIT.
