The MTCH650 is a line driver device, with 21 level shifters available.  MTCH650 require only a 3-wire serial interface, latch enable (LE), and 2 capacitors.  

While the MTCH650 and MTCH652 are very similar, the MTCH650 does not include a built-in boost circuit.  The MTCH650 will require an external boost voltage device, such as the MCP16301.
