Legacy Part Numbers: `S' Denoted Symmetry of 45%/55% at 50% of VCC. This is now the standard Duty Cycle and is no longer needed inthe part number. We will still support part numbers with the `S'. For example: SM7745DX and SM7745DSX describe the same specifications and can be used interchangeably by the customer.

Recommend connecting appropriate power supply bypass capacitors as close as possible.
Layout and application information
For Optimum Jitter Performance, Pletronics recommends: * a ground plane under the device * no large transient signals (both current and voltage) should be routed under the device * do not layout near a large magnetic field such as a high frequency switching power supply * do not place near piezoelectric buzzers or mechanical fans.
