devices also.
• S-Pkg is Solder pad compatible with the Epson
SG615 and SG8002J and many other 9x14mm
plastic J lead packages.
• FR4 base with an SM77D series oscillator.
• Capable of driving up to 30pF capacitive loads
• Tape and Reel or cut tape packaging available.

Legacy Part Numbers:
‘S’
Denoted Symmetry of 45%/55% at 50% of V
CC
. This is now the standard Duty Cycle and is no longer needed in
the part number. We will still support part numbers with the ‘S’. For example SM7645DY and SM7645DS
describe the same specifications and can be used interchangeably by the customer.
-30
Denoted Output Load other than the standard 15 pF. Data sheets now reflect the specifications at all available
loads so this load designation is no longer needed. We’ll still support part numbers with this load designation.
