For SOH28:
Blank = tubes (Not for New Design - use E)
E = ECOPACK
F = ECOPACK
TR = tape & reel (Not for New Design - use F)
For SOX28:
Blank = ECOPACK
TR = ECOPACK
1. The 28-pin SOIC package (SOH28) requires the SNAPHAT
2. The SOX28 package includes an embedded 32,768 Hz crystal.
Do not place the SNAPHAT
drain the lithium button-cell battery.
