Notes:
1. Stresses above the ratings listed below can cause permanent damage to the IDT2308B. These ratings, which are standard
values for IDT commercially rated parts, are stress ratings only. Functional operation of the device at these or any other
conditions above those indicated in the operational sections of the specifications is not implied. Exposure to absolute
maximum rating conditions for extended periods can affect product reliability. Electrical parameters are guaranteed only over
the recommended operating temperature range.
2. The input and output negative-voltage ratings may be exceeded if the input and output clamp-current ratings are observed.
3. The maximum package power dissipation is calculated using a junction temperature of 150°C and a board trace length of 750
mils.
