The exposed pad on the µMAX package provides a low
thermal resistance for heat dissipation. Solder the
exposed pad to a ground plane for best thermal perfor-
mance. Do not route traces under these packages. For
dual-supply operation, the exposed pad (EP) can be
electrically connected to the negative supply or it can
be left unconnected.
PROCESS: BiCMOS
