I
PLL620-06 only: Drive Select Input. This pin has an internal
pull-up that will default DRIVSEL to ‘1’ when not connect to
GND. CMOS output of PLL620-06 will be high drive CMOS
when DRIVSEL is set to ‘0’, and will be standard CMOS
otherwise. The pin remains ‘Do Not Connect (DNC)’ for
PLL620-05/07/08/09.

* Note: PLL620-06 only available in 3x3mm QFN, PLL620-07 only available in TSSOP.
** Note: DRIVSEL on pin 12 on PLL620-06 only. The pin remains ‘Do Not Connect (DNC)’ for PLL620-05/07/08/09.
