Intersil Interface Products www.intersil.com/interface Best-in-Class ESD Protected Level Translators Connecting the level shifter to the two-system supplies allows it to shift voltages up/down for compatibility in mixed supply systems. ±15kV ESD Protection (HBM and IEC61000-4-2 Air Gap) on Both the VCC and VL Sides Provides superior protection from ESD events. These devices are small and located next to connectors making them vulnerable on both supply sides.
