Best-in-Class ESD Protected
Level Translators
The ISL3034E/35E/36E run at 100Mbps in 4/6 channel configurations.
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 V_CC and V_L Sides
Provides superior protection from ESD events. These
devices are small and located next to connectors
making them vulnerable on both supply sides.
Auto-direction Sensing
Eliminates direction control logic pins and
associated software control.
100Mbps Data Rate
Supports high-speed SD memory cards.
