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.

Provides superior protection from ESD events. These
devices are small and located next to connectors
making them vulnerable on both supply sides.

• Small TQFN and μTQFN package options
Why are level shifters needed?
• Simplifies the interconnection between two ICs
operating at different supply voltages
• Dual-supply level shifters solve the interfacing
problem
Interface components (RS-232/RS-485
transceivers, memory cards, etc.) typically
operate at supply voltages of 3.3V or higher
Shifts logic levels up/down to be compatible
with each of the supply voltages
Gives designers more flexibility in choosing
components for the application
Core components (baseband processors,
μControllers, ASICs, and FPGAs) operate at
lower supply voltages (currently 1.8V)
Lower V logic typically cannot drive higher
