Maxim Integrated
General Description
The MAX3372E–MAX3379E and MAX3390E–MAX3393E ±15kV ESD-protected level translators provide the level
shifting necessary to allow data transfer in a multivoltage system. Externally applied voltages, VCCand VL, set the
logic levels on either side of the device. A low-voltage logic signal present on the VLside of the device appears
as a high-voltage logic signal on the VCCside of the device, and vice-versa.
