General Description
The EL7501 provides a low cost solution to many high side
drive applications The EL7501 is DC coupled so there are no
start up problems associated with AC coupled schemes The
EL7501 is driven by user supplied complementary signals

Important Note
All parameters having Min Max specifications are guaranteed The Test Level column indicates the specific device testing actually
performed during production and Quality inspection Elantec performs most electrical tests using modern high-speed automatic test
equipment specifically the LTX77 Series system Unless otherwise noted all tests are pulsed tests therefore T
