The EL7242C/EL7252C dual input, 2-channel drivers achieve
the same excellent switching performance of the EL7212 family
while providing added flexibility. The 2-input logic and configuration is applicable to numerous power MOSFET drive circuits.
As with other Elantec drivers, the EL7242C/EL7252C are excellent for driving large capacitive loads with minimal delay
and switching times. ‘‘Shoot-thru’’ protection and latching circuits can be implemented by simply ‘‘cross-coupling’’ the 2channels.
Logic AND/NAND input

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 TJ e TC e TA.
