#
#
#
The EL7243C dual input, 2-channel driver achieves the same
excellent switching performance of the EL7212 family while
providing added flexibility. The power package makes this part
extremely well suited for high frequency and heavy loads as in
CCD applications. The 2-input logic and configuration is applicable to numerous power MOSFET drive circuits. As with other Elantec drivers, the EL7243C is 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 2-channels.

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.
