General Description
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 configu-
ration is applicable to numerous power MOSFET drive circuits
As with other Elantec drivers the EL7242C EL7252C are ex-
cellent for driving large capacitive loads with minimal delay
and switching times ``Shoot-thru'' protection and latching cir-
cuits can be implemented by simply ``cross-coupling'' the 2-
channels
