General Description
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 appli-
cable to numerous power MOSFET drive circuits As with oth-
er 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 imple-
mented by simply ``cross-coupling'' the 2-channels
