EL7243
Dual Input, High Speed, Dual Channel
CCD Driver
The EL7243 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 EL7243 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.

NOTE: Intersil Pb-free products employ special Pb-free material sets;
molding compounds/die attach materials and 100% matte tin plate
termination finish, which are RoHS compliant and compatible with
both SnPb and Pb-free soldering operations. Intersil Pb-free products
are MSL classified at Pb-free peak reflow temperatures that meet or
exceed the Pb-free requirements of IPC/JEDEC J STD-020.
