EL7242, EL7252
Dual Input, High Speed, Dual Channel
Power MOSFET Driver
The EL7242/EL7252 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
EL7242/EL7252 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 2-channels.
Features
Logic AND/NAND input
3V and 5V Input compatible

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.
