EL7242, EL7252

Data Sheet February 15, 2008

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.

*Add “-T7” or “-T13” suffix for tape and reel. Please refer to TB347

for details on reel specifications.
**Pb-free PDIPs can be used for through hole wave solder

processing only. They are not intended for use in Reflow solder
processing applications.
NOTE: These Intersil Pb-free plastic packaged products employ
special Pb-free material sets; molding compounds/die attach
materials and 100% matte tin plate PLUS ANNEAL - e3 termination
finish, which is 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.
