EL7104
High Speed, Single Channel, Power
MOSFET Driver
The EL7104 is a matched driver IC that improves the
operation of the industry-standard TC-4420/29 clock drivers.
The Elantec version is a very high speed driver capable of
delivering peak currents of 1A into highly capacitive loads.
The high speed performance is achieved by means of a
proprietary "Turbo-Driver" circuit that speeds up input stages
by tapping the wider voltage swing at the output. Improved
speed and drive capability are enhanced by matched rise
and fall delay times. These matched delays maintain the
integrity of input-to-output pulse-widths to reduce timing
errors and clock skew problems. This improved performance
is accompanied by a 10-fold reduction in supply currents
over bipolar drivers, yet without the delay time problems
commonly associated with CMOS drivers.
The EL7104 is available in 8-pin SO and 8-pin PDIP
packages and is specified for operation over the full -40C to
+85C temperature range.

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.
