General Description
The EL7202C/EL7212C/EL7222C ICs are matched dual-driv-
ers ICs that improve the operation of the industry standard
DS0026 clock drivers. The Elantec Versions are very high speed
drivers capable of delivering peak currents of 2.0 amps 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 out-
put. Improved speed and drive capability are enhanced by
matched rise and fall delay times. These matched delays main-
tain the integrity of input-to-output pulse-widths to reduce tim-
ing 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 devices. Dynamic switching losses are
minimized with non-overlapped drive techniques.
