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
