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.
