General Description
The EL7104C and EL7114C ICs are matched driver ICs that improve
the operation of the industry-standard TC-4420/29 clock drivers. The
Elantec versions are very high speed drivers 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.
