EL7104
Data Sheet December 3, 2002 FN7113
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.
