High Speed, Single Channel, Power MOSFET Drivers Features General Description # Industry standard driver replacement # Improved response times # Matched rise and fall times # Reduced clock skew # Low output impedance # Low input capacitance # High noise immunity # Improved clocking rate # Low supply current # Wide operating range # Separate drain connections The EL7104C/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 4A 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 devices.
