| EL7104C EL7114C EL7104C EL7114C High Speed Single Channel Power MOSFET Drivers Features 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 General Description 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 Applications Clock line drivers CCD Drivers Ultra-sound transducer drivers Power MOSFET drivers Switch mode power supplies Resonant charging Cascoded drivers Connection Diagrams EL7104C Non-Inverting Driver Ordering Information Part No Temp Range Pkg Outline 7104 -
