| EL7243C EL7243C Dual Input High Speed Dual Channel CCD Driver Features Logic AND NAND input 3V and 5V Input compatible Clocking speeds up to 20 MHz 20 ns Switching delay time 2A Peak drive Isolated drains Low output impedance Low quiescent current Wide operating voltage 4 5V - 16V General Description The EL7243C dual input 2-channel driver achieves the same excellent switching performance of the EL7212 family while providing added flexibility The power package makes this part extremely well suited for high frequency and heavy loads as in CCD applications The 2-input logic and configuration is applicable to numerous power MOSFET drive circuits As with other Elantec drivers the EL7243C is excellent for driving large capacitive loads with minimal delay and switching times ``Shoot-thru'' protection and latching circuits can be implemented by simply ``cross-coupling'' the 2-channels Connection Diagram Applications CCD Drivers Short circuit protected switching Under-voltage shut-down circuits Switch-mode power supplies Motor controls Power MOSFET switching Switching capacitive loads Shoot-thru protection Latching drivers 20-Lead Thermal SOL Package EL7243C Ordering Information Part No Temp Range EL7243CM b 40 C to a 85 C Pkg Outline 7243 -
