EL7243
Data Sheet May 13, 2005 FN7286.1
Dual Input, High Speed, Dual Channel CCD Driver
The EL7243 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 EL7243 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.
Features
* Logic AND/NAND input * 3V and 5V Input compatible * Clocking speeds up to 20MHz * 20ns Switching/delay time * 2A Peak drive * Isolated drains * Low output impedance * Low quiescent current * Wide operating voltage -- 4.5V to 16V * Pb-Free available (RoHS compliant)

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
Note 1: Pins 4-7 and 14-17 are electrically connected. Note 2: Output pins must be tied together.
