Data Sheet

FN7286.1

Dual Input, High Speed, Dual Channel

CCD Driver

Features

• Logic AND/NAND input

• 3V and 5V Input compatible

• Clocking speeds up to 20MHz

• 20ns Switching/delay time

• 2A Peak drive

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.

• Isolated drains

• Low output impedance

• Low quiescent current

• Wide operating voltage — 4.5V to 16V

• Pb-Free available (RoHS compliant)

(20-PIN THERMAL SOIC)

TOP VIEW

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.

NOTE: Intersil Pb-free products employ special Pb-free material sets;

molding compounds/die attach materials and 100% matte tin plate

termination finish, which are RoHS compliant and compatible with

both SnPb and Pb-free soldering operations. Intersil Pb-free products

are MSL classified at Pb-free peak reflow temperatures that meet or

exceed the Pb-free requirements of IPC/JEDEC J STD-020.

CAUTION: These devices are sensitive to electrostatic discharge; follow proper IC Handling Procedures.
