EL7243C

Dual Input, High Speed, Dual Channel CCD Driver

Features

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 appli-

cable to numerous power MOSFET drive circuits. As with oth-

er 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 imple-

mented by simply ‘‘cross-coupling’’ the 2-channels.

# 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 voltageÐ
