EL7182C
EL7182C
2-Phase High Speed CCD Driver
Features
3V and 5V Input compatible Clocking speeds up to 10 MHz Reduced clock skew 20 ns Switching delay time 2A Peak drive Low quiescent current Wide operating voltage 4 5V - 16V
General Description
The EL7182C is extremely well suited for driving CCD's especially where high contrast imaging is desirable The 16V supply rating is attractive for higher voltage CCD applications as in color fax machines The input is TTL and 3V compatible The low quiescent current requirement is advantageous in portable battery powered systems The EL7182 is available in 8-pin P-DIP and 8-lead SO packages
