EL7182CSb40§Ctoa85§C 8-Pin SOMDP0027
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.
