hi
I have a project which use a 4x3 keyapd with keys position similar to that of an odinary teliphone. I have Purchase a MM74C922N keypad encoer. the problem is that i found out that it is a 16 bit keypad encoder intended for a 4x4 keypad..
im looking for a IC keypad encoder which is applicable to the 4x3 keypad which i intended to use.
do any one knows any part number for a common keypad encoder IC that i can use for my project.
tenx.
