Product Summary
?? With three state (1, open, 0) setting function, especially suitable for encoding/decoding
of tri-state encoder/decoder integrated circuit to obtain more security codes than
traditional two-state (1,0) operation. For instance, 9 bits with tri-state gets 19,683 (39)
codes, while two-state has 512 (29) codes, gains 38 times more codes with a ECE
