Description

The IH6108 is a CMOS 1-of-8 multiplexer. The part is a plug- in replacement for the DG508A. Three-line decoding is used so that the 8 channels can be controlled by 3 Address inputs; additionally a fourth input is provided for use as a system enable. When the ENABLE input is high (5V), a channel is selected by the three Address inputs, and when low (0V) all channels are off. The 3 Address inputs are TTL and CMOS logic compatible, with a “1” corresponding to any voltage greater than 2.4V.
