• Internal Diode in Series with V+ for Fault Protection
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.
