Description
The IH6208 is a CMOS 2 of 8 multiplexer. The part is a
plug-in replacement for the DG509A. Two-line binary
decoding is used so that the 8 channels can be controlled in
pairs by the binary inputs; additionally a third input is
provided for use as a system enable. When the ENABLE
input is high (5V), the channels are sequenced by the 2 line
binary inputs, and when low (0V) all channels are off. The 2
Address inputs arecontrolled by TTL logic or CMOS logic
elements with a “0” corresponding to any voltage less than
0.8V and a “1” corresponding to any voltage greater than
2.4V. Note that the ENABLE input must be taken to 5V to
enable the system, and less than 0.8V to disable the system.
