To Control MC3164/MC3264
MC3164 is a 64-channel single-ended multiplexer (MUX-64 for short). MC3264 is a
64-channel single-ended reed multiplexer (REED-MUX-64 for short) and can provide
relatively faster switching speed. MC3164/MC3264 is divided into two banks of 32
single-ended channels (HI only, the 32 channels has a common LO terminal) each
and cannot be used for 4-wire connection. MC3164/MC3264 is used with the external
terminal block (M3TB64) which has a built-in thermocouple reference junction.
