HIGH-SPEED CMOS SYNCHROSWITCH DUAL 4:1 MUX/DEMUX
INDUSTRIALTEMPERATURERANGE
FUNCTION TABLE(1)
NOTES:
1. H = HIGH Voltage Level
L = LOW Voltage Level
X = Don’t Care
Z = High-Impedence
↑ = LOW-to-HIGH Transition
2. Mux switches are turned off and the terminators (last value latches) hold the previous data state. The port connections can be changed by the SEL input.
3. The contents of the “Mux select register” are unchanged and the previous Mux connection is unchanged. The output (Mux port) data state will depend on the present data
state of the input (Demux port).
4. The contents of the “Mux select register” are unchanged and the last value latch holds the previous data state.
