74HC4851; 74HCT4851
8-channel analog MUX/DEMUX with injection-current effect control
7. Functional description
[1] H = HIGH voltage level;
L = LOW voltage level;
X = don’t care.
8. Limiting values
[1] The minimum and maximum input voltage rating may be exceeded if the input clamping current rating is observed.
[2] The minimum and maximum switch voltage rating may be exceeded if the switch clamping current rating is observed.
