HEF4051B
8-channel analog multiplexer/demultiplexer
7. Functional description
7.1 Function table
[1] H = HIGH voltage level; L = LOW voltage level; X = don’t care.
8. Limiting values
[1] To avoid drawing V
DD
current out of terminal Z, when switch current flows into terminals Y, the voltage drop across the bidirectional
switch must not exceed 0.4 V. If the switch current flows into terminal Z, no V
DD
current will flow out of terminals Y, and in this case there
is no limit for the voltage drop across the switch, but the voltages at Y and Z may not exceed V
DD
or V
EE
.
[2] For DIP16 package: P
tot
derates linearly with 12 mW/K above 70 C.
For SO16 package: P
tot
derates linearly with 8 mW/K above 70 C.
For SSOP16 and TSSOP16 packages: P
tot
derates linearly with 5.5 mW/K above 60 C.
