General description
The 74HC4051; 74HCT4051 is a single-pole octal-throw analog switch (SP8T) suitable
for use in analog or digital 8:1 multiplexer/demultiplexer applications. The switch features
three digital select inputs (S0, S1 and S2), eight independent inputs/outputs (Yn), a
common input/output (Z) and a digital enable input (E). When E is HIGH, the switches
are turned off. Inputs include clamp diodes. This enables the use of current limiting
resistors to interface inputs to voltages in excess of V
CC
.

[1] To avoid drawing V
CC
current out of terminal Z, when switch current flows into terminals Yn, the voltage drop across the bidirectional switch must not
exceed 0.4 V. If the switch current flows into terminal Z, no V
CC
current will flow out of terminals Yn, and in this case there is no limit for the voltage drop
across the switch, but the voltages at Yn and Z may not exceed V
CC
or V
EE
.
[2] For SO16 packages: above 70 °C the value of P
tot
derates linearly with 8 mW/K.
For SSOP16 and TSSOP16 packages: above 60 °C the value of P
tot
derates linearly with 5.5 mW/K.
For DHVQFN16 packages: above 60 °C the value of P
tot
derates linearly with 4.5 mW/K.
