Product specification
8-channel analog multiplexer/demultiplexer
74HC/HCT4051
RATINGS
Limiting values in accordance with the Absolute Maximum System (IEC 134)
Voltages are referenced to V
EE
= GND (ground = 0 V)
Note to ratings
1.
To avoid drawing V
CC
current out of terminal Z, when switch current flows in terminals Y
n
, 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 Y
n
. In this case there is no limit for the voltage drop across the switch, but the voltages at Y
n
and Z may
not exceed V
CC
or V
EE
.
