Product specification
Dual 4-channel analog
multiplexer/demultiplexer with latch
74HC/HCT4352
RATINGS
Limiting values in accordance with the Absolute Maximum System (IEC 134)
Voltages are referenced to V
EE
= GND (ground = 0 V)
Note
1.
To avoid drawing V
CC
current out of terminals nZ, when switch current flows in terminals nY
n
, the voltage drop across
the bidirectional switch must not exceed 0.4 V. If the switch current flows into terminals nZ, no V
CC
current will flow
out of terminals nY
n
. In this case there is no limit for the voltage drop across the switch, but the voltages at nY
n
and
nZ may not exceed V
CC
or V

.
