Product specication
8-channel analog multiplexer/demultiplexer
with latch
74HC/HCT4351
RATINGS
Limiting values in accordance with the Absolute Maximum System (IEC 134)
Voltages are referenced to VEE = GND (ground = 0 V)
Note to ratings
1. To avoid drawing VCC current out of terminal Z, when switch current flows in terminals Yn, the voltage drop across
the bidirectional switch must not exceed 0.4 V. If the switch current flows into terminal Z, no VCC current will flow out
of terminals Yn. In this case there is no limit for the voltage drop across the switch, but the voltages at Yn and Z may
not exceed VCC or VEE.
