Description
The ’HC4351, CD74HCT4351, and CD74HC4352 are
digitally controlled analog switches which utilize silicon-gate
CMOS technology to achieve operating speeds similar to
LSTTL with the low power consumption of standard CMOS
integrated circuits.
These analog multiplexers/demultiplexers are, in essence,
the HC/HCT4015 and HC4052 preceded by address latches
that are controlled by an active low Latch Enable input (LE).
Two Enable inputs, one active low (E1), and the other active
high (E2) are provided allowing enabling with either input
voltage level.
