Description

The

Harris

CD74HC4351,

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.
