Data sheet acquired from Harris Semiconductor
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.
