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 Latc...
