Part number : HC4053, 74HC4053, 74HCT4053
Functions : Triple 2-channel analog multiplexer/demultiplexer
The 74HC4053; 74HCT4053 is a high-speed Si-gate CMOS device and is pin compatible
with the HEF4053B. It is specified in compliance with JEDEC standard no. 7A.
The 74HC4053; 74HCT4053 is triple 2-channelanalog multiplexer/demultiplexer with a common enable input (E). Each multiplexer/demultiplexer has two independent inputs/outputs (nY0 and nY1), a common input/output (nZ) and three digital select inputs (Sn). With ELOW, one of the two switches is selected (low-impedance ON-state) by S1 to S3. With EHIGH, all switches are in the high-impedance OFF-state, independent of S1 to S3.
