General description

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-channel analog 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 E LOW, one of the two switches is selected (low-impedance ON-state) by S1 to S3.

With E HIGH, all switches are in the high-impedance OFF-state, independent of S1 to S3.

VCC and GND are the supply voltage pins for the digital control inputs (S1 to S3 and E).

The VCC to GND ranges are 2.0 V to 10.0 V for 74HC4053 and 4.5 V to 5.5 V for

74HCT4053. The analog inputs/outputs (nY0 and nY1, and nZ) can swing between VCC

as a positive limit and VEE as a negative limit. VCC - VEE may not exceed 10.0 V.

For operation as a digital multiplexer/demultiplexer, VEE is connected to GND (typically

ground).
