74HCT4053

Note to ratings
To avoid drawing V_CC current out of terminals nZ, when switch current flows in terminals nY_n, the voltage drop across the bidirectional switch must not exceed 0.4 V. If the switch current flows into terminals nZ, no V_CC current will flow out of terminals nY_n. In this case there is no limit for the voltage drop across the switch, but the voltages at nY_n and nZ may not exceed V_CC or V_EE.

The 74HCT4053 is high-speed Si-gate CMOS devices and are pin compatible with the "4053" of the "4000B" series. They are specified in compliance with JEDEC standard no. 7A.

The 74HCT4053 is triple 2-channel analog multiplexers/demultiplexers 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 (S₁ to S₃).

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.

V_CC and GND of the 74HCT4053 are the supply voltage pins for the digital control inputs (S₁, to S₃, and E). The V_CC to GND ranges are 2.0 to 10.0 V for HC and 4.5 to 5.5 V for HCT. The analog inputs/outputs (nY₀ and nY₁, and nZ) can swing between V_CC as a positive limit and V_EE as a negative limit. V_CC - V_EE may not exceed 10.0 V.

For operation of the 74HCT4053 as a digital multiplexer/demultiplexer, V_EE is connected to GND (typically ground).
