HCT4067

Limiting values in accordance with the Absolute Maximum System (IEC 134)
Voltages are referenced to GND (ground = 0 V)

The 74HC/HCT4067 are high-speed Si-gate CMOS devices and are pin compatible with the "4067" of the "4000B" series. They are specified in compliance with JEDEC standard no. 7A.The 74HC/HCT4067 are 16-channel analog multiplexers/demultiplexers with four address inputs (S₀ to S₃) , an active LOW enable input (E), sixteen independent inputs/outputs (Y₀ to Y₁₅) and a common input/output (Z). The "4067" contains sixteen bidirectional analog switches, each with one side connected to an independent input/output (Y₀ to Y₁₅) and the other side connected to a common input/output (Z).

With E LOW, one of the sixteen switches is selected (low impedance ON-state) by S₀ to S₃. All 74HC/HCT4067 unselected switches are in the high impedance OFF-state. With E HIGH, all switches are in the high impedance OFF-state, independent of S₀ to S₃. The analog inputs/outputs (Y₀ to Y₁₅, and Z) can swing between V_CC as a positive limit and GND as a negative limit. V_CC to GND may not exceed 10 V.
