GENERAL DESCRIPTION
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 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.

Notes
1. C_PD is used to determine the dynamic power dissipation (P_D in µW):
P_D = C_PD × V_CC2 × f_i + ∑ { (C_L + C_S) × V_CC2 × f_o} where:
f_i = input frequency in MHz
f_o = output frequency in MHz
∑ {(C_L + C_S) × V_CC2 × f_o} = sum of outputs
C_L = output load capacitance in pF
C_S = max. switch capacitance in pF
V_CC = supply voltage in V
2. For HC the condition is V_I = GND to V_CC
For HCT the condition is V_I = GND to V_CC − 1.5 V
