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 VCC as a positive limit and GND as a negative

limit. VCC to GND may not exceed 10 V.

Notes

1. CPD is used to determine the dynamic power dissipation (PD in µW):

PD = CPD × VCC2 × fi + ∑ { (CL + CS) × VCC2 × fo} where:

fi = input frequency in MHz

fo = output frequency in MHz

∑ {(CL + CS) × VCC2 × fo} = sum of outputs

CL = output load capacitance in pF

CS = max. switch capacitance in pF

VCC = supply voltage in V

2. For HC the condition is VI = GND to VCC

For HCT the condition is VI = GND to VCC − 1.5 V
