1. General description
The 74HC4067; 74HCT4067 is a high-speed Si-gate CMOS device and is pin compatible
with the HEF4067B. The device is specified in compliance with JEDEC standard no. 7A.
The 74HC4067; 74HCT4067 is a 16-channel analog multiplexer/demultiplexer 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 74HC4067; 74HCT4067 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 pin E
= LOW, one of the sixteen switches is selected by pins S0 to S3 (low
impedance ON-state). All unselected switches are in the high-impedance OFF-state.
With pin E
= HIGH, all switches are in the high-impedance OFF-state, independent of pins
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.
2. Features and benefits

= 4.5 V
 70  (typical) at V
CC
= 6.0 V
 60  (typical) at V
CC
= 9.0 V
 Typical ‘break before make’ built-in
3. Applications
 Analog multiplexing and demultiplexing
 Digital multiplexing and demultiplexing
 Signal gating
