74VHC153
Dual 4-Input Multiplexer
General Description
The VHC153 is an advanced high-speed CMOS device
fabricated with silicon gate CMOS technology. It achieves
the high-speed operation similar to equivalent Bipolar
Schottky TTL while maintaining the CMOS low power dissipation. The VHC153 i s a high-speed Dual 4-Input Multiplexer with common select inputs and individual enable
inputs for each section. It can select two lines of d ata fro m
four sources. The t wo buffered outpu ts pre sen t data in t he
true (non-inverted) form. In addition to multipl exer operation, the VHC153 can act as a function generator a nd generate any two functions of three variables. An input
protection circuit insure s that 0V to 7V can be applied to
the input pins without regard to the suppl y voltage. This
device can be used to in terface 5V to 3V sys tems an d two
supply systems such as battery backup. This circuit prevents device destruction due to mismatched supply and
input voltages.

74VHC153
Functional Description
The VHC153 is a dual 4-input multiplexer. It can select two
bits of data from up to four sources under the control of the
common Select inputs (S
0
, S1). The two 4-input multiplexer
circuits have individ ua l acti ve -LO W En ab les (E
a
, Eb) which
can be used to strobe the outputs independently. When the
Enables (E
a
, Eb) are HIGH, the cor resp on ding ou tpu t s ( Za,
Z
b
) are forced LOW. The VHC153 is the lo gic implementa-
tion of a 2-pole, 4-position switch, where the position of the
switch is determined by the logic levels supplied to the
Select inputs. The logic equations for the outputs are
shown below.

Absolute Maximum Ratings(Note 1) Recommended Operating
Conditions
(Note 2)
Note 1: Absolute maximum ratings are those values beyon d which the
device may be damaged or have its us eful life impaired. The d atabook
specifications should be met, without exception, to ensure that the system
design is reliable over its power supply, temperature, and output/input loading variables. F airchild does not recommend oper ation outside datab ook
specifications.
Note 2: Unused inputs must be held HIGH or LOW. They may not float.
