74AC153 74ACT153 Dual 4-Input Multiplexer
General Description
The AC/ACT153 is a high- speed dual 4-input multiplexer with common select inpu ts and in dividu al enab le inp uts for each section. It can select two lines of data from four sources. The two buffered outpu ts pre sent d ata in t he tr ue (non-inverted) form. In addition to multiplexer operation, the AC/ACT153 can act as a function generator and gener­ate any two functions of three variables.
Features
ICC reduced by 50%
Outputs source/sink 24 mA
ACT153 has TTL-compatible inputs

Functional Description
The AC/ACT153 is a dua l 4-input mul tiplexer. 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 multi-
plexer circ ui ts ha ve i n di vi d ua l ac t iv e- L OW E n ab les ( E
a
, Eb)
which can be used to strobe the outputs independently. When the Enables ( E
a
, Eb) are HIGH, the corre sponding
outputs Z
a
, Zb) are forced LOW. The AC/ACT153 is the
logic implementatio n of a 2-pole, 4-positi on switch, where the position of the swit ch is determined b y the logic level s supplied to the Select i nputs. The logic equations f or the outputs are shown below.

Absolute Maximum Ratings(Note 1) Recommended Operating
Conditions
Note 1: Absolute max imum ratings are those values beyond w hich damage
to the device may occu r. The databook spe cificatio ns shou ld be met, wit h­out exception, to ensure that the system de sign is relia ble over its p ower supply, temperature, and output/input loading variables. Fairchild does not recommend operation of FACT circuits outside databook specif ic at ions.
