74ACTQ153
Quiet Series Dual 4-Input Multiplexer
General Description
The ACTQ153 is a high-speed dual 4-input multiplexer with
common select inputs and individual enable inputs for each
section. It can select two lines of data from four sources.
The two buffered outputs present data in the true (non-
inverted) form. In addition to multiplexer operation, the
ACTQ153 can act as a function generator and generate
any two functions of three variables.
Features
a73 Outputs source/sink 24 mA
a73 ACTQ153 has TTL-compatible inputs
a73 Guaranteed simultaneous switching noise level and
dynamic threshold performance
a73 Guaranteed pin-to-pin skew AC performance
a73 Improved latch-up immunity

Ordering Code:
Device also available in Tape and Reel. Specify by appending suffix letter “X” to the ordering code.
