74ACQ245, 74ACTQ245 Rev. 1.5.1
January 2008
74ACQ245, 74ACTQ245
Quiet Series™ Octal Bidirectional Transceiver with
3-STATE Inputs/Outputs
Features
ICC and IOZ reduced by 50%
Guaranteed simultaneous switching noise level and
dynamic threshold performance
Guaranteed pin-to-pin skew AC performance
Improved latch-up immunity
3-STATE outputs drive bus lines or buffer memory
address registers
Outputs source/sink 24mA
Faster prop delays than the standard ACT245
General Description
The ACQ/ACTQ245 contains eight non-inverting bidirec-
tional buffers with 3-STATE outputs and is intended for
bus-oriented applications. Current sinking capability is
24mA at both the A and B ports. The Transmit/Receive
(T/R) input determines the direction of data flow through
the bidirectional transceiver. Transmit (active-HIGH)
enables data from A Ports to B Ports; Receive (active-
LOW) enables data from B Ports to A Ports. The Output
Enable input, when HIGH, disables both A and B ports
by placing them in a HIGH Z condition.
The
ACQ/ACTQ
utilizes
Fairchild
Quiet
Series™
technology to guarantee quiet output switching and
improve dynamic threshold performance. FACT Quiet
Series™ features GTO™ output control and undershoot
corrector in addition to a split ground bus for superior
performance.
Ordering Information
Device also available in Tape and Reel. Specify by appending suffix letter “X” to the ordering number.
All packages are lead free per JEDEC: J-STD-020B standard.
