74ACQ245, 74ACTQ245
Quiet Series™ Octal Bidirectional Transceiver with
3-STATE Inputs/Outputs
Features
General Description
■ I and I reduced by 50%
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.

■ 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
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.

Absolute Maximum Ratings
Stresses exceeding the absolute maximum ratings may damage the device. The device may not function or be
operable above the recommended operating conditions and stressing the parts to these levels is not recommended.
In addition, extended exposure to stresses above the recommended operating conditions may affect device reliability.
The absolute maximum ratings are stress ratings only.

■ Determine the quiet output pin that demonstrates the
greatest noise levels. The worst case pin will usually
be the furthest from the ground pin. Monitor the output

standard SMB type connector on the test fixture. Do
not use an active FET probe.

2. Deskew the HFS generator so that no two channels

requires that the oscilloscope be deskewed first. It is
important to deskew the HFS generator channels
