Quiet Series
with 3-STATE Inputs/Outputs
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 24 mA at
both the A and B ports. The Transmit/Receive (T/R) input
determines the direction of data flow through the bidirec-
tional 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
ogy to guarantee quiet output switching and improve
dynamic threshold performance. FACT Quiet Series
tures GTO
addition to a split ground bus for superior performance.
Ordering Code:
Device also available in Tape and Reel. Specify by appending suffix letter “X” to the ordering code.
