Quiet Series¥ Octal Bidirectional Transceiver
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¥ technol-
ogy to guarantee quiet output switching and improve
dynamic threshold performance. FACT Quiet Series¥ fea-
tures GTO¥ output control and undershoot corrector in
addition to a split ground bus for superior performance.
Features
s ICC and IOZ reduced by 50%
s Guaranteed simultaneous switching noise level and
dynamic threshold performance
s Guaranteed pin-to-pin skew AC performance
s Improved latch-up immunity
s 3-STATE outputs drive bus lines or buffer memory
address registers
s Outputs source/sink 24 mA
s Faster prop delays than the standard ACT245
