74ACQ245 • 74ACTQ245  
Quiet Series¥ Octal Bidirectional Transceiver  
with 3-STATE Inputs/Outputs  
General Description  
Features  
■ ICC and IOZ 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 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.  
■ 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 24 mA  
■ Faster prop delays than the standard ACT245  
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.
