74ACTQ245
Quiet Series Octal Bidirectional Transceiver with 3-STATE Outputs

General Description

The ACQ/ACTQ245 contains eight non-inverting bidirectional 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 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.

Features

I_CC and I_OZ 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 24 mA
Faster prop delays than the standard ACT245
