The IDTQS74FCT2245CT is an 8-bit non-inverting transceiver that hasthree-state outputs, ideal for bus-oriented applications. The Transmit/Receive (T/R) input determines the direction of data flow, either from A toB or B to A, and the Output Enable (OE) input enables the selected port foroutput. The QS74FCT2245 has a 25Ω resistor output that is useful fordriving transmission lines and reducing system noise. The QS74FCT2245parts can replace the 245 series to reduce noise in an existing design. Allinputs have clamp diodes for undershoot noise suppression. All outputshave ground bounce suppression. Outputs will not load an active bus whenVcc is removed from the device.
