DESCRIPTION:
The IDTQS74FCT2245T is an 8-bit non-inverting transceiver that has
three-state outputs, ideal for bus-oriented applications. The Transmit/
Receive (T/R) input determines the direction of data flow, either from A to
B or B to A, and the Output Enable (OE) input enables the selected port for
output. The QS74FCT2245 has a 25鈩?resistor output that is useful for
driving transmission lines and reducing system noise. The QS74FCT2245
parts can replace the 245 series to reduce noise in an existing design. All
inputs have clamp diodes for undershoot noise suppression. All outputs
have ground bounce suppression. Outputs will not load an active bus when
Vcc is removed from the device.
