description  
The ’FCT245T devices contain eight noninverting  
bidirectional buffers with 3-state outputs and are  
intended for bus-oriented applications.  
The transmit/receive (T/R) input determines the direction of data flow through these bidirectional transceivers.  
Transmit (active high) enables data from A ports to B ports. The output enable (OE), when high, disables both  
the A and B ports by putting them in the high-impedance state.  
These devices are fully specified for partial-power-down applications using I . The I circuitry disables the  
off  
off  
outputs, preventing damaging current backflow through the device when it is powered down.
