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 Ioff. The Ioff circuitry disables the outputs, preventing damaging current backflow through the device when it is powered down.
●Function, Pinout, and Drive Compatible With FCT and F Logic
●Reduced VOH(Typically = 3.3 V) Versions of Equivalent FCT Functions
●Edge-Rate Control Circuitry for Significantly Improved Noise Characteristics
●Ioff Supports Partial-Power-Down Mode Operation
●ESD Protection Exceeds JESD 22
