CY74FCT2245TSOCT

8位收发器 8-Bit Transceiver

The CY74FCT2245T contains eight noninverting, bidirectional buffers with 3-state outputs intended for bus-oriented applications. On-chip termination resistors at the outputs reduce system noise caused by reflections. For this reason, the CY74FCT2245T can replace the CY74FCT245T in an existing design. The CY74FCT2245T current-sinking capability is 12 mA at 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 OE\\\\ input, when high, disables both the A and B ports by putting them in the high-impedance state.

This device is 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. View datasheet View product folder
