Product Summary

The CY74FCT245TQCT is an 8-bit transceiver with 3-state outputs. The device contains eight noninverting bidirectional buffers with 3-state outputs and are intended for bus-oriented applications. The CY74FCT245TQCT 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.
