The 74CVXH245 is an advanced performance non-inverting 8-bit transceiver. It is designed for very high-speed very low-power operation in 1.8 V 2.5 V or 3.3 V systems. The VCXH245 is designed as a byte control. The Transmit/Receive (T/Rn) inputs determine the direction of data flow through the bi-directional transceiver. Transmit (active-HIGH) enables data from A ports to B ports; Receive (active- LOW) enables data from B to A ports. The output enable input (OE) when HIGH disables both A and B ports by placing then in a HIGH Z condition. The data inputs include active bushold circuitry eliminating the need for external pull-up resistors to hold unused or floating inputs at a valid logic state.
