74VCXH245

Low−Voltage 1.8/2.5/3.3V

8−Bit Transceiver

(3-State, Non-Inverting with Bushold)

The 74VCXH245 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.

http://onsemi.com

The 74VCXH245 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 them 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.
