74VCXH16245

Low−Voltage 1.8/2.5/3.3V

16−Bit Transceiver

With 3.6 V−Tolerant Inputs and Outputs

(3−State, Non−Inverting)

16−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.

voltages it may encounter on either inputs or outputs when interfacing

to 3.3 V busses. It is guaranteed to be over−voltage tolerant to 3.6 V.

as two separate octals, or with the controls tied together, as a 16−bit

wide function. 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

inputs (OEn), when HIGH, disable 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.

Features

*NOTE: To ensure the outputs activate in the 3−state condition,

the output enable pins should be connected to V

pull−up resistor. The value of the resistor is determined by the

current sinking capability of the output connected to the OE pin.
