74VCXH16245
Low−Voltage 1.8/2.5/3.3V16−Bit Transceiver
With 3.6 V−Tolerant Inputs and Outputs(3−State, Non−Inverting)
The 74VCXH16245 is an advanced performance, non−inverting16−bit transceiver. It is designed for very high−speed, very low−poweroperation in 1.8 V, 2.5 V or 3.3 V systems.
When operating at 2.5 V (or 1.8 V) the part is designed to toleratevoltages it may encounter on either inputs or outputs when interfacingto 3.3 V busses. It is guaranteed to be over−voltage tolerant to 3.6 V.The VCXH16245 is designed with byte control. It can be operatedas two separate octals, or with the controls tied together, as a 16−bitwide function. The Transmit/Receive (T/Rn) inputs determine thedirection 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 Enableinputs (OEn), when HIGH, disable both A and B ports by placing themin a HIGH Z condition. The data inputs include active busholdcircuitry, eliminating the need for external pull−up resistors to holdunused or floating inputs at a valid logic state.

*NOTE: To ensure the outputs activate in the 3−state condition, the output enable pins should be connected to VCC through a pull−up resistor. The value of the resistor is determined by the current sinking capability of the output connected to the OE pin.© Semiconductor Components Industries, LLC, 20041May, 2004 − Rev. 3
