74VCX16245 LowVoltage 1.8/2.5/3.3V 16Bit Transceiver With 3.6 VTolerant Inputs and Outputs (3State, NonInverting) http://onsemi.com The 74VCX16245 is an advanced performance, noninverting 16bit transceiver. It is designed for very highspeed, very lowpower operation 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 tolerate voltages it may encounter on either inputs or outputs when interfacing to 3.3 V busses. It is guaranteed to be overvoltage tolerant to 3.6 V. The VCX16245 is designed with byte control. It can be operated as two separate octals, or with the controls tied together, as a 16bit wide function. The Transmit/Receive (T/Rn) inputs determine the direction of data flow through the bidirectional transceiver. Transmit (activeHIGH) enables data from A ports to B ports; Receive (activeLOW) 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.
