74VCX164245 − Low Voltage 16-Bit Dual Supply Translating Transceiver with 3-STATE Outputs

The VCX164245 is a dual supply, 16-bit translating transceiver that is designed for two way asynchronous communication between busses at different supply voltages by providing true signal translation. The supply rails consist of V_CCB, which is the higher potential rail operating at 2.3V to 3.6V and V_CCA, which is the lower potential rail operating at 1.65V to 2.7V. (V_CCA must be less than or equal to V_CCB for proper device operation.) This dual supply design allows for translation from 1.8V to 2.5V busses to busses at a higher potential, up to 3.3V.     The Transmit/Receive (T/R#) input determines the direction of data flow. Transmit (active-HIGH) enables data from A Ports to B Ports. Receive (active-LOW) enables data from B Ports to A Ports. The Output Enable (OE#) input, when HIGH, disables both A and B Ports by placing them in a High-Z condition. The A Port interfaces with the lower voltage bus (1.8V - 2.5V). The B Port interfaces with the higher voltage bus (2.7V - 3.3V). Also the VCX164245 is designed so that the control pins (T/R#_n, OE#_n) are supplied by V_CCB.     The 74VCX164245 is suitable for mixed voltage applications such as notebook computers using a 1.8V CPU and 3.3V peripheral components. It is fabricated with an Advanced CMOS technology to achieve high speed operation while maintaining low CMOS power dissipation.
