The 74VCX163245 is a dual supply, 16-bit translating transceiver that is designed for 2 way asynchronous communication between busses at different supply voltages by
providing true signal translation. The supply rails consist V_CCA, of the 74VCX163245 which is a higher potential rail operating at 2.3V 3.6V and V_CCB, which is the lower potential rail operating 1.65V to 2.7V. (VCCB must be less than or equal to V_CCA for proper device operation). This dual supply design allows for translation from 1.8V to 2.5V busses to busses a higher potential, up to 3.3V.

The Transmit/Receive (T/R) input of the 74VCX163245 determines the direction of data flow. Transmit (active-HIGH) enables data from 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 High-Z condition. The A Port interfaces with the higher voltage bus (2.7V to 3.3V); The B Port interfaces with the lower voltage bus (1.8V to 2.5V). Also the VCX163245 designed so that the control pins (T/Rn, OEn) are supplied by V_CCB.

The 74VCX163245 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.
