General Description

The VCX163245 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 of VCCA, which is a higher potential rail operating at 2.3V to 3.6V and VCCB, which is the lower potential rail operating at 1.65V to 2.7V. (VCCB must be less than or equal to VCCA 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.
