General Description

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