Dual Supply Translating Transceivers Provide Two-Way Interface

Two-way asynchronous communication between buses operating at different voltage levels is possible with the 74VCX163245 and 74VCX164245 dual supply translating transceivers. The dual supply, 16-bit translating devices provide a bi-directional interface between buses operating at mixed voltage levels between 1.65V and 3.6V, providing true signal translation. Both devices support live insertion and withdrawal. Applications include a variety of new systems that must interface between new, lower voltage technologies and legacy designs operating at a higher voltage level. Applications such as telecommunications, portable computers or PDA equipment are targets due to their extensive use of mixed voltage levels to maximize power savings by using 1.65V wherever possible and 3.6V only where necessary. Available in 48-lead TSSOP packaging, the devices are priced at $2.19 each/1,000.
