16-bit bus transceiver for mixed-voltage backplanes
It handles bidirectional data flow between buses operating at different voltage levels, from 1.65 V up to 3.6 V, making it a natural fit for systems where a 3.3 V controller talks to a 1.8 V peripheral or where a legacy 2.5 V bus meets a 3.3 V FPGA bank. The 3-state outputs let multiple drivers share the same bus without contention.
Rated from 1.65 V to 3.6 V, this part covers the three most common logic supply rails — 1.8 V, 2.5 V, and 3.3 V — without needing a separate level translator. The 3.3 V compatibility question comes up often: yes, the SN74LVCH16245ADGGR is fully specified at 3.3 V and meets the VIH/VIL thresholds for 3.3 V CMOS and LVTTL logic families.
