16-bit bus transceiver for mixed-voltage backplanes
It integrates two 8-bit elements with independent direction and output-enable controls, each element capable of sinking or sourcing 24mA per pin.
Wide supply and temperature coverage
Rated from 1.65V up to 3.6V, this part works on a 1.8V core rail and a 3.3V I/O rail without a separate level shifter — one BOM line covers both. If the board sits in an engine bay, an outdoor base station, or a factory floor with no climate control, this temperature grade is what keeps the bus from bit-flipping on a hot afternoon.
Each of the 16 I/O pins can source or sink 24mA. That is enough to drive a heavily loaded backplane trace, a bank of LED indicators, or a parallel memory bus. But the 24mA figure is per-pin; the total package dissipation at full simultaneous drive needs a quick thermal check — 16 pins × 24mA × V_OH drop at 3.6V adds up fast. For most bus applications the transceiver is not driving all lines at full DC current, but if this part is used as a general-purpose GPIO expander with high-current loads, budget a thermal pad via stitch under the 48-SSOP.
