Dual-supply bus translator for mixed-voltage backplanes
The Texas Instruments SN74LVCH8T245PWR is a dual-supply translation transceiver from the 74LVCH series, designed to bridge logic levels between two voltage domains on a single board. It contains two 8-bit bidirectional transceiver elements with 3-state outputs, each capable of sinking or sourcing 32 mA. The part operates from 1.65 V up to 5.5 V on either supply rail. Housed in a 24-TSSOP package (4.40 mm wide).
32 mA drive — what it means for bus loading
The 32 mA output current rating (both high and low) determines how many loads this transceiver can drive. At 32 mA per channel, the part is suited to point-to-point links or short bus segments.
Industrial temperature range and environment
It is not rated for the full automotive under-hood range.
For a BOM line, this part is safe to qualify into new designs without worrying about a forced redesign cycle. ROHS3 compliant.
