Each of the two elements handles one bit, sourcing or sinking 32 mA per output. The 3-state outputs allow bus sharing: when the output-enable pin is asserted, the output follows the input; when deasserted, the output goes high-impedance, letting multiple devices drive the same line.
Temperature range and package — industrial and compact
The 8-VFSOP (2.30 mm width) and equivalent 8-VSSOP package is a compact surface-mount footprint — roughly half the board area of a standard SOIC-8. The narrow body demands careful land pattern design; the datasheet's recommended footprint should be followed to avoid tombstoning during reflow.
