Device identity and function
The Texas Instruments TLC34075-66AFN is a Palette DAC designed to drive 1024 x 768 pixel resolution displays — the XGA-class video output common in late-90s to mid-2000s workstation monitors and embedded video cards. The part is listed in Bulk packaging, indicating tray or tube delivery rather than tape-and-reel; the package type is not further specified in the record, so the mechanical footprint must be confirmed against the original TI datasheet before committing a PCB layout.
Lifecycle and compliance reality
RoHS non-compliance means the part contains lead or other restricted substances above the RoHS exemption thresholds. This is a sourcing constraint: the part cannot be used in new EU-market products without a RoHS exemption claim, but it remains viable for repair, military, or exempt industrial applications where lead-free requirements do not apply.
