Expert opinion by Night-Shift Neil · Maintenance Technician
The 74H53PC: Rated for 0°C to 70°C commercial temperature range.
Marked RoHS non-compliant. If your assembly line is RoHS-only (lead-free solder, no exemption), this part will fail incoming inspection. You'll need either a stock of legacy boards with leaded solder, or a RoHS-compliant alternative — though no direct drop-in is listed. Plan your BOM exemption paperwork now.
No, it is marked RoHS non-compliant. Leaded solder or an exemption is required for assembly.
