The TLP1018 and TLP1019 are digital‑output photointerrupters that combine a GaAs infrared LED with a high‑sensitivity Si photo‑IC. They are used in home electric equipment such as VCRs and CD players, office equipment like printers and copiers, and automatic service equipment such as vending machines.
The document lists maximum ratings, opto‑electrical characteristics, recommended operating conditions, and precautions for soldering and packaging. It also includes graphs of relative output voltage versus shutter position and guidelines for proper shutter placement.
