OPL550-OC [TT Electronics]

The Photologic Sensor series integrates a photodiode, amplifier, voltage regulator, Schmitt trigger, and NPN output transistor on a single silicon chip. These devices are housed in a molded plastic side-looking package with an integral lens (recessed for OPL535/OPL536), providing enhanced optical coupling and mechanical protection. The Schmitt trigger hysteresis offers high noise immunity. They feature TTL/LSTTL compatible logic level outputs with various options: internal 10K pull-up resistors (OPL530/531/535/536), totem pole outputs (OPL550/551/560/561/562/563), and open-collector variants. Operating supply voltage ranges from 4.5V to 16V for most series (4.5V to 5.5V for OPL550/551), with low power consumption and RoHS compliance. Data rates up to 250 kBaud (200 kBaud for OPL560 series).
