OLH5530 / OLH5531
Hermetic High-speed Transistor Dual-Channel Optocoupler

The OLH5530/5531 are dual-channel hermetic 8-pin DIP optocouplers for wide bandwidth analog applications, as well as for interfacing Transistor-to-Transistor Logic (TTL) to Low-Power Schottky Transistor-Transistor Logic (LSTTL) or Complementary Metal Oxide Semiconductors (CMOS). The OLH5531 product is a 100 percent high-reliability screened version of the OLH5530.

Each unit consists of an Aluminum Gallium Arsenide (AlGaAs) LED optically coupled to an integrated photodiode transistor detector. The separate photodiode and transistor configuration improves speed performance significantly over phototransistors.

The OLH5530/5531 products are functionally compatible to 6N135, 6N136, 4N55, and HCPL5530/5531 optocouplers, but with better common mode transient immunity. Special Current Transfer Ratio (CTR) selection is available upon request.

The performance of the OLH5530/5531 under a radiation environment is significantly improved over standard phototransistors.
