OLH5500 / OLH5501
Hermetic High-speed Optocouplers

The OLH5500/5501 are 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 OLH5501 product is a 100 percent high-reliability screened version of the OLH5500.

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 base of the transistor is available for gain and bandwidth adjustments.

The OLH5500/5501 products are functionally compatible to 6N135, 6N136, 4N55, and HCPL5500/5501 optocouplers, but with better common mode transient immunity. Special Current Transfer Ratio (CTR) selection or no-transistor base connection versions for improved noise immunity is available upon request.

The performance of the OLH5500/5501 under a radiation environment is significantly improved over standard phototransistors.
