The OLS100 is designed especially for applications that require optical isolation with a high CTR and low saturation VCE. Each OLS100 device consists of an LED and N-P-N silicon phototransistor, mounted and coupled in a custom hermetic surface-mount Leadless Chip Carrier (LCC) package. The low input current makes the OLS100 well-suited for direct Complementary Metal Oxide Semiconductor (CMOS) to Low Power Schottky Transistor (LSTTL) to Transistor Logic (TTL) interfaces. The OLS100 device can be mounted using reflow soldering or conductive epoxies.
