SDT1670

SDT1670 DC Input 80V Quad Photo-Transistor Optocoupler Description The SDT1670 consists of four phototransistors, each optically coupled to a light emitting diode. Optical coupling between the input IR LED and output phototransistor allows for high isolation levels while maintaining low-level DC signal control capability. The SDT1670 provides an optically isolated method of controlling many interface applications such as telecommunications, industrial control and instrumentation circuitry. The SDT1670 comes standard in an ultra-miniature 16 pin SSOP package. Applications  Office Automation Equipment  System Appliances, Measuring Instruments  Computer Terminals, PLCs  Telecom / Datacom  Home Appliances  Digital Logic Inputs  Fax / Modems  Power Supplies Schematic Diagram Features  Ultra miniature 16 pin SSOP package  Low input power consumption  High stability  CTR Range 50 – 600%  High Isolation Voltage (3750VRMS)  Long Life / High Reliability  RoHS / Pb-Free / REACH Compliant Agency Approvals UL/C-UL: VDE: File # E201932 File # 40035191 (EN 60747-5-2) Absolute Maximum Ratings The values indicated are absolute stress ratings.
