SDT1670 DC Input 80V Quad Photo-Transistor Optocoupler Description Features 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. 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 The SDT1670 comes standard in an ultra-miniature 16 pin SSOP package.
