Broadcom 2 Channel Darlington Optocoupler, DIP, 8 Pins, 3.75 kV
Broadcom 2-channel Darlington optocoupler in DIP-8 package. Features 3.75kV isolation and 300% min CTR for signal processing and networking.
This 2-channel 8-pin low input current high gain optocoupler from Broadcom contains a separated pair of GaAsP light emitting diodes optically coupled to a pair of integrated high gain photodetectors. It provides an extremely high current transfer ratio and excellent input-output common mode transient immunity, making it a reliable choice for demanding electronic applications.
A separate pin for the photodiodes and first gain stages (VCC) permits a lower output saturation voltage and higher speed operation than is possible with a conventional photodarlington type optocoupler. In addition, the VCC may be as low as 1.6V without adversely affecting the parametric performance. The outstanding high temperature performance of this split Darlington type output amplifier results from the inclusion of an integrated emitter-base bypass resistor, which shunts photodiode and first stage leakage currents to ground.
It is specified at an input current of 1.6mA and has a 7V VCC and VO rating. The 300% minimum current transfer ratio (CTR) allows TTL to TTL interfacing at this input current. With a typical high current transfer ratio of 1800%, a low input current of 0.5mA, a low output saturation voltage of 0.1V, and a high output current of 60mA, this component delivers outstanding electrical performance for a variety of circuits.
