ILQ615-1

The ILQ615-1 is a 4-channel 16-pin Phototransistor Output Optocoupler uses GaAs IRLED emitters and high gain NPN phototransistors. This device is constructed using over/under lead-frame optical coupling and double moulded insulation technology resulting a withstand test voltage of 7500VAC peak and a working voltage of 1700VRMS. The binned minimum/maximum and linear CTR characteristics make these devices well suited for DC or AC voltage detection. Eliminating the phototransistor base connection provides added electrical noise immunity from the transients found in many industrial control environments. Because of guaranteed maximum non-saturated and saturated switching characteristics, the ILQ615 can be used in medium speed data I/O and control systems. The binned minimum/maximum CTR specification allows easy worst case interface calculations for both level detection and switching applications. Interfacing with a CMOS logic is enhanced by the guaranteed CTR at IF=1mA.
