QTC - MID400 - IC. AC Line Monitor Logic-Out Device. 8 Pin Dip

QTC - MID400 - IC. Optocoupler AC Line Monitor Logic-Out Device. The MID400 is an Optically Isolated AC Line-to-Logic Optocoupler. The AC line voltage is monitored by two back-to-back GaAs LED diodes in series with an external resistor. A high gain detector circuit senses the LED current and drives the output gate to a logic low condition. It has been designed solely for the use as an AC line monitor. It is recommended for use in any AC-to-DC control application where excellent optical isolation, solid state reliability, TTL compatibility, small size, low power and low frequency operations are required. • Direct operation from any line voltage with the use of an external resistor • Externally adjustable time delay • Externally adjustable AC voltage sensing level • High voltage isolation between input and output • Logic level compatibility Input Type: AC, DC Current - Output / Channel: 20mA Propagation Delay tpLH / tpHL (Max): 1ms, 1ms (Typ) Voltage - Forward (Vf) (Typ): 1.5 V Current - DC Forward (If) (Max): 30 mA Voltage – Supply: 7V Operating Temperature: -40°C ~ 85°C Mounting Type: Through Hole Package / Case: 8-DIP (0.300", 7.62mm) Applications: Monitoring of the AC/DC “Line−down” Condition, “Closed−loop” Interface between Electromechanical Elements such as Solenoids, Relay Contacts, Small Motors, and Microprocessors, Time Delay Isolation Switch.
