MID400
Description
The MID400 is an optically isolated AC line- to- logic interface device. It is packaged in an 8- lead plastic DIP. The AC line voltage is monitored by two back- to- back Ga As 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.
The MID400 has been designed solely for the use as an AC line monitor. It is remended for use in any AC- to- DC control application where excellent optical isolation, solid state reliability, TTL patibility, small size, low power, and low frequency operations are required.
