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 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.

The MID400 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.
