Description
The MID400 is an optically isolated AC line-to-logic inter-
face 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 iso-
lation, solid state reliability, TTL compatibility, small size,
low power, and low frequency operations are required.

    ... The detector amplifier circuitry operates from supply and drives an open collector transistor output. The switching times are intentionally designed to be slow in order to enable the MID400, when used line monitor, to respond only to changes in input volt- age exceeding many milliseconds.
