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.
