Hermetically Sealed

1,000V Isolation Voltage

6-pin LCC Package

Low Input Requirements

High Speed – typically 2 MHz


This device is a single channel, hermetically sealed optically coupled isolator.  It is composed of a Gallium Arsenide infrared emitting diode and a silicon phototransistor.

The CSM1801 is being used in environments encountered by space applications. This device is available in a LCC-6 package, with solder dip option available.  These packages have a shield effect to cut off ambient light as they are designed for high density mounting applications.

Absolute maximum ratings, recommended operating conditions, electrical specifications and performance characteristics are identical for all units. Any exceptions, due to packaging variations and limitations, are as noted in the datasheet.
