E2P0046-37-X4 This version: Jan. 1998 Previous version: May. 1997 ¡ electronic components OCM1M4, 1M5 SERIES OPTICAL MOS RELAYS OCM1M4, 1M5 Series Low Output-capacitance Type Optical MOS Relay For DC Load Only GENERAL DESCRIPTION The OCM1M4 and OCM1M5 Series are optical MOS relays for DC load only that provide highspeed response and are capable of handling high-frequency signals. The input portion is an infrared light emitting diode. The output portion uses a combination of low-capacitance VDMOS (Vertical Diffusion MOS) FETs and photodiode arrays. The device is encased in an extremely small 6-pin plastic DIP or SMD-type (gull-wing) package. The optical MOS relay switch may be used in applications that currently use mechanical relay switches, but offers smaller size, noise-free switching, and electronic circuit compatibility because of its non-mechanical operation. Optical MOS relay switches also dissipate less power than equivalent bipolar devices at lower switching frequencies.
