    ELQ3H4是亿光的4合1光耦，体积小，贴片封装，可以替代安华高的ACPL-244,东芝的TLP280-4,TLP290-4,NEC的PS2805-4.四合一的光耦比较单独4颗光耦，占用空间更小，贴片更方便，很多数控主板，总线控制上有广泛应用。

ELQ3H4特点：

Description
The ELQ3H4 is optically coupled isolator containing GaAs light emitting diodes and an NPN
silicon phototransistors in a plastic SOP for high density applications.
This package has shield effect to cut off ambient light.
Applications
