Low input current optocouplers in SOP-4 Mini-flat package

摘要

Vishay Intertechnology's VOM617A and VOM618A series of optoelectronics with low input current optocouplers and phototran-sistor outputs feature low input currents of 1 mA (VOM618A) and 5 mA (VOM617A) in the compact SOP-4 mini-flat package. This saves 30% PCB space over the DIP-4 package.Both models in the series each offer nine different current transfer ratio (CTR) ranges from 40 to 600%, providing designers with increased flexibility.
