General Description
The EL6242C is a high-performance three channel laser driver that provides controlled current to a grounded laser diode. Write channels 2 and 3 should be used as the write channels, with switching speeds of approximately one nanosecond rise/fall time.
FEATUREs
• Shrink-Small Outline Package
