ML4632CS Datasheet PDF - Micro Linear Corporation

GENERAL DESCRIPTION
The ML4632 is a fiber optic LED driver suited for network applications up to 20Mbps. The part is capable of driving up to 100mA of current through a Fiber Optic LED from an ECL or TTL level input signal. Its efficient output stage provides a high current that can be programmed for accurate absolute output level as well as automatic temperature compensation. The combination of automatic temperature compensation and a highly accurate current driven design insures precise launch power.
