LS121 Datasheet PDF

Micross LS121

The LS121 is a monolithic pair of NPN transistors mounted in a single P-DIP package. The monolithic dual chip design reduces parasitics and gives better performance while ensuring extremely tight matching. The LS121 is a direct replacement for discontinued Intersil IT121.
