    I was almost expecting to see an LM3909!

    Unfortunately, the LM3909 was discontinued as new LED parameters were generally not compatible.
    Apparently, the LM3909 could blink a red 5mm 2V 20mA for about 3 months until 1.5V battery ran flat.
    I still have 2 of these little workhorses in my stock. :D:D
