The LM556 is a dual timer IC, similar to 555 Timer IC but here it has two such timer devices into a single package. It is considered to be the modern replacement for 555 since it uses the latest CMOS technology.

NE555 Timer IC has an operating voltage from +5V to +18V and the output pin can source/sink up to 150mA current. The minimum threshold voltage for the trigger pin is 2.4V when operated with 5V.
