micropower dual timer.
as timing accuracy and stability. At 5 volt operation, typical power dissipation of the dual-timer circuit is less than 2 mW; and it can operate in excess of 500 hours wi.
requiring very low power dissipation. Each section of the XR-L556 dual timer is equivalent to Exar's XR-L555 micropower .
The XR-L556 dual timer contains two independent micropower timer sections on a monolithic chip. It is a direct replacement for the conventional 556-type dual timers, for applications requiring very low power dissipation. Each section of the XR-L556 .
