XR-L555 Micropower Timing Circuit

FUNCTIONAL BLOCK DIAGRAM The XR-L555 is a stable micropower controller capable of producing accurate timing pulses. It is a direct replacement for the popular 555-timer for applications requiring very low power dissipation. The XR-L555 has approximately 1/15th the power dissipation of the standard.

XR-L555 Features

* as timing accuracy and frequency stability. At 5-volt operation, typical power dissipation of the XR-L555 is 900 microwatts. The circuit contains independent control terminals for triggering or resetting if desired. In the monostable mode of operation, the time delay is controlled by one external r
