Overview
XR·L555 Micropower Timing Circuit GENERAL DESCRIPTION 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 555-timer and can operate down to 2.
7 volts without sacrificing such key 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 tim...
