MIC1557 Overview
The MIC1555 IttyBitty CMOS RC timer/oscillator and MIC1557 IttyBitty CMOS RC oscillator are designed to provide rail-to-rail pulses for precise time delay or frequency generation. These devices are similar in function to the industry standard “555”, without a frequency control (FC) pin or an open-collector discharge (D) pin. The threshold pin (THR) has precedence over the trigger (TRG) input, ensuring that the...
