MIC1555, 1557
IttyBitty® RC Timer, Oscillator
General Description
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.
The devices are similar in function to the industry standard “555”, without a frequency control (FC) pin or an opencollector discharge (D) pin. The threshold pin (THR) has precedence over the trigger (TRG) input, ensuring that the BiCMOS outpu
