Microchip (MIC1557YM5-TR) Timer, Oscillator IC, IttyBitty CMOS RC, Astable

Timer, Oscillator IC, IttyBitty CMOS RC, Astable, 5 MHz, 2.7 V to 18 V, SOT-23-5Product OverviewThe MIC1557YM5 TR is an Itty-bitty® RC Timer or Oscillator designed to providerail-to-rail pulses for precise time delay or frequency generation. The deviceis similar in function to the industry standard 555 without a frequency control(FC) pin or an open collector discharge (D) pin. The threshold pin (TH) hasprecedence over the trigger (TR) input, ensuring that the BiCMOS output is offwhen TR is high. The oscillator may be used as an a stable (oscillator) ormonostable (one-shot) with separate threshold and trigger inputs. In theone-shot mode, the output pulse width is precisely controlled by an externalresistor and a capacitor. Time delays may be accurately controlled frommicroseconds to hours. In the oscillator mode, the output is used to provideprecise feedback with a minimum of one resistor and one capacitor producing a50% duty cycle square wave.Timing from microseconds to hoursThreshold input precedence over trigger inputNo output cross-conduction current spikesApplicationsClock & Timing, LED Lighting, Power ManagementProduct InformationFrequency: 5MHzSupply Voltage Min: 2.7VSupply Voltage Max: 18VDigital IC Case: SOT-23No. of Pins: 5PinsOperating Temperature Min: -40°COperating Temperature Max: 85°C
