MIC1557YM5-TR MICROCHIP Programmable Timers and Oscillators

MIC1557YM5-TR Selection & Applications Choose this IttyBitty® CMOS timer when you need a low-power, high-speed 555-compatible oscillator in minimal board space. Its 2.7V–18V supply range and 130µA typical consumption suit battery-powered devices, while 5MHz capability handles fast timing beyond standard 555 limits. Configure as monostable one-shot, astable free-running oscillator, or precision pulse generator. Ideal for LED flashers, power-on reset delays, PWM generators, missing-pulse detectors, watchdog timers, and tone generation in portable instruments, industrial sensors, and consumer electronics. The SOT-23-5 package delivers full 555 functionality at a fraction of the footprint. In stock at HL Electronics – request a quote for fast delivery.
