The NE555P with Timers & Support Products Precision manufactured by Texas Instruments is a highly reliable and cost-effective precision timing device suitable for use in a variety of electronic applications. It is based on the classic 555 timer IC, with improvements made to increase noise immunity and performance over a wider operating temperature range. The precision version also improves the temperature stability of the fixed resistance-capacitance (RC) circuit timing elements, resulting in more accurate timing performance and stability over a wide operating temperature range. It features a wide working voltage range from 4.5V-18V, an adjustable current sourcing up to 200mA, and has the ability to generate symmetrical and asymmetrical pulses that can be set from microseconds to hours. With its precision timing performance and improved temperature stability, the NE555P provides reliable accuracy for your application's timing needs.
