Brand: ERA

ERA 555 is a timing circuit integrated circuit (IC) that was first introduced by Motorola (now part of On Semiconductor) in 1980. It is widely used in many electronic devices such as alarm clocks, electronic timers, and stopwatches.The ERA 555 is a versatile and user-friendly IC that provides reliable, stable, and accurate timing functions. It operates on a supply voltage between 4.5 V and 6.0 V and has a standby current of less than 50 μA.The IC has two output signals, the THR (Trigger) and the OUT (Output) pins, which are complementary and can be used to generate pulses or signals with adjustable frequency, width, and duty cycle. The time-base can be configured by adjusting a few external resistors and capacitors, which enable applications with different time durations ranging from milliseconds to seconds.The ERA 555 is easy to use, with a simple operational principle, and is designed for simplicity and stability. It ensures precise and predictable results, making it a popular choice in everyday electronic applications.Some unique features of the ERA 555 IC include an internal voltage reference, an adjustable internal frequency, a reset input to clear the internal timer register, and a hold input to temporarily halt the timer operation. Additionally, it has a clear output that can be used to reset the IC when desired.In summary, the ERA 555 IC offers a timely solution for a wide range of applications, including time-delay circuits, astable and monostable multivibrators, and frequency dividers. It is an essential component in electronic design, and its long-standing reputation for accuracy and reliability makes it a go-to choice for many electronic engineers and hobbyists.
