The NE555M/TR Timers / Clock Oscillators with 500kHz SOP-8 ROHS manufactured by HGSEMI are integrated circuits that are used as a loop signal generator for clock pulses. They are typically used in applications such as pulse generation, delay, and oscillator functions. This particular product is made of high quality components and has an operating temperature range from -40 to +85 degrees Celsius, a maximum operating supply voltage of 15V, an output current of 10mA, and an output pulse width of 3.3µs. The NE555M/TR also features a power down feature, allowing for the device to be used in battery-operated applications without draining the battery power unnecessarily.
