ption The LM122 series are precision timers that offer great versatility with high accuracy They operate with unregulated supplies from 4 5V to 40V while maintaining constant timing periods from microseconds to hours Internal logic and regulator circuits complement the basic timing function enabling the LM122 series to operate in many different applications with a minimum of external components The output of the timer is a floating transistor with built in current limiting It can drive either ground referred or supply referred loads up to 40V and 50 mA The floating nature of this output makes it ideal for interfacing lamp
