The LM2240 Programmable Timer Counter is a monolithic controller capable of both monostable and astable operation Monostable operation allows accurate microsecond to five day time delays Long delays up to three years can easily be generated by cascading two timers The timer consists of a time-base oscillator programmable 8-bit counter and control flip-flop An external resistor-capacitor (RC) network sets the oscillator frequency and allows delay times from 1 RC to 255 RC to be selected In the as
