Overview
JLA2240 PROGRAMMABLE TIMER/COUNTER FAIRCHILD LINEAR INTEGRATED CIRCUITS GENERAL DESCRIPTION - The /lA2240 Programmable Timer/Counter is a monolithic controller capable of producing 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-t>ase 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 astable mode of operation, 255 frequencies or pulse patterns can be generated from a single RC network.
These frequencies or pulse patterns can also easil...
