The XR1488N is designed as one kind of monolithic timer / controller capable of producing ultra-long time delays from milliseconds to days. Two timing circuits can be cascaded to generate time delays or timing intervals up to one year. The circuit is comprised of an internal time-base oscillator, and 8 bit binary counter and a control flip-flop.
Features of the XR1488N are:(1)timing from micro-seconds to days;(2)wide supply range: 4.5 V to 15 V;(3)TTL and HCMOS compatible outputs;(4)high accuracy: 0.5%;(5)excellent supply rejection: 0.2 %/V;(6)monostable and astable operation. And this device can be used in long delay generation, sequential timing, precision timing and ultra-low frequency oscillator applications.
The absolute maximum ratings of the XR1488N can be summarized as:(1)power supply: 18 volts;(2)power dissipation (package limitation) ceramic package: 385 mW;(3)power dissipation (package limitation) plastic package: 300 mW;(4)power dissipation (package limitation) derate above +25: 2.5 mW/;(5)storage temperature range: -65 to +150 .
