DESCRIPTION
The UTC 1617 is a CMOS design for 6 different alarm sounds application. The sound of UTC 1617 will be generated in cycling sequence.
By the way, UTC 1617 is also partitioned to 6 types for single tone siren/alarm sound generator. The types of UTC 1617 Series are listed as following.
   1617: 6 tones on chip.
   1617A: Single tone which be outputted from 1617’s 1st sound.
   1617B: Single tone which be outputted from 1617’s 2nd sound.
   1617C: Single tone which be outputted from 1617’s 3rd sound.
   1617D: Single tone which be outputted from 1617’s 4th sound.
   1617E: Single tone which be outputted from 1617’s 5th sound.
   1617F: Single tone which be outputted from 1617’s 6th sound.
