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.
