UTC 1617
CMOS IC
6 TONES SIREN/ALARM
SOUND GENERATOR
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.
