1617

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.

FEATURES 

* Low operating voltage: 2V ~ 5V. 

* On-chip RC oscillator. 

* Low stand by current. 

* CMOS process.
