6 TONES SIREN/ALARM

SOUND GENERATOR

WITH SOFT CHIRP

DESCRIPTION

The UTC 1616 is a CMOS design for 6 different alarm sounds

application. The sound of UTC 1616 will be generated in cycling

sequence. The soft chirp is only generated within 200ms of the

1st sound.

By the way, UTC 1616 is also partitioned for single tone

siren/alarm sound generator with soft chirp, 1616A. The types of

UTC 1616 Series are listed as following.

1616: 6 tones with 200ms soft chirp in the 1st sound.

1616A: Single tone with 200ms soft chirp on chip.

FEATURES

* Low operating voltage: 2V ~ 5V.

* On-chip RC oscillator.

* Low stand by current.

* CMOS process.

DIP-8

*Pb-free plating product number: 1616L
