UTC1616

UTC 1616 CMOS IC 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.
