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. DIP-8 FEATURES * Low operating voltage: 2V ~ 5V. * On-chip RC oscillator. * Low stand by current. * CMOS process. *Pb-free plating product number: 1616L PIN CONFIGURATION OSC2 1 OSC1 2 8 SOFT 7 VDD UTC 1616 INI 3 6 BZ2 GND 4 5 BZ1 PIN DESCRIPTIONS Pin No 1 2 3 4 5 6 7 Symbol OSC2 OSC1 INI GND BZ1 BZ2 VDD I/O I O I O O - 8 SOFT I UTC Function Oscillator pin with external resistor. An internal pull-up resistor. Might disable BZ1, BZ2, when connected to GND. Power supply pin (-). Audio output pins. Power supply pin (+) . SOFT = VDD : 6 tones (1616)/single tone (1616A) with soft chirp. SOFT = OPEN : 6 tones (1616)/single tone (1616A) without soft chirp.
