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.
PIN CONFIGURATION
DIP-8
*Pb-free plating product number: 1616L
