UNISONIC TECHNOLOGIES CO., LTD 1618 CMOS IC 6 KEYS SIREN/ALARM SOUND GENERATOR DESCRIPTION The UTC 1618 is a CMOS design for 6 different alarm sounds application. According to the priority of the select keys, the sound of UTC 1618 will be generated in cycling sequence. FEATURES * Auto power off function, reduce power consumption. * Low operating voltage: 2V ~ 5V. * On-chip RC oscillator. * 6 different sounds. * 6 prioritized keys for selecting 6 different sounds. * Low stand by current. * CMOS process. Lead-free: 1618L Halogen-free: 1618G ORDERING INFORMATION Normal 1618-D16-T Ordering Number Lead Free 1618L-D16-T www.unisonic.com.tw Copyright © 2008 Unisonic Technologies Co., Ltd Halogen Free 1618G-D16-T Package Packing DIP-16 Tube 1 of 5 QW-R502-007.E 1618 CMOS IC PIN CONFIGURATION VDD 1 16 NC S3 2 15 NC S5 3 14 OSC2 S4 4 13 OSC1 S6 5 12 BZ2 S2 6 11 BZ1 S1 7 10 NC GND 8 9 INI UTC 1618 PIN DESCRIPTIONS PIN # 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 PIN NAME VDD S3 S5 S4 S6 S2 S1 GND INI NC BZ1 BZ2 OSC1 OSC2 NC NC I/O I I I I I I I O O O I O DESCRIPTION Power supply pin (+). Sound selection keys. These keys connect with internal pull-down resistors. The sound output will be enabled when a key is connected to VDD. On other hands, the sound output will be disabled if a key is N.C. or connected to GND. When two or more keys are selected in the same time, the sound will be generated in cycling sequence. According to the priority of the keys, the proirity of S1~S6 list below : S1>S2>S6>S4>S5>S3. Power supply pin (-). An internal pull-up resistor. Might disable BZ1, BZ2, when connected to GND. No connecting. Audio output pins. Oscillator pin with external resistor. No connecting. No connecting.
