OPIC ■ FEATURES — — — — — Part No: 80-08-00002 Type: PS104C COMPACT BUILT-IN SCHMITT TRIGGER CIRCUIT HIGH SENSITIVITY (Ee: MAX 1mW/cm2 AT Ta=25℃) A WIDE RANGE OF OPERATING SUPPLY VOLTAGES (Vcc: 4.5∼17V) LSTTL AND TTL COMPATIBLE OUTPUT ■ APPLICATIONS — — — — FLOPPY DISK DRIVERS COPIERS, PRINTERS, FACSIMILES VCRS, CASSETTE DECKS AUTOMATIC VENDING MACHINES ■ GENERAL DESCRIPTIONS The circuit consists of a photodiode, amplified circuit, a decision circuit (schmidt trigger circuit) and an output buffer circuit. When the light comes, the circuit will sense the signal and give a corresponding output signal. PS103C/104C will generate a digital signal off/on corresponding to the incoming light which is on/off. The output buffer will give a TTL compatible output signal from the digital signal. With build-in regulator, this circuit has a wide operation range. ■ CHIP SIZE PIN 1: GROUND, PIN 2: OUTPUT, PIN 3: Vcc (UNIT: mm) X CHIP CENTER Y 1.25 + 0.537 PIN 1: (-650,-465)um PIN 2: (399,-388)um PIN 3: (646,-465)um CHIP CENTER(0,0)um PD CENTER(-10,-162)um PAD SIZE: 110x110um + P.D CENTER 0.539 2 3 1 1.62 OPTO TECH Since 1983 Microelectronics Business Division 2003.01 1/1 OPTO TECH CORPORATION Tel: 886-3-5638951 Fax: 886-3-5783696 http://www.opto.com.tw
