IS1U20

The IS1U20 is designed as one kind of OPIC light detectors for infrared communication (IrDA1.0 compatible). Typical applications include personal computers, portable information terminal equipment and printers and word processors.

The IS1U20 has five features. (1)IrDA1.0 compatible OPIC light detector (transmission rate 2.4 to 115.2kbps). (2)Compact design due to OPIC (number of parts 1). (3)Compatible with both 5V and 3V power supplies (operating supply voltage 2.7V to 5.5V). (4)Visible light cut-off type. (5)Recommended use in combination emitter. Those are all the main features.

Some absolute maximum ratings of IS1U20 have been concluded into several points as follow. (1)Its supply voltage would be from 0V to 6.0V. (2)Its operating temperature range would be from -10°C to 70°C. (3)Its storage temperature range would be from -20°C to 85°C. (4)Its soldering temperature would be 260°C. It should be noted that stresses above those listed in absolute maximum ratings may cause permanent damage to device.

Also some electrical characteristics of IS1U20 are concluded as follow. (1)Its dissipation current would be typ 1.0mA and max 1.4mA at Vcc=5V, no input light, output terminal OPEN and would be typ 0.7mA and max 1.0mA at Vcc=3V, no input light, output terminal OPEN. (2)Its high level output voltage would be min 4.5V at Vcc=5V and would be min 2.5V at Vcc=3V. (3)Its low level output voltage would be max 0.4V. (4)Its low level pulse width would be min 0.8us and max 16us at BR=2.4kbps and would be min 0.8us and max 8.0us at BR=115.2kbps. (5)Its rise time would be max 1.2us. (6)Its fall time would be max 0.2us. (7)Its max reception distance would be min 1m. And so on. At present we have not got so much information about this IC and we would try hard to get more information about IS1U20.
