Copiers, Printers and Fax Machines Air Conditioners Game Machines
The TLP1255 (C8,Q) is a compact photointerrupter with a built-in connector, which uses a GaAs infrared LED and a Si photo-IC. Designed for 3.3/5 V systems, the device can operate at temperatures of up to 95C. When the light is shielded, outputs are at high level. Small package Compared to Toshiba's TLP1253 (C6,Q) , the volume and the mounting area of the TLP1255 (C8,Q) are reduced to 70% and 75% respectively. Three board thicknesses supported: 1.0 mm, 1.2 mm and 1.6 mm Gap: 5 mm Resolution: Slit width = 0.7 mm Designed for 3.3 /5 V system High-temperature operation: Topr = 95C (max) Low current consumption: ICC = 14 mA (max) Digital output (open collector) Mini CT connector (1.5 mm pitch MT RECEPTACLE ASSEMBLY / HOUSING CRIMP TYPE) made by Tyco Electronics AMP, Ltd. Package and connector material: Polycarbonate (UL94V-2) Lead(Pb)-Free Finish TOSHIBA Weight: 0.8 g (typ.) 11-15H1

Note: Using continuously under heavy loads (e.g. the application of high temperature/current/voltage and the significant change in temperature, etc.) may cause this product to decrease in the reliability significantly even if the operating conditions (i.e. operating temperature/current/voltage, etc.) are within the absolute maximum ratings and the operating ranges. Please design the appropriate reliability upon reviewing the Toshiba Semiconductor Reliability Handbook ("Handling Precautions"/"Derating Concept and Methods") and individual reliability data (i.e. reliability test report and estimated failure rate, etc).

Precautions
At power-on the internal circuit takes about 100 s to stabilize. During this period any output signal would be unstable and liable to change. Design the circuit so that no signal is output during this period. The device when installed should be protected from interference by ambient light. The integrated phototransistor is insensitive to light of 700 nm or less (e.g., fluorescent light), but is sensitive to light above 700 nm (e.g., incandescent light). Detecting ambient light may cause the device to trigger a malfunction. Test and evaluate thoroughly any end-equipment in which the device is used to ensure that no such interference will occur. Take due care regarding the environment in which the device is to be installed. Oil or chemicals may cause the package to melt or crack. When attaching the device to the metal board, always hold the body of the device. Do not hold it by the connector. Ensure that the board is flat, and not warped or twisted. Attach the device to a metal board at room temperature. Toshiba recommends attaching the device to the smoother side of the board. Toshiba recommends testing the attachment strength beforehand by actually attaching a device to the board. Do not apply solder to the pins of the device connector. Make sure that the connector is linked to the Mini CT connector or equivalent connector. When inserting or removing the Mini CT connector or equivalent connector, always grasp the connector and its cable firmly and either plug the connector into or pull it out of the device connector straight and not at an angle. Inserting or removing the Mini CT connector or equivalent connector at an angle may cause damage to both the connector of the device and the Mini CT connector or equivalent connector, resulting in an unreliable connection. The leadframe of the package and the resistance are exposed, as shown below. Design the housing and chassis of end-equipment with particular care to ensure that no conductive material or object (such as a metal pin) drops on the leads of the leadframe or on both ends of the resistance terminal to cause a short circuit between them.
