TPS841(F),TPS843(F) TOSHIBA Photo-IC Silicon Epitaxial Planar TPS841(F),TPS843(F) Photoelectric Switches Copiers, Printers, and Facsimiles Vending Machines Handy Terminals Unit: mm The TPS841(F) and TPS843(F) represent a Si photo IC of digital output type that integrates a photodiode, amplifier circuit, and Schmitt trigger circuit into a single chip. These devices are low voltage drive types, and they allow construction of low voltage systems which thus consume less power. These devices respond faster than the phototransistor type. They output a high when light is input. * * * * * * Compact side-view epoxy resin package Operates over a wide supply voltage range : VCC = 2.7 to 15 V High speed response : tpLH = 9 s, tpHL = 15 s (max) High sensitivity: 0.3 mW/cm2 (max) Can be directly connected to TTL and CMOS.

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).

TPS841(F) (TPS841(F)) TPS843(F) (TPS843(F)) Precautions * When you consider a combined use with an LED, be sure to use an infrared LED. Visible rays in wavelength of less than 700 nm cannot be detected. * Make sure the shielding plate that is used to detect positions is manufactured from materials with superior light-shielding characteristics. Insufficient shield can cause malfunction. * Photo ICs contain a high-sensitivity amplifier. Toshiba recommends connecting a capacitor of about 0.01 F that has good high-frequency characteristics between VCC and GND near the device to prevent unwanted oscillation. * Please install so that disturbance light is not irradiated by these products. When disturbance light (incandescence light etc.) 700 nm or more is detected, it may incorrect-operate. Please perform sufficient evaluation and verification by set. * During 100 s after turning on VCC, output voltage changes for stabilizing the inner circuit. 3 2007-10-01 TPS841(F),TPS843(F) P - Ta IO - Ta IO (mA) 20 250 200 Allowable output current Allowable power dissipation P (mW) 300 150 100 50 0 -20 0 20 40 60 80 16 12 8 4 0 -20 100 0 Ambient temperature Ta (C) VOL - IOL 80 100 (typ.) 1000 VOL (mV) Low level output voltage VOL (V) Low level output voltage 60 VOL - Ta (typ.)
