Previously fabricated as a bipolar photo detector, the TEKS6400 is now CMOS-based to provide higher performance and lower power consumption. The device incorporates a Schmitt trigger output stage and a photo detector with an integrated daylight filter that is spectrum-matched to infrared (IR) emitters whose wavelength is 950 nm. It runs from power supply voltages between 2.5V and 5.5V and draws a supply current of 45 µA, making it suitable for battery-operated equipment. The detector is TTL- and CMOS-compatible with an open collector logic output that goes low when the IR light is on. The high sensitivity provides EMI suppression. The device operates over the industrial temperature range of -40°C to 85°C. The detector comes in a miniature plastic package measuring 5 mm x 5 mm x 2.65 mm high. An IR emitter (TSKS5400) in a compatible package is also available. Pricing in 100,000 piece quantities is $55 per 100 pieces. VISHAY INTERTECHNOLOGY INC., Malvern, PA. (203) 445-5501.
