TPS853 2008-07-10 5 handling precautions insert a bypass condenser of up to 0.1 f between v cc and gnd near the device to stabilize the power supply line. it takes at least 200 ms when v cc /v stb are turned on at the same time or 100 ms when v stb is turned on after v cc is on for the internal circuit to stab ilize. during this time the output sign al is unstable. please do not use the unstable signal as the output signal. moisture-proof packing to avoid moisture absorption by the re sin, the product is packed in an aluminum envelope with silica gel. since the optical characterist ics of the device can be affected duri ng soldering by vaporization resulting from prior absorption of moisture and they should therefore be stor ed under the following conditions: 1. if the aluminum bag has been stored unopened temperature: 5 to 30 c relative humidity: 90% rh (max) time: 6 months 2. if the aluminum bag has been opened temperature: 5 to 30 c relative humidity: 70% rh (max) time: 168 h 3. baking should be conducted within 72 h after the humidity indicator shows > 30% or the bag seal date is over 6 months. the number of baking should be once. if the baking is conducted repeatedly, it may affect the peel-back force and cause a problem for mounting. baking condition: 60 5 c, 12 to 24 h storage period: 12 months from the seal date on the label 4. when the photointerrupter is baked, pr otect it from electrostatic discharge. 5. do not toss or drop to avoid damaging the moisture-proof bag. mounting precautions TPS853 uses a clear resin, and delicate handling is necessary for it. the characteristic change or the product might be damaged by the handling method of mounting. please note the following and handle the product. (1) do not apply stress to the resin at high temperat ure. time until the product returns at the normal temperature after mounting of the reflow is different according to the mounting substrate and the environment. please do not give the stre ss with heat remained in the product. (2) the resin part is easily scratched, so avoid friction with hard materials. (3) when installing the assembly boar d in equipment, ensure that th is product does not come into contact with other components. (4) please confirm the heat contraction of the substr ate of the reflow mounting doesn't influence the product. the load is given to the product by mo unting that the heat contraction is large on the substrate and the installation positi on of the substrate. please note that the characteristic changes or the product might be damaged.
