PT2270 is a remote control decoder paired with PT2260 or PT2262 utilizingCMOS Technology. It has 12 bits of tri-state address pins providing a maximumof 531,441 (or 312) address codes; thereby drastically reducing any code collisionand unauthorized code scanning possibilities. PT2270 is available in severaloptions to suit every application needs : variable number of data output pins, latchor momentary output type.When paired with PT2260, this encoder/decoder (PT2260 / PT2270) pair canoperate at very wide temperature range (-30oC ~ +70 oC). See also PT2260Product Specification Features. Thus, this very important feature enables yourEncoder/Decoder to operate under the worst environmental condition.
