TEX888H is a communication monolithic micro-computer integrated circuit. It is usually used as mobile phone control circuit in cordless telephone. Typical applied circuit diagram of mobile phone control which is composed of IC TEX888H is shown in picture 1. Note: When dialing the number, failure in dialing is easy to happen to the mobile. Under such circumstance, check whether the keys are short-circuits or not first, whether the conductive rubber resistance becomes larger or not, and whether the inside mobile is affected with damp or not. If password failure happens, you might emphasis on the check of the 18 pin of TEX888H and other exterior components. The possible reason of the malfunction can be judged by testing the dynamic or quiescent voltage of the pin.
