Description
The LS256 is a monolithic integrated circuit in 16lead dual in-line and SO20 plastic packages to replacethe hybridcircuitin telephoneset.It workswith the same type of transdurcers for both transmitter and receiver (typically piezoceramic capsules, but DIP16 ORDERING NUMBERS : LS256B LS256D the devicecan work also with dynamicones).Many of its electrical characteristics can be controlled by means of external components to meet different specifications. In additionto the speech operation, the LS256 acts as an interface for the MF tone signal.
