... It can perform line conversion and impedance matching, and supports both DTMF and keytone signals. The LA8515N’s low operating current reduces line load. Switching between the DTMF/keytone and voice circuits is controlled directly from a single MUTE input. The LA8515N is available in plastic 20-pin DIPs. ...
