... HANDFREE, LOCK AND HOLD FUNCTIONS GENERAL DESCRIPTION The W91F810N is a series of tone/pulse switchable telephone dialers with 23-falsh memory, keytone, hold, lock, mute, volume control and handfree dialing control features. These chips are fabricated using Winbond's high-performance CMOS technology and thus offer good performance in low- voltage, low-power operations ...
