... HANDFREE, LOCK AND HOLD FUNCTIONS GENERAL DESCRIPTION The W91810N is a series of tone/pulse switchable telephone dialers with 23 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 ...

... The HKS (hook switch) input is used to sense whether the handset is on-hook or off-hook. In on-hook state, HKS = 1: chip is in sleeping mode, no operation. In off-hook state, HKS = 0: chip is enabled for normal operation. HKS pin is pulled W91810N SERIES FUNCTION places the dialer SS places the dialer DD by internal resistor. DD ...
