The W91560DN series ICs are Si-gate CMOS ICs that provide the signals needed for either pulse or tone dialing. They feature 3 number memories and a 12/16-digit LCD driver for displaying telephone numbers and calling time. A real time clock is included to display the time of day. The W91560DN series is fabricated using CMOS technology and thus provide good performance in low voltage, low power applications.
The W91560DN series ICs are Si-gate CMOS devices designed for telephone dialing applications. They feature three 32-digit memories for one-touch direct repertory, a 12 or 16-digit LCD driver, and a real-time clock. The chips support both pulse and tone dialing modes and include features like pause, flash, and hold functions.
