Description

The W91510DN series ICs are Si-gate CMOS IC that provide the signals needed for either pulse or tone dialing. They feature 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 W91510DN series is fabricated using CMOS technology and thus provide good performance in low voltage, low power applications.
