Overview
TECHNICAL DATA PULSE DIALER WITH REDIAL The IL5851 is a monolithic CMOS integrated circuit which uses an inexpensive RC oscillator for its frequency reference and provides all the features required for implementing a pulse dialer with 32 digit redial.
• Wide operating voltage range (2.
0~6.
0V) • Low power dissipation • Use either a standard 2 of 7 matrix keyboard with negative true common or the inexpensive form A-type keyboard • Make/Break ratio can be selected • Redial with * or # • Continuous MUTE • Power up clear circuitry on chip • 10 pps/20 pps can be selected IL5851 ORDERING INFORMATION IL5851N Plastic TA = -20° to 70° C LOGIC DIAGRAM PIN ASSIGNMENT com 1 ww.
