BU8329

The BU8329 is designed as one kind of 13-station repertory pulse / tone dialer that can be used in telephones. Features of the BU8329 are:(1)The chip includes both a pulse and tone dialer, making it possible to dial in either pulse or tone mode; (2)Wide operating voltage range of 2.0V to 5.5V; (3)Internal on-hook dial control function and hold control function; (4)A built-in memory enables redialing of up to 32 digits; (5)Repertory dial function: 3 stations and 16 digits for 1-touch and 10 stations and 16 digits for 2-touch; (6)Ceramic resonator of 3.579545MHz used; (7)Internal digital pause timer; (8)Internal flash function; (9)Compact SOP 24 pin and DIP 22 pin packages used.

The absolute maximum ratings of the BU8329 can be summarized as:(1)power supply voltage:7.0 V;(2)input voltage:Vss-0.3 to VDD+0.3 V;(3)output voltage 1:Vss-0.3 to VDD+0.3 V;(4)output voltage 2:Vss-0.3 to 7.0 V;(5)power dissipation:600 (DIP22) or 450 (SOP24) mW;(6)storage temperature:-55 to +125;(7)operating temperature:-10 to +60.
