Communication ICs

13-station repertory pulse / tone dialer

for telephone set

BU8329 / BU8329F

The BU8329 and BU8329F are large scale integrated circuits designed for use with telephones, with all of the

pulse / tone dialer functions necessary for basic telephone operation. These ICs are equipped with an internal repertory

memory containing 13 stations and 16 digits.

FApplications

Telephones

FFeatures

1) The chip includes both a pulse and tone dialer, mak-

ing 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,

: 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.
