BU8307CF General Description

The BU8307CS and BU8307CF are large scale integrated circuits with a pulse dialer and tone dialer integrated on a
single chip. These products are capable of dialing in either pulse or tone mode, and can redial up to 32 digits.

BU8307CF Features

` The chip includes both a pulse and tone dialer, making it possible to dial in either pulse or tone mode.
` A wide operating voltage range enables direct powering by line current. The voltage range guaranteed for both pulse and tone dialing is 2.5V to 5.5V.
` A built-in memory enables redialing of up to 32 digits. Note: In tone mode, the memory itself uses one digit, so please be aware that a maximum of 31 digits can be redialed.
` The chip conforms to the standards of Japan, America, Canada, England, Korea, Taiwan, and Australia.
` The V_DD power supply voltage is independent of the DTMF output level.
` There is little deviation in the frequency dividing for the DTMF output frequency. The maximum on the + side is + 0.15%, and on the - side is 0.08%.
