BU8874 General Description


The BU8874 and BU8874F are DTMF receiver ICs developed for use in telephone answering machines, and convert
16 different types of DTMF signals into 4-bit binary serial data. In addition to a compact 8-pin DIP (BU8874) package,
these receivers feature a wide dynamic range, eliminating the need for an external input amplifier. Expertise from a number of companies has been incorporated into these products to enable guard time control through a host microcontroller.

BU8874 Features

· Dynamic range of 45dB. (internal AGC)
· Power down mode.
· 4-bit binary serial data output.
· Guard time can be controlled through host microcontroller.
· Input pins equipped with hysteresis. (ACK pin)
· 4.19MHz crystal resonator can be used.
·8-pin DIP package. (BU8874)

BU8874 Typical Application

·Telephone answering machines
