Molex\'s FFB3904 product is a multiplexer bipolar transistor (BJT) array. The device has eight common-emitter NPN transistors integrated into a single package. Multiplexers can be used to route signals from multiple signal sources to a single destination and vice versa.

Its application field is diverse. It includes mixing, switching, amplification, and performing logic functions. This multiplexer array is well suited to audio applications, power amplifiers, and automotive electronics. It is also used in general purpose switching and signal routing applications. A few examples include motor control, digital/analog signal switching, power control, and industrial control systems.

The FFB3904 is a versatile, space-saving multiplexer array. It combines eight performance NPN transistors into a single package. Its industry standard SC-74A package contains the necessary components to construct the more common BJT multiplexer applications.

The FFB3904 array has four separate high-power NPN transistors. Each is rated for up to 0.8 Amps continuous current. The supply voltages are between 5 and 16 volts, depending on the application. The electrical characteristics are well matched across all four transistors, which helps to ensure uniform performance.

The working principle of the FFB3904 is rooted in the basics of transistor circuits. The BJT transistors are either on (saturated) or off (cut-off) depending on the applied base current. By controlling the current applied to the base, the current flowing through the collector-emitter junction can be switched. The collector is connected to the output, while the emitter is connected to the ground.

The FFB3904 provides convenience and flexibility to applications that require multiplexers. Each of the four pairs of transistors can be separately configured as a multiplexer with a single source and multiple destinations. In addition, the device is designed for use in high-power applications, making it suitable for a wide range of applications.

In summary, the Molex FFB3904 bipolar transistor (BJT) array combines eight NPN transistors in a single package offering the convenience and flexibility of multiplexers. It is suitable for applications in audio, power amplifiers, automotive electronics, motor control, and industrial control system applications. The working principle of the FFB3904 array involves controlling the current supplied to the base in order to control the current flowing through the collector-emitter junction.
