MC10EP105FAR2 Application Field and Working Principle

The Multi-Function, Configurable, MC10EP105FAR2 is a CMOS Logic IC aimed at providing general purpose logic with selectable slew rates, high drive capability and low quiescent current. This IC integrates two independent 3-state buffer stages, each providing two directions of logic, for 4-bit bidirectional logic. This device also presents two user-specified logic functions occupying four ports, offering logic designers the ability to tailor the logic on the chip to their needs.

Applications

The MC10EP105FAR2 is a versatile IC which is best suited for applications which demand high logic speeds, low power consumption and extremely low quiescent current/standby current. It can also be used in memory and bus-interface applications. In these applications, an open-drain network composed of the MC10EP105FAR2 is capable of driving multiple loads without encountering excessive current loading.

The MC10EP105FAR2 is easily programmable so it can be configured to support a vast array of logic functions. In addition to being used in general logic applications, its programmability allows it to be used in interfacing systems which require logic decoding/encoding and memory control. It can also be used in timing functions such as Pulse Width Modulation (PWM) and other complex applications requiring multiple logic functions.

Working Principle

The MC10EP105FAR2 is designed to provide excellent logic interface and speed. It consists of two sections, the internal logic and the output buffers. The internal logic is composed of two logic cells and two external input ports. The logic cells provide the logic to control four external ports and are programmed by means of the two input ports. The logic cells can also be used for other logic functions such as memory and bus-interface applications.

The output buffers are responsible for driving up to four loads at the same time, with a total output current of 3.5mA. The output buffers also feature a slew rate adjustable control pin, allowing users to define the switching speed of the buffer.

Finally, the MC10EP105FAR2 also incorporates a unique low-power feature to reduce quiescent current. This feature includes an internal standby control pin, allowing the IC to be placed in a low-power state when not in use. This reduces the current consumption of the IC to only 0.5mA, an incredibly low value compared to other CMOS Logic ICs.

Conclusion

In summary, the MC10EP105FAR2 is a highly capable, multi-function, configurable Logic IC. It offers high speeds, low power consumption and the ability to be tailored to specific logic needs. This makes it an excellent choice for interfacing applications and memory control systems.
