The MC10E/100E/300E457FNR2G is a member of MECL 10E family of logic products. It is a three-state logic device that combines a multiplexer, switch, and decoder in one package. This device offers numerous benefits to designers including reduced board space and faster signal propagation. This article will explain the applications of the MC10E457FNR2G and its working principle.

Applications

The MC10E457FNR2G is primarily used for logic and signal applications. The three-state feature makes it an ideal solution for applications such as data bus multiplexing and address line sharing. Multiple MC10E457FNR2Gs can also be connected together to form larger integral circuits, allowing designers to build a variety of complex logic functions. The device is also useful in applications such as data bus arbitration and shifting, which require fast signal propagation.

Working Principle

The MC10E457FNR2G is a three-state logic device that works by combining a multiplexer, switch, and decoder into one package. The device has two enable inputs, E2 and E3, that control the output selection. When both enable inputs are low, the device will output its data input, D. When only one of the enable inputs is high, the device will output the high enable input. When both enable inputs are high, the device will output a high impedance state, effectively disabling the device.

The device also has an E4 input that can be used to override the E2 and E3 inputs. When E4 is low, the device will output its data input, D, regardless of the states of E2 and E3. This can be used to control multiple devices on a single signal line.

The output of the device can also be used in logic applications. The output of the device can be connected to an OR gate, allowing multiple signals to be combined. This can be used to combine multiple signals and can greatly reduce the required number of logic gates.

The MC10E457FNR2G is a versatile device that is useful in a variety of applications. Its ability to combine a multiplexer, switch, and decoder into one package makes it a valuable tool in the design of a variety of logic and signal applications.
