The NC7SZ384P5 is a high-speed, low-power triple-input CMOS logic Multiplexer. It has three pins, namely, SEL(0,1,2) input pins and two output pins Z and G. It provides an Selects/Inverts/Does NOT operation instead of a more conventional Selects/Inverts/Retains function. This is an important feature for both logic and noise immunity improvement. This device also comes with a static Protection Mode feature for power-down designs. The NC7SZ384P5 can be used for selecting among three binary inputs and drive one of them to a logic 0 or 1, with output enable control.

Application Field

The NC7SZ384P5 is a versatile Multiplexer, used in many applications. It can be used to build digital logic functions that require multiplexing such as coded memory decoders in microcontrollers, data selectors/combiners and multiplexers, sequential logic, bus expansion and address blaancing to name a few. This device can handle various logic levels, has fast propagation delay and is suitable for high voltage applications. It can also be used in control systems, pattern recognition, digital signal processing and data transmission where it can be used to control flow of data while preventing multiplexing timeouts.

Working Principle

The working principle of the NC7SZ384P5 consists of two stages. In the first stage, the SEL (0,1,2)selects the desired logic input when driven low. The second stage is the inversion stage, which further selects and inverts the logic inputs if Enable is high. The outputs of the Multiplexer are driven low or high depending on the logic levels at the inputs. The device can be used to drive two distinct outputs, a logic 0 and a logic 1, depending on the Select (0,1,2) lines. The device operates on a single supply voltage and has an enable pin that controls the output. It has an active low logic, meaning that logic 0 represents the asserted state, while logic 1 represents the non-asserted state. When the Enable is driven high, the selected signal is inverted and driven to the output.

Conclusion

The NC7SZ384P5 is a high-speed, low-power triple-input CMOS logic Multiplexer which can be used to build digital logic functions that require multiplexing. It performs a Selects/Inverts/Does NOT operation and can be used for selecting among three binary inputs and drive one of them to a logic 0 or 1, with output enable control. This device can also handle various logic levels, has fast propagation delay and is suitable for high voltage applications. This Multiplexer is an ideal component for application in control systems, pattern recognition, digital signal processing and data transmission.
