The CD4532BE is a dual 4-to-1 data selector/multiplexer, or data selector/multiplexer/decoder. It is an essential component for switching, multiplexing and decoding of digital signals. It is advantageous in a wide range of logic applications, including computer and digital systems, data communications and instrumentation. This article will discuss the application field and working principle of the CD4532BE.

Application Field of the CD4532BE

The CD4532BE is most commonly used as a data selector/multiplexer, where it can select and multiplex data among 4 different input signals. The input signals are selectable via two of the four control inputs, A and B. Once activated, the selected input can be sent to a single output line. The device can also serve as a decoder and can recognize binary input codes and provide corresponding output signals. This makes it useful for encoders or for applications that require data and address decoding. In addition, the device is also capable of distributing or combining digital signals, making it suitable for use in computers and other complex digital systems.

The CD4532BE is also well suited for applications where timing is critical. It has an active low enable input that enables or disables the outputs when disabled. This allows for fast switching of the outputs, making it suitable for use in timing circuits. The device also has a large propagation delay (approximately 15ns) which ensures that the signals arrive in the correct respective timing. The CD4532BE also features a low power consumption, making it an ideal component for power efficient applications.

Working Principle of the CD4532BE

The CD4532BE is an integrated circuit built with semiconductors. The device works by applying two control inputs (A and B) to the four data inputs. Depending on the logic state of the two inputs, one of the four data inputs will be selected and transferred to the output line. In this way, the device can select between four different inputs, multiplexing the selected data to a single output. The device can also function as a decoder, where it can be used to decode 4-bit binary input codes into 4-bit output codes.

The device is powered with a single supply voltage and operates over the common voltage range of 3V to 15V. It requires a minimum input current of 1.5µA at the control inputs and a minimum output current of 3µA. The device has an active low enable input, which can be used to enable or disable the outputs. When the enable input is low, all the outputs are disabled, otherwise the outputs will follow the inputs.

The CD4532BE operates with high speed and low power consumption. It features a propagation delay of approximately 15ns, making it suitable for timing circuits. The device also features low power consumption, ensuring it is well suited for power efficient applications. The device also has a high noise immunity, providing maximum protection against EMC interference.

Conclusion

The CD4532BE is a dual 4-to-1 data selector/multiplexer, or data selector/multiplexer/decoder. It is an essential component for switching, multiplexing and decoding of digital signals. It is advantageous in a wide range of logic applications, including computer and digital systems, data communications and instrumentation. The device operates with high speed and low power consumption and its low noise immunity allows for maximum protection against EMC interference.
