Integer multiplexing is an important building block for many digital systems. It allows the user to select between different logic inputs and output a single logic signal. The CY74FCT157ATDR is a low-power, low-noise four-input multiplexer/demultiplexer that can be used for such applications.The CY74FCT157ATDR is a single-ended device in the 74FCT family of digital CMOS integrated circuits. It is a high-performance device that is ideal for applications where power and noise are of concern. It is pin and functionally compatible with the TTL 74F157 and is available in 16-pin plastic DIP and SOIC packages. The device uses two externally controlled select input signals, S0 and S1, to select four logic inputs and one output signal.The select inputs, indicated by S0 and S1 on the device, are asserted low (to ground) in order to select a single input out of the four available. The output signal is high when the selected input is high, and low when the selected input is low. The device is designed so that when both select lines are low, the output is low no matter what the inputs are. This allows for the use of the multiplexer as a simple logic gate or switch when desired.In order to use the multiplexer correctly, first determine the logic levels that need to be used. Logic levels can be TTL (0-5 volts) or CMOS (L-H levels). Once the logic levels have been established, the S0 and S1 inputs can be connected to the logic level desired. In most cases a control logic or micro-processor will be used to determine the logic level of the S0 and S1 inputs. The multiplexer can also be used as a de-multiplexer by setting one of the select signals high and the other low.Once the CY74FCT157ATDR is correctly connected to the logic levels, power can be applied and the output will reflect the input selected by the S0 and S1 lines. Care must be taken to ensure that the logic levels present at the input and output nodes are within the operational range of the multiplexer. The device also has low-power consumption with a typical power supply of 1.7V and a maximum power supply of 3.6V.In conclusion, the CY74FCT157ATDR is an ideal solution for applications where low power and noise are of concern. This device provides a high-performance, low-noise, low-power multiplexer/demultiplexer that can be used to select between four logic inputs and one output signal, making it an essential building block in many digital systems.
