Logic - Signal Switches, Multiplexers, Decoders

74CB3T3383DBQRE4 is a three-to-eight line decoder device with active low output and gated inputs. It is suitable for many applications in digital and communication circuits such as address decoding, data routing and selection, and interface and security in general.

Application Field

74CB3T3383DBQRE4 is primarily used in applications where two binary inputs need to be decoded into eight binary outputs. It is ideal for address decoding, data routing and selection and interface. It can also be used in security algorithms such as lock-and-key system, fingerprint sensors and face recognition.74CB3T3383DBQRE4 is also used in a variety of communication systems such as cellular network, computer-based communication networks and telecommunication systems. In such systems, it is utilized to decode binary signals into multiple binary outputs to establish useful connection between two or more devices. Moreover, 74CB3T3383DBQRE4 is also used in other digital circuits such as Digital-to-Analog circuits, Counter circuits and Voltage-Controlled Oscillator (VCOs) circuits. In such circuits, 74CB3T3383DBQRE4 is used to decode digital data into certain electrical signals such as voltage or current in order to create an analog output.

Working Principle

74CB3T3383DBQRE4 consists of two binary inputs - A and B. Each input can assume either a high (1) or low (0) voltage level. At the same time, there are 8 active-low outputs, O1 - O8. The input signals are decoded through the device\'s internal circuitry that translates the incoming binary signals into the corresponding outputs. When both input signals A and B assume logic high, the device produces 8 logic low outputs. Otherwise, only one output is logic low, depending on the combination of logic values at A and B.For example, when input A is logic high and input B is logic low, output O1 is logic low while outputs O2 - O8 are logic high. On the other hand, when both inputs assume logic low, all outputs are logic high.In addition, 74CB3T3383DBQRE4 comes with a feature called "gated inputs". It allows the inputs to be disabled to produce zero output state. This feature is important in preventing common logic error. To conclude, 74CB3T3383DBQRE4 is a three-to-eight line decoder device with active low output and gated inputs. It is suitable for many applications in digital and communication circuits such as address decoding, data routing and selection, and interface and security in general. It is also used in many other digital circuits such as D/A, counter and VCO circuits. With its gated inputs, the device can prevent common logic errors.
