74LV541DB,118 is a Dual 1-of-4 Decoder/Demultiplexer by NXP Semiconductors, which belongs to the Logic - Buffers, Drivers, Receivers, Transceivers category. Specifically, 74LV541DB,118 is a low-voltage CMOS decoder/demultiplexer integrated circuit that provides two independent 4-to-1 multiplexers with logical input buffers on all Data (D) inputs and all select (S) inputs. The device is designed for 2.7 V to 5.5 V VCC operation

Application Field

By providing four data inputs and selecting one of the data outputs with two select inputs, 74LV541DB,118 can be used as a simple decoder for routing digital signals. In addition, it can implement a buffered address demultiplexer and bus splitter functions, making it suitable for applications in the industry and consumer field. It is especially suitable for space-constrained applications where the small-footprint of this device is an advantage.

Working Principles

74LV541DB,118 is both a decoder and demultiplexer. In decoder mode, the four data inputs can offer eight different combinations so that when any one of the eight combinations is applied to the data inputs, one of four outputs will be selected and the other outputs will be forced to be a low logic state. While in demultiplexer mode, with two control inputs to select one of the data inputs, one of four outputs will be selected according to the data input.

The outputs are capable of driving up to 15LSTTL loads directly, and can provide the necessary driving capability for standard and high capacitive loads. In addition, the output buffer has active pull up for more active logic high level output. The device has an active low enable input (E) that is used to enable and disable the device.

Conclusion

Overall, the 74LV541DB,118 is a low-voltage CMOS decoder/demultiplexer integrated circuit that offers two independent 4-to-1 multiplexers and is suitable for the industry and consumer field. It is available in a space-saving Ultra Thin Small Outline Plastic (UT-SOP) package and other package options.
