Dual 1-of-4 Line Data Selector/Multiplexer IC - 74HC153

The 74HC Series 74HC153 IC's data selectors/multiplexers contains inverters and drivers to supply fully complementary, on-chip, binary decoding data selection to the AND-OR-invert gates. Separate strobe inputs are provided for each of the two four-line sections. 

The 74HC153 features independent enable inputs (nE) and common data select inputs (S0 and S1). For each multiplexer, the select inputs select one of the four binary inputs and routes it to the multiplexer output (nY). A HIGH on E forces the corresponding multiplexer outputs LOW. Inputs include clamp diodes

1.What is 4-input multiplexer?

  • Four data inputs D0, D1, D2 & D3, two selection lines S0 & S1, and one output Y comprise the 4x1 Multiplexer. The block diagram of a 4x1 Multiplexer is shown in the figure below. Based on the combination of inputs present at these two selection lines, one of these four inputs will be connected to the output.

2.What is the function of the 74HC153 IC?

  • The 74HC153 is a dual 4-input multiplexer that can route multiple inputs to a single output depending on the input selection. It is commonly used in digital circuits to switch between different data sources and to increase the number of input/output channels in a system.

3.Can the 74HC153 IC be used in conjunction with other digital circuits?

  • Yes, the 74HC153 IC can be combined with other digital circuits such as microcontrollers, memory devices, and logic ICs to create a flexible and expandable system design.
