The MM74HC251MTCX is an IC (integrated circuit) component that belongs to the MM74HC family of logic chips. It is a multiplexer with 8 channels or inputs, produced by the Fairchild Semiconductor Corporation. Here is a brief overview of its key features and functionalities:
1. 8-channel multiplexer: The MM74HC251MTCX offers 8 input channels, allowing it to select one of these inputs based on the control inputs.
2. Complementary outputs: It provides complementary outputs, which means that two output signals are generated - one is the actual output, and the other is the inverse of the output. These outputs are useful in various digital logic applications.
3. Non-inverting inputs: The component has non-inverting inputs, which means that when an input signal is received, the output signal does not experience inversion.
4. Select input lines: The chip includes three select input lines (S0, S1, and S2), allowing the user to control the multiplexer and select the desired input channel.
5. Output enable (OE) input: The MM74HC251MTCX includes an OE input that enables or disables the output of the chip. When OE is set to high, the output remains active, and when it is set to low, the output becomes inactive.
6. Wide operating voltage range: It operates within a wide voltage range, typically between 2 and 6 volts
