MM74HCT138MX

 

General Description
The MM74HCT138 decoder utilizes advanced silicon-gate CMOS technology, and are well suited to memory address decoding or data routing applications. Both circuits feature high noise immunity and low power consumption usually associated with CMOS circuitry, yet have speeds comparable to low power Schottky TTL logic.
The MM74HCT138 have 3 binary select inputs (A, B, and C). If the device is enabled these inputs determine which one of the eight normally HIGH outputs will go LOW. Two active LOW and one active HIGH enables (G1, G2A and G2B) are provided to ease the cascading decoders.
The decoders’ output can drive 10 low power Schottky TTL equivalent loads and are functionally and pin equivalent to the 74LS138. All inputs are protected from damage due to static discharge by diodes to VCC and ground.

Electronic components are the basic building blocks of electronic circuits and are used to construct

various circuits that enable electronic products to perform various functions. The following are common

electronic components and their main functions:

1. Capacitor: used for storing charge, smoothing voltage, filtering, delaying, etc.
2. Resistor: used for limiting current, changing voltage, dividing voltage, regulating current, etc.
3. Diode: used for rectification, voltage stabilization, switching, etc.
4. Transistors such as thyristors and triodes: used for signal amplification, current control, switching, etc.
5. Integrated circuits (ICs): integrate multiple electronic components to achieve complex circuit functions.
6. Sensors: convert various physical quantities into electrical signals, such as temperature, humidity, light intensity, pressure, etc.

Electronic components are widely used in various electronic products such as computers, mobile phones,

televisions, audio, automotive electronics and more. Their function is to transmit, process and convert signals in

the circuit to provide the foundation for electronic products to perform various functions.
