It is generally accepted that there is no substitute. The
1.4511 chip is a chip specifically designed for nipet-driven drives, and there is no similar substitute widely used in the market. Some people will try to use other types of chips or modules to replace the 4511 chip, but the functions and application scenarios of these substitutes have great limitations, and can not completely replace the role of the 4511 chip. 3. Due to the large market demand for 4511 chips, manufacturers also have high barriers and technical strength, it is generally believed that no other chips or modules can completely replace 4511 chips at this stage.
1.4511 chip can be replaced by 74LS47, CD4511, CD4511BE and other chips.
2. Because these chips are BCD code converted to 7-segment digital tube display chips, with similar functions and characteristics.
3. When selecting a replacement chip, it is necessary to pay attention to its electrical parameters, pin definition and interface compatibility to ensure that the replaced circuit can work normally.
The 4511 chip is a BCD-7 segment nixie driver chip that can convert the BCD code into a 7-segment LED display. If you want to replace the 4511 chip, you can consider using other nixtube driver chips, such as CD4543, CD4513, CD4026, etc. These chips can also realize the display function of the BCD-7 segment LED digital tube. However, different chips have different electrical properties, functions and packages, and in order to ensure that the replacement chip can work properly, the circuit needs to be improved and adjusted appropriately.
1 can be replaced by AT89C51, performance and function are similar
The 4511 is a commonly used line integrated circuit chip, also known as a B-series device, consisting of four seven-segment nib drivers. Each driver contains an output pin corresponding to the seven-segment nixie, as well as a set of input pins for input control signals and bit codes. It can convert the input four bits into the corresponding seven digits on the digital tube. Therefore, it is commonly used in digital display and detection systems.
The 4511 chip can be replaced with 74LS47.
