CD40147BNSRE4 belongs to the category of integrated circuits (ICs).
It is commonly used as a priority encoder in digital electronics.
CD40147BNSRE4 is available in a small-outline package (SOP) format.
The essence of CD40147BNSRE4 lies in its ability to encode multiple input lines into a smaller number of output lines based on their priority.
This product is typically packaged in reels or tubes, with a quantity of 2500 units per reel/tube.
CD40147BNSRE4 works by assigning priority to the input lines based on their position. The highest priority active input is encoded into a binary code on the output lines. The enable output (EO) pin enables cascading of multiple devices, allowing for larger encoding schemes.

Sure! Here are 10 common questions and answers related to the application of CD40147BNSRE4 in technical solutions:
Q: What is CD40147BNSRE4? A: CD40147BNSRE4 is a BCD-to-7-segment latch/decoder/driver IC, commonly used for converting binary-coded decimal (BCD) inputs into a 7-segment display output.
Q: What is the operating voltage range for CD40147BNSRE4? A: The operating voltage range for CD40147BNSRE4 is typically between 3V and 18V.
Q: How many BCD inputs does CD40147BNSRE4 have? A: CD40147BNSRE4 has four BCD inputs (A, B, C, and D), allowing it to accept a 4-bit BCD code.
Q: Can CD40147BNSRE4 drive common cathode or common anode displays? A: CD40147BNSRE4 is designed to drive common cathode displays. If you want to drive a common anode display, you would need additional external circuitry.
Q: What is the maximum frequency at which CD40147BNSRE4 can operate? A: CD40147BNSRE4 can typically operate at frequencies up to 6 MHz.
Q: How many 7-segment outputs does CD40147BNSRE4 provide? A: CD40147BNSRE4 provides 10 active-low 7-segment outputs (a through g, plus dp for the decimal point).
Q: Can CD40147BNSRE4 directly drive high-current loads? A: No, CD40147BNSRE4 is not designed to directly drive high-current loads. It requires additional external transistors or drivers for that purpose.
Q: What is the purpose of the latch in CD40147BNSRE4? A: The latch in CD40147BNSRE4 holds the BCD input values stable while the outputs are being decoded and displayed.
Q: Can CD40147BNSRE4 be cascaded to drive multiple 7-segment displays? A: Yes, CD40147BNSRE4 can be cascaded to drive multiple 7-segment displays by connecting the outputs of one IC to the inputs of another.
Q: Are there any specific precautions to consider when using CD40147BNSRE4? A: It is important to ensure that the power supply voltage does not exceed the specified maximum rating (typically 18V) to prevent damage to the IC. Additionally, proper decoupling capacitors should be used near the power supply pins to minimize noise and voltage fluctuations.
Please note that these answers are general and may vary depending on the specific datasheet and application requirements of CD40147BNSRE4.
