Q & A
- Q: What is the primary function of the HEF4514BP,652?
A: The primary function of the HEF4514BP,652 is to act as a 1-of-16 decoder and demultiplexer.
- Q: What are the address inputs for the HEF4514BP,652?
A: The component has four binary weighted address inputs (A0 to A3).
- Q: How many outputs does the HEF4514BP,652 have?
A: The HEF4514BP,652 has 16 mutually exclusive outputs (O0 to O15).
- Q: What is the operating voltage range of the HEF4514BP,652?
A: The operating voltage range is from 4.5V to 15.5V.
- Q: What is the operating temperature range of the HEF4514BP,652?
A: The operating temperature range is from -40°C to 85°C.
- Q: Is the HEF4514BP,652 RoHS compliant?
A: Yes, the HEF4514BP,652 is lead-free and RoHS compliant.
- Q: What is the package type of the HEF4514BP,652?
A: The package type is 24-DIP (0.600", 15.24mm).
- Q: How does the latch enable input (EL) function in the HEF4514BP,652?
A: When EL is HIGH, the selected output is determined by the data on the address inputs. When EL goes LOW, the last data present at the address inputs are stored in the latches and the outputs remain stable.
- Q: What is the role of the active LOW enable input (E) in the HEF4514BP,652?
A: When E is LOW, the selected output, determined by the contents of the latch, is HIGH. At E HIGH, all outputs are LOW.
- Q: Can the HEF4514BP,652 be used as a demultiplexer?
A: Yes, the HEF4514BP,652 can be used as a demultiplexer where E is the data input and A0 to A3 are the address inputs.
