CD4512BNSR datasheet by Texas Instruments

CD4512BNSR Frequently Asked Questions (FAQs)

• What is the maximum clock frequency that the CD4512BNSR can handle?
  The CD4512BNSR can handle clock frequencies up to 10 MHz, but it's recommended to limit it to 5 MHz for reliable operation.
• How do I ensure that the CD4512BNSR is properly reset during power-up?
  To ensure proper reset, connect the RST pin to VCC through a 1kΩ resistor and a 10nF capacitor to ground. This will provide a clean reset signal during power-up.
• What is the recommended operating voltage range for the CD4512BNSR?
  The recommended operating voltage range for the CD4512BNSR is 4.5V to 5.5V, with a typical voltage of 5V.
• How do I interface the CD4512BNSR with a microcontroller?
  The CD4512BNSR can be interfaced with a microcontroller using a 4-bit or 8-bit bus. Connect the CD4512BNSR's data pins (D0-D3 or D0-D7) to the microcontroller's data bus, and the CD4512BNSR's clock pin (CLK) to the microcontroller's clock signal.
• What is the purpose of the LE (Latch Enable) pin on the CD4512BNSR?
  The LE pin is used to latch the data present on the data bus into the CD4512BNSR's internal registers. When LE is high, the data is latched, and when LE is low, the data is not latched.
