CD4511BF datasheet by Texas Instruments

CD4511BF Frequently Asked Questions (FAQs)

• What is the maximum clock frequency that the CD4511BF can handle?
  The CD4511BF 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 CD4511BF is properly reset during power-up?
  To ensure proper reset, connect the RST pin to VCC through a 1 kΩ resistor and a 10 nF capacitor to ground. This will provide a clean reset signal during power-up.
• What is the recommended operating voltage range for the CD4511BF?
  The recommended operating voltage range for the CD4511BF is 4.5 V to 5.5 V, with a typical voltage of 5 V.
• How do I interface the CD4511BF with a microcontroller?
  The CD4511BF can be interfaced with a microcontroller using a serial interface, such as SPI or I2C. The microcontroller can send clock, data, and control signals to the CD4511BF to program the display.
• What is the maximum number of displays that can be driven by a single CD4511BF?
  A single CD4511BF can drive up to 8 seven-segment displays, with each display having a maximum of 4 digits.
