CD4518BE datasheet by Texas Instruments

CD4518BE Frequently Asked Questions (FAQs)

• What is the maximum clock frequency that the CD4518BE can handle?
  The CD4518BE can handle clock frequencies up to 10 MHz.
• How do I ensure that the CD4518BE is properly reset during power-up?
  To ensure proper reset, connect the RST pin to a 10kΩ pull-up resistor to VCC and a 0.1μF capacitor to GND. This will ensure that the device is properly reset during power-up.
• What is the recommended operating voltage range for the CD4518BE?
  The recommended operating voltage range for the CD4518BE is 4.5V to 5.5V.
• How do I interface the CD4518BE with a microcontroller?
  The CD4518BE can be interfaced with a microcontroller using a serial interface. Connect the CLK pin to the microcontroller's clock output, the DIN pin to the microcontroller's data output, and the CE pin to the microcontroller's chip enable output.
• What is the purpose of the CE (Chip Enable) pin?
  The CE pin is used to enable or disable the CD4518BE. When CE is low, the device is enabled and data can be shifted in. When CE is high, the device is disabled and data cannot be shifted in.
