CD4518BEE4 datasheet by Texas Instruments

CD4518BEE4 Frequently Asked Questions (FAQs)

• What is the maximum clock frequency that the CD4518BEE4 can handle?
  The CD4518BEE4 can handle clock frequencies up to 64 kHz, but it's recommended to operate it at a maximum frequency of 32 kHz for reliable operation.
• How do I ensure proper power sequencing when using the CD4518BEE4?
  To ensure proper power sequencing, apply power to the VCC pin before applying a clock signal to the CLK pin. Also, ensure that the VCC pin is stable before applying any input signals.
• What is the recommended operating voltage range for the CD4518BEE4?
  The recommended operating voltage range for the CD4518BEE4 is 4.5V to 5.5V, with a typical operating voltage of 5V.
• How do I handle the asynchronous reset (RST) input on the CD4518BEE4?
  The RST input is an active-low input that resets the counter to zero when pulled low. To handle the RST input, connect it to a pull-up resistor and a switch or a logic gate that can pull it low when needed.
• What is the purpose of the inhibit (INH) input on the CD4518BEE4?
  The INH input is used to inhibit the counting function of the CD4518BEE4. When the INH input is high, the counter is inhibited, and when it's low, the counter operates normally.
