CD54AC161F3A datasheet by Texas Instruments

CD54AC161F3A Frequently Asked Questions (FAQs)

• What is the recommended operating voltage range for CD54AC161F3A?
  The recommended operating voltage range for CD54AC161F3A is 4.5V to 5.5V, although it can operate from 3V to 5.5V with reduced performance.
• How do I handle the output enable (OE) pin in CD54AC161F3A?
  The output enable (OE) pin should be connected to GND to enable the outputs. If left floating, the outputs will be in a high-impedance state. It's recommended to tie OE to GND or VCC through a pull-down or pull-up resistor, respectively.
• What is the maximum clock frequency supported by CD54AC161F3A?
  The maximum clock frequency supported by CD54AC161F3A is 40 MHz, but it can operate at higher frequencies with reduced performance and increased power consumption.
• How do I ensure proper power sequencing when using CD54AC161F3A?
  To ensure proper power sequencing, apply power to VCC before applying any input signals. Also, ensure that the input signals are stable before applying the clock signal.
• What is the purpose of the VCC pin in CD54AC161F3A?
  The VCC pin is the power supply pin, which should be connected to a stable 5V power source. It's recommended to decouple VCC to GND with a 0.1uF capacitor to reduce noise and ensure reliable operation.
