CD74HCT257M96 datasheet by Texas Instruments

CD74HCT257M96 Frequently Asked Questions (FAQs)

• What is the maximum frequency of operation for the CD74HCT257M96?
  The maximum frequency of operation for the CD74HCT257M96 is typically around 30-40 MHz, but it can vary depending on the specific application, supply voltage, and output loading.
• How do I ensure proper signal integrity and minimize signal skew when using the CD74HCT257M96?
  To ensure proper signal integrity and minimize signal skew, use short, matched trace lengths, and terminate the outputs with a suitable load impedance. Additionally, consider using a low-skew clock distribution network and ensure that the power supply is well-regulated and decoupled.
• Can I use the CD74HCT257M96 as a demultiplexer?
  Yes, the CD74HCT257M96 can be used as a demultiplexer by connecting the output enable (OE) input to the active-low state and using the A and B inputs to select the desired output.
• What is the recommended power-on reset sequence for the CD74HCT257M96?
  To ensure proper operation, it is recommended to power up the VCC supply before applying any input signals, and then apply the input signals after the power supply has stabilized.
• How do I handle unused inputs on the CD74HCT257M96?
  Unused inputs should be tied to a valid logic level (either VCC or GND) to prevent floating inputs and ensure proper device operation.
