CD74HC157M96 datasheet by Texas Instruments

CD74HC157M96 Frequently Asked Questions (FAQs)

• What is the maximum frequency of operation for the CD74HC157M96?
  The maximum frequency of operation for the CD74HC157M96 is 25 MHz.
• How do I ensure signal integrity when using the CD74HC157M96?
  To ensure signal integrity, use a low-impedance PCB design, minimize trace lengths, and use termination resistors if necessary. Also, ensure that the power supply is clean and well-regulated.
• Can I use the CD74HC157M96 in a 5V system?
  Yes, the CD74HC157M96 is compatible with 5V systems. However, ensure that the input signals are within the recommended voltage range (VCC - 1.5V to VCC + 0.5V) to prevent damage to the device.
• How do I handle the enable inputs (E1 and E2) when not in use?
  When not in use, tie the enable inputs (E1 and E2) to VCC or GND, depending on the desired state. Leaving them floating can cause unpredictable behavior.
• What is the recommended power-on sequence for the CD74HC157M96?
  The recommended power-on sequence is to apply power to VCC before applying input signals. This ensures that the device is properly initialized and prevents damage.
