SN74LVC112AD datasheet by Texas Instruments

SN74LVC112AD Frequently Asked Questions (FAQs)

• What is the maximum operating frequency of the SN74LVC112AD?
  The maximum operating frequency of the SN74LVC112AD is 100 MHz, but it can vary depending on the specific application and operating conditions.
• How do I ensure signal integrity when using the SN74LVC112AD in a high-speed design?
  To ensure signal integrity, use proper PCB layout techniques, such as impedance matching, signal routing, and decoupling. Additionally, consider using series termination resistors and/or parallel termination capacitors to reduce signal reflections and ringing.
• Can I use the SN74LVC112AD in a 3.3V system, and if so, what are the power supply requirements?
  Yes, the SN74LVC112AD can be used in a 3.3V system. The recommended power supply voltage range is 1.65V to 3.6V, with a typical operating voltage of 3.3V. Ensure that the power supply is stable and well-regulated to prevent voltage drops or spikes that may affect device operation.
• How do I handle power sequencing when using the SN74LVC112AD in a system with multiple power domains?
  When using the SN74LVC112AD in a system with multiple power domains, ensure that the power supplies are sequenced correctly to prevent voltage differences between domains. Typically, power up the domains in a sequence that ensures the SN74LVC112AD's power supply is stable before applying input signals.
• What is the recommended layout and routing for the SN74LVC112AD's output pins to minimize electromagnetic interference (EMI)?
  To minimize EMI, route the output pins as differential pairs, and keep them as short as possible. Use a ground plane or shield to isolate the output signals from other signals and noise sources. Additionally, consider using EMI-reducing components, such as common-mode chokes or EMI filters, in the output signal path.
