SN74GTLPH1645DGGR datasheet by Texas Instruments

SN74GTLPH1645DGGR Frequently Asked Questions (FAQs)

• What is the maximum operating frequency of the SN74GTLPH1645DGGR?
  The maximum operating frequency of the SN74GTLPH1645DGGR is 250 MHz.
• How do I ensure signal integrity when using the SN74GTLPH1645DGGR?
  To ensure signal integrity, use a low-impedance PCB design, minimize trace lengths, and use termination resistors as needed. Also, follow the recommended layout guidelines in the datasheet.
• Can I use the SN74GTLPH1645DGGR in a 3.3V system?
  Yes, the SN74GTLPH1645DGGR is compatible with 3.3V systems. However, ensure that the input voltage (VCC) is within the recommended range of 3.0V to 3.6V.
• How do I handle power sequencing when using the SN74GTLPH1645DGGR?
  To ensure proper power sequencing, power up the VCC pin before applying input signals, and power down the VCC pin after removing input signals.
• What is the recommended termination scheme for the SN74GTLPH1645DGGR?
  The recommended termination scheme is to use a series resistor (Rs) and a parallel terminator (Rt) at the far end of the transmission line. The values of Rs and Rt depend on the specific application and transmission line characteristics.
