SN75ALS164DW datasheet by Texas Instruments

SN75ALS164DW Frequently Asked Questions (FAQs)

• What is the maximum operating frequency of the SN75ALS164DW?
  The maximum operating frequency of the SN75ALS164DW is 100 MHz, but it can be used at higher frequencies with proper termination and signal conditioning.
• How do I properly terminate the outputs of the SN75ALS164DW?
  The outputs of the SN75ALS164DW should be terminated with a 50-ohm resistor to VCC or GND, depending on the logic level, to ensure proper signal integrity and to prevent signal reflections.
• Can I use the SN75ALS164DW in a 3.3V system?
  Yes, the SN75ALS164DW can be used in a 3.3V system, but the input voltage threshold may be higher than expected due to the device's 5V-tolerant inputs. Ensure that the input signals meet the minimum input voltage threshold specified in the datasheet.
• How do I handle the power-up and power-down sequencing of the SN75ALS164DW?
  The power-up and power-down sequencing of the SN75ALS164DW should be controlled to prevent unwanted output transitions. Ensure that the VCC supply is stable before applying input signals, and that the input signals are stable before powering down the device.
• What is the maximum capacitive load that the SN75ALS164DW can drive?
  The maximum capacitive load that the SN75ALS164DW can drive is approximately 100 pF, but this can be affected by the operating frequency, signal amplitude, and PCB layout. Ensure that the capacitive load is within the recommended range to prevent signal degradation.
