SN74LS165ADR datasheet by Texas Instruments

SN74LS165ADR Frequently Asked Questions (FAQs)

• What is the maximum clock frequency that the SN74LS165ADR can handle?
  The maximum clock frequency of the SN74LS165ADR is 10 MHz.
• Can I use the SN74LS165ADR in a 3.3V system?
  Yes, the SN74LS165ADR is compatible with 3.3V systems, but the input voltage must not exceed 5.5V.
• How do I ensure that the data is properly latched in the SN74LS165ADR?
  To ensure proper latching, the clock signal should be high for at least 10 ns, and the data should be stable for at least 10 ns before the clock signal goes high.
• What is the maximum capacitance that the SN74LS165ADR can drive?
  The SN74LS165ADR can drive up to 100 pF of capacitance.
• Can I use the SN74LS165ADR in a system with multiple clock domains?
  Yes, the SN74LS165ADR can be used in systems with multiple clock domains, but care must be taken to ensure that the clock signals are properly synchronized and that the device is not subjected to clock skew.
