SN74HC652DWR datasheet by Texas Instruments

SN74HC652DWR Frequently Asked Questions (FAQs)

• What is the maximum operating frequency of the SN74HC652DWR?
  The maximum operating frequency of the SN74HC652DWR is 30 MHz, but it can vary depending on the specific application and operating conditions.
• How do I handle the power-up and power-down sequencing of the SN74HC652DWR?
  It is recommended to power up the VCC pin before the input signals and power down the VCC pin after the input signals to prevent unwanted latch-up or damage to the device.
• What is the recommended termination scheme for the SN74HC652DWR?
  The recommended termination scheme for the SN74HC652DWR is to use a pull-up or pull-down resistor on the output pins to prevent floating inputs and ensure proper signal integrity.
• Can I use the SN74HC652DWR in a 5V system?
  Yes, the SN74HC652DWR is compatible with 5V systems, but it is recommended to use a voltage regulator or level shifter to ensure that the input signals are within the recommended operating range of 2V to 6V.
• How do I handle the thermal management of the SN74HC652DWR?
  The SN74HC652DWR has a maximum junction temperature of 150°C. It is recommended to use a heat sink or thermal pad to dissipate heat and ensure reliable operation.
