SN74LV393APW datasheet by Texas Instruments

SN74LV393APW Frequently Asked Questions (FAQs)

• What is the maximum clock frequency that the SN74LV393APW can handle?
  The maximum clock frequency of the SN74LV393APW is 100 MHz.
• How do I ensure that the SN74LV393APW is properly powered?
  The SN74LV393APW requires a power supply voltage (VCC) of 2.7V to 3.6V, and it is recommended to use a decoupling capacitor of 0.1uF to 1uF between VCC and GND to ensure proper power supply decoupling.
• What is the propagation delay of the SN74LV393APW?
  The propagation delay of the SN74LV393APW is typically around 10ns, but it can vary depending on the operating conditions and the specific application.
• Can I use the SN74LV393APW in a 5V system?
  No, the SN74LV393APW is not designed to operate at 5V. It is recommended to use a level translator or a voltage regulator to step down the voltage to the recommended operating range of 2.7V to 3.6V.
• How do I handle the output enable (OE) pin of the SN74LV393APW?
  The output enable (OE) pin is active-low, meaning that the outputs are enabled when OE is low (GND) and disabled when OE is high (VCC). It is recommended to tie OE to GND or VCC depending on the application requirements.
