SN74LS595DR datasheet by Texas Instruments

SN74LS595DR Frequently Asked Questions (FAQs)

• What is the maximum clock frequency for the SN74LS595DR?
  The maximum clock frequency for the SN74LS595DR is 30 MHz.
• Can I use the SN74LS595DR as a latch?
  Yes, the SN74LS595DR can be used as a latch by tying the clock input (CLK) high and using the serial input (SER) as the data input.
• How do I reset the shift register?
  The shift register can be reset by applying a low pulse to the reset input (RCLR). The reset input is active-low, so a low signal will reset the register.
• What is the propagation delay time for the SN74LS595DR?
  The propagation delay time for the SN74LS595DR is typically around 10-15 ns, but this can vary depending on the operating conditions and load capacitance.
• Can I use the SN74LS595DR with a 3.3V supply voltage?
  Yes, the SN74LS595DR is compatible with 3.3V supply voltage, but the output voltage will be limited to around 2.4V. It's recommended to use a voltage regulator or level shifter if you need a 3.3V output.
