SN54S140J datasheet by Texas Instruments

SN54S140J Frequently Asked Questions (FAQs)

• What is the maximum operating frequency of the SN54S140J?
  The maximum operating frequency of the SN54S140J is 40 MHz.
• Can I use the SN54S140J in a 5V system?
  Yes, the SN54S140J is designed to operate from 4.5V to 5.5V, making it suitable for 5V systems.
• How do I handle the output enable (OE) pin?
  The output enable (OE) pin is active-low, meaning it should be connected to GND to enable the outputs. Connect it to VCC to disable the outputs.
• What is the propagation delay of the SN54S140J?
  The typical propagation delay of the SN54S140J is 10 ns, but it can vary depending on the operating conditions and load capacitance.
• Can I use the SN54S140J in a 3.3V system?
  No, the SN54S140J is not designed to operate at 3.3V. It requires a minimum supply voltage of 4.5V.
