SN74LS148DR datasheet by Texas Instruments

SN74LS148DR Frequently Asked Questions (FAQs)

• What is the maximum operating frequency of the SN74LS148DR?
  The maximum operating frequency of the SN74LS148DR is 25 MHz.
• Can I use the SN74LS148DR in a 3.3V system?
  No, the SN74LS148DR is a 5V device and is not compatible with 3.3V systems. You may need to use a level translator or a different device that is compatible with 3.3V systems.
• How do I handle the output enable (OE) pin?
  The output enable (OE) pin is active-low, meaning that the outputs are enabled when OE is low (connected to GND) and disabled when OE is high (connected to VCC).
• What is the propagation delay of the SN74LS148DR?
  The propagation delay of the SN74LS148DR is typically around 10-15 ns, but this can vary depending on the operating conditions and load capacitance.
• Can I use the SN74LS148DR in a high-temperature environment?
  The SN74LS148DR is rated for operation from 0°C to 70°C. If you need to operate the device in a higher temperature environment, you may need to derate the device or use a different device that is rated for higher temperatures.
