SN74LS125AN Frequently Asked Questions (FAQ)

  • The maximum frequency of operation for the SN74LS125AN is typically around 30-40 MHz, but this can vary depending on the specific application and operating conditions.

  • To ensure proper operation, the SN74LS125AN should be powered with a stable 5V supply, and decoupling capacitors (e.g. 0.1uF) should be placed as close as possible to the device to filter out noise and reduce electromagnetic interference (EMI).

  • The input voltage threshold for the SN74LS125AN is typically around 2.0V for a logic high and 0.8V for a logic low, but this can vary depending on the specific application and operating conditions.

  • While the SN74LS125AN is specified for 5V operation, it can be used in a 3.3V system with some limitations. However, the output voltage levels may not be compatible with 3.3V logic, and the device may not meet the required timing specifications.

  • To avoid bus contention, ensure that only one device is driving the bus at a time, and use bus-hold circuits or resistors to prevent backdrive currents. Additionally, consider using a bus arbiter or multiplexer to manage access to the bus.
