SN74LS257BD Frequently Asked Questions (FAQ)

  • The maximum frequency of operation for the SN74LS257BD is typically around 30-40 MHz, but this can vary depending on the specific application, supply voltage, and output loading.

  • To ensure proper operation, the SN74LS257BD should be powered from a stable 5V supply with a minimum of 10uF decoupling capacitor between VCC and GND, and additional decoupling capacitors may be required depending on the specific application and layout.

  • The SN74LS257BD can sink up to 16mA and source up to 0.5mA per output, but this can vary depending on the specific application and output loading.

  • Unused inputs on the SN74LS257BD should be tied to a valid logic level (either VCC or GND) to prevent floating inputs and ensure proper operation.

  • The SN74LS257BD is a 5V device and is not directly compatible with 3.3V logic. However, it can be used with 3.3V logic with proper level shifting and voltage translation.
