HEF4894BT,112 Frequently Asked Questions (FAQs)

  • The recommended operating voltage range for the HEF4894BT,112 is 4.5V to 15V, although it can operate down to 3V with reduced performance.
  • To ensure proper power-on and power-off, Nexperia recommends using a power-on reset (POR) circuit or a voltage supervisor to guarantee a clean power-up sequence.
  • The maximum frequency of operation for the HEF4894BT,112 is 10 MHz, although it can operate at higher frequencies with reduced performance and increased power consumption.
  • The output enable (OE) pin should be connected to VCC or a logic high signal to enable the outputs. Leaving OE unconnected or floating can cause unpredictable behavior.
  • Nexperia recommends using a symmetrical layout, keeping the input and output traces short and away from each other, and using a solid ground plane to minimize noise and EMI.
