Sir Aiman,

  Good day.

  We are currently looking for a chip for our LED price directory for gasoline station.

  The technician said the chip is malfunctioning every time we hook up the SPI ribbon cable

  it will turned  OFF the LED lights. He said the chip is at OFF STATE. He gave us 74HC24HD number.

  But noticed i can only find this on your site.

  Do you think this is the chip we need the 74HC244D,65274HC244D,652 and not 74HC24HD? Also what in the 74HC series

  can we use with same function. 4 DIGIT NUMERIC LED Display x 3 row, double face front & back.

  price display programmable via RF controller.

Thank you.

RJ
