NTE74141

NTE74141 Integrated Circuit TTL − BCD−to−Decimal Decoder/Driver 16−Lead DIP Type Package Description: The NTE74141 is a second−generation BDC−to−decimal decoder in a 16−lead DIP type package designed specifically to drive cold−cathode indicator tubes. This decoder demonstrates an improved capability to minimize switching transients in order to maintain a stable display. Full decoding is provided fo all possible input states. Fo binary inputs 10 through 15, all the outputs are off. Therefore the NTE74141, combined with a minimum of external circuitry, can use these invalid codes in blanking leading− and/or trailing−edge zeros in a display. The ten high−performance NPN output transistors have a maximum reverse current of 150 microamperes at 55 volts. Low forward−impedance diodes are also provided for each input to clamp negative−voltage transitions in order to minimize transmission−line effects. Power dissipation is typically 80 milliwatts. The NTE74141 is characterized for operation over the temperature range of 0 to +70C.
