DESCRIPTION The M54/74HC147 is a high speed CMOS 10 TO 4 LINE PRIORITY ENCODER fabricated in silicon gate C2MOS technology. It has the same high speed performance of LSTTL combined with true CMOS low power consumption. This device features priority encoding of the inputs to ensure that only the highest order data line is encoded. Nine input lines are encoded to a four line BCD output. The implied decima.
