The M54/74HC147 is a high speed CMOS 10 TO 4
LINE PRIORITY ENCODER fabricated in silicon

MOS technology. It has the same high
speed performance of LSTTL combined with true
CMOS low powerconsumption.
This device features priority encoding of the inputs
to ensure that only the highest order data lineis en-
coded. Nine input lines are encoded to a four line
BCD output. The implied decimal zero condition re-
quires no input condition as zero is encoded when
allninedatalinesareathighlogiclevel.Alldatainput
and outputs are active at the low logic level. All in-
puts are equipped with protection circuits against
staticdischarge and transient excess voltage.
