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 M54/74HC147 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 decimal zero condition requires no input condition as zero is encoded when all nine datalinesare at high logic level. Alldata input and outputs are active at the low logic level. All inputs are equipped with protection circuits against static discharge and transient excess voltage.
