DESCRIPTION
The M74HC147 is an high speed CMOS 10 TO 4
LINE
PRIORITY
ENCODER
fabricated
with
silicon gate C2MOS technology.
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 decimal zero
condition requires no input condition as zero is
encoded when all nine data lines are at high logic
level. All data inputs and outputs are active at the
low logic level.
All inputs are equipped with protection circuits
against static discharge and transient excess
voltage.
