The CD40147 CMOS encoder features priority encoding of the inputs to ensure that only the highest order data line is encoded.
Ten data input lines (0-9) are encoded to four line (8, 4, 2, 1) BCD.
The highest priority line is line 9.
All four output lines are logic 1 (VSS) when all input lines are logic 0.
All inputs and outputs are buffered, and each output can drive one TTL Low Power Schottky load.
