Description
CD40147BMS 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. The CD40147BMS is func-
tionally similar to the TTL 54/74147 if pin 15 is tied low.
The CD40147BMS is supplied in these 16-lead outline
packages:
