BCD to Decimal Decoders
General Description
These BCD-to-decimal decoders consist of eight inverters
and ten four-input NAND gates The inverters are connect-
ed in pairs to make BCD input data available for decoding
by the NAND gates Full decoding of input logic ensures
that all outputs remain off for all invalid (10 – 15) input condi-
tions
Features

Also for application as 4-line-to-16-line decoders 3-line-
to-8-line decoders
Y
All outputs are high for invalid input conditions
