HD74HC42
BCD-to-Decimal Decoder
Description
Data on the four input pins select one of the 10 outputs corresponding to the value of the BCD number on
the inputs. An output will go low when selected, otherwise it remains high. If the input data is not a valid
BCD number all outputs will remain high.
Features
• High Speed Operation: t_pd = 13 ns typ (C_L = 50 pF)
• High Output Current: Fanout of 10 LSTTL Loads
• Wide Operating Voltage: V_CC = 2 to 6 V
• Low Input Current: 1 µA max
• Low Quiescent Supply Current: I_CC (static) = 4 µA max (Ta = 25°C)
