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: tpd = 13 ns typ (CL = 50 pF)
• High Output Current: Fanout of 10 LSTTL Loads
• Wide Operating Voltage: VCC = 2 to 6 V
• Low Input Current: 1 µA max
• Low Quiescent Supply Current: ICC (static) = 4 µA max (Ta = 25°C)
