4 线至 10 线 BCD 至十进制解码器
Technology Family HC
Number of channels (#) 1
Operating temperature range (C) -55 to 125
Rating Military
ICC (Max) (uA) 160
  • Wide Operating Voltage Range of 2 V to 6 V
  • Outputs Can Drive Up To 10 LSTTL Loads
  • Low Power Consumption, 80-μA Max ICC
  • Typical tpd = 14 ns
  • ±4-mA Output Drive at 5 V
  • Low Input Current of 1 μA Max
  • Full Decoding of Input Logic
  • All Outputs Are High for Invalid BCD Conditions
  • Also for Applications as 3-Line to 8-Line Decoders

These decimal decoders consist of eight inverters and ten 4-input NAND gates. The inverters are connected in pairs to make BCD input data available for decoding by the NAND gates. Full decoding of valid input logic ensures that all inputs remain off for all invalid input conditions.
