4-Line To 10-Line Decoders (1 of 10) - SN74HC42
Datasheet
 

Description

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.

Features

  • 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
