BCD decoder1-of-10 decoderactive-low outputsHC CMOSSOIC-16

SN74HC42DR is a CMOS BCD-to-decimal decoder for selecting one of ten active-low outputs from a 4-bit BCD input. It is specified for 2 V to 6 V operation in a 16-pin SOIC package.

Best for

  • BCD-to-decimal output selection
  • Active-low logic decoding
  • Low-power CMOS control logic

Avoid if

  • An active-high decoded output is required without inversion
  • All 16 binary input combinations must select an output
  • Supply voltage is outside 2 V to 6 V

Check before use

  • Confirm D-C-B-A input wiring
  • Validate output current and load capacitance
  • Tie unused CMOS inputs to VCC or GND
