Part Number : 74HC42
Function : BCD to Decimal Decoder (1-of-10)
Package : SOIC 16 Pin Type
Maker : Philips Electronics
Pinouts : 
Description :
The 74HC42, 74HCT42 decoders accept four active HIGH BCD inputs and provide 10 mutually exclusive active LOW outputs. The active LOW outputs facilitate addressing other MSI circuits with active LOW input enables.
The logic design of the “42” ensures that all outputs are HIGH when binary codes greater than nine are applied to the inputs.
Features
• Mutually exclusive outputs
• 1-of-8 demultiplexing capability
• Outputs disabled for input codes above nine
• Output capability: standard
• ICCcategory: MSI
