The 74HC42 is a BCD-to-decimal decoder IC in DIP-16 (through-hole) package, designed for digital decoding and display driver applications in Pakistan. This CMOS logic integrated circuit converts 4-bit binary-coded decimal (BCD) input into 10 active-low decimal outputs, providing reliable decoding for seven-segment displays, multiplexers, and digital control systems. The DIP-16 package is ideal for breadboard prototyping and through-hole PCB assembly.
