The SMD SN74HC147 is a 10-to-4 line priority encoder IC in SOP-16 (SOIC-16) surface-mount package, designed for decimal-to-BCD encoding and priority encoding applications in Pakistan. This CMOS logic integrated circuit encodes ten active-low inputs into a 4-bit BCD output with priority given to the highest-numbered input, providing reliable encoding for keyboard interfaces, data compression, and digital control systems. The SMD package enables compact PCB layouts and automated assembly for professional electronics manufacturing and prototyping.
