74LS147 - 10 to 4 Priority Encoder / 74HC147 DIP-IC

74LS147 / 74HC147 10-to-4 Priority Encoder IC

The 74LS147 and 74HC147 are high-performance 10-to-4 priority encoders, essential components for various digital logic applications. These integrated circuits efficiently convert 10 active-LOW inputs into a 4-bit binary-coded decimal (BCD) output. A key feature is their priority decoding capability, which ensures that only the highest-order data line is encoded when multiple inputs are active. This prevents ambiguity and streamlines data processing in complex systems. Housed in a convenient DIP package, these ICs are easy to integrate into breadboards and PCBs. They are widely used in data compression, keyboard encoding, and control systems. Both the LS and HC versions offer reliable performance, catering to different power and speed requirements. Choose the 74LS147 for standard TTL compatibility or the 74HC147 for CMOS logic levels and lower power consumption.
