74LS147 Dual Decimal to BCD Priority Encoder IC DIP-16 Package

The 74LS147 Dual Decimal to BCD Priority Encoder is a digital integrated circuit designed to convert decimal inputs into Binary-Coded Decimal (BCD) outputs based on priority. Packaged in a DIP-16 configuration, this IC provides efficient encoding for applications that require translating decimal inputs into BCD while prioritizing inputs with higher values if multiple inputs are active. This feature makes the 74LS147 particularly useful in applications such as keyboards, multiplexed displays, and similar input systems where priority selection is needed. This IC contains dual 10-line-to-4-line priority encoders, meaning it can encode two sets of decimal inputs independently into BCD outputs. Each encoder accepts up to 10 active low inputs (0–9), and the output is a 4-bit BCD code corresponding to the highest-priority input. For example, if inputs 3, 5, and 9 are active, the IC will output the BCD for 9, since it has the highest priority among the active inputs. This encoding scheme significantly reduces the need for external logic in circuits that handle multiple input lines with varying priorities.
