74HC147 Decimal to BCD Priority Encoder SMD IC
The 74HC147 is a Decimal to BCD (Binary Coded Decimal) Priority Encoder in an SMD (Surface Mount Device) package, designed to convert a decimal input (0 to 9) into a 4-bit BCD output. It is a high-speed CMOS device that operates within a voltage range of 2V to 6V, offering versatility in various digital systems. This IC has 10 inputs (I0 to I9) and a 4-bit output (D0 to D3) which corresponds to the binary representation of the highest active input. It also features a carry-out (C) signal, indicating whether the input is greater than or equal to 8. The 74HC147 includes a priority function, which ensures that only the highest-order input is encoded when multiple inputs are active. The IC uses active-low logic, meaning that the lowest priority input (I0) will be given priority over higher inputs, and the corresponding binary output will represent the highest active input. The 74HC147 is TTL-compatible, making it easy to interface with other digital logic circuits. Its compact SMD package makes it well-suited for space-constrained applications such as handheld devices, remote controls, and other consumer electronics.
