高速CMOS逻辑4位幅度比较 High-Speed CMOS Logic 4-Bit Magnitude Comparator
If you are looking for a more complex ALU, the magnitude comparator logic comparator from Texas Instruments can compare two or more bitwise operators, allowing for different operations to be performed. This logic comparator has an operating temperature range of -55 °C to 125 °C. This component will be shipped in tape and reel packaging for effective mounting and safe delivery. This non-inverting device has a typical operating supply voltage of 5 V. Its minimum operating supply voltage of 4.5 V, while its maximum is 5.5 V.
