The MM74HC688WMX is an 8-bit magnitude comparator integrated circuit (IC) manufactured by AMI Semiconductor/ON Semiconductor. It belongs to the 74HC series of logic devices and is designed to compare two 8-bit digital inputs, providing an active-low output signal when the two inputs are equal.
The IC is packaged in a 20-pin SOIC (Small Outline Integrated Circuit) with a width of 7.50mm, making it suitable for surface-mount applications. It operates within a wide temperature range of -40°C to 85°C and is compliant with the RoHS (Restriction of Hazardous Substances) directive, indicating its lead-free and environmentally-friendly construction.
The key features of the MM74HC688WMX include its ability to compare two 8-bit digital inputs and produce an active-low output signal when the inputs are equal. This functionality makes it useful in a variety of applications, such as data processing, control systems, and digital signal processing, where the comparison of digital values is required.
The IC has a low quiescent current of 8 microamperes (μA) and can operate on a supply voltage range of 2 to 6 volts, making it suitable for both low-power and high-power applications. The maximum propagation delay, which is the time it takes for the output to respond to a change in the input, is 30 nanoseconds (ns) when the supply voltage is 6 volts and the load capacitance is 50 picofarads (pF).
The MM74HC688WMX is compatible with other 74HC-series logic devices, allowing for seamless integration into existing designs. It is available in a Tape and Reel (TR) package, which is convenient for automated assembly processes.
As for equivalent or alternative models, there are several similar 8-bit magnitude comparator ICs available from other manufacturers, such as the 74HC688 from Texas Instruments, the SN74HC688 from Texas Instruments, and the 74LVC688 from various vendors. These devices may have slightly different specifications, packaging options, or additional features, but they generally serve the same purpose as the MM74HC688WMX.
