Texas Instruments 20-SOIC CD74HCT688MG4

The CD74HCT688MG4 is a Texas Instruments-manufactured 8-bit parallel magnitude comparator with enable input. It's part of the 74HCT logic family, designed for CMOS-TTL compatibility and operates with a voltage range of typically 2V to 6V. This IC comes in a 20-pin SOP (Small Outline Package) and compares two 8-bit words, outputting a match signal when both inputs are equal (P=Q). It offers low power consumption and fast propagation delay (e.g., 29ns at 6V), making it suitable for high-speed digital systems requiring comparison functionality.
