The Texas Instruments 74HCT Series CD74HCT688M is an 8-bit identity comparator. This magnitude comparator features active low outputs indicating when the two 8-bit binary or BCD words are identical (A=B). Designed for operation with a supply voltage range of 4.5V to 5.5V, it exhibits a maximum propagation delay of 34ns at 4.5V with a 50pF load. The device is housed in a 20-SOIC (0.295", 7.50mm Width) package suitable for surface mounting. Typical quiescent current is 8 µA, with output current capabilities of 4mA for both high and low states. This component finds application in digital logic systems, control circuitry, and data processing across various industrial sectors.
