NXP USA Inc. 74HCT series 74HCT688D-652 is an 8-bit identity comparator. This device features active-low outputs that indicate when two 8-bit binary or BCD words are identical (A=B). Operating from a 4.5V to 5.5V supply, it offers a typical propagation delay of 34ns at 4.5V with a 50pF load. Current specifications include 4mA for output high and low, and a quiescent current of 8µA. The comparator is housed in a 20-SOIC (0.295", 7.50mm Width) surface-mount package, supplied in tubes, and operates across an industrial temperature range of -40°C to 125°C. This component finds application in digital logic, control systems, and data processing.
