NXP USA Inc. 74HCT series 74HCT688DB-118 is an 8-bit identity comparator. This high-speed CMOS device features active-low outputs indicating when all corresponding input bits are equal (A=B). Designed for operation from 4.5V to 5.5V, it exhibits a maximum propagation delay of 34ns at 4.5V with a 50pF load. The device supports 4mA output current for both high and low states and has a quiescent current of 8 µA. Packaged in a 20-SSOP (0.209", 5.30mm Width) surface-mount configuration, it is supplied on tape and reel. The operating temperature range is -40°C to 125°C. This comparator finds application in digital systems requiring precise bit-wise comparison, including data routing, error detection, and system control within industrial automation and telecommunications.
