NXP USA Inc. presents the 74HCT688DB-112, an 8-bit identity comparator from the 74HCT series. This device features active low outputs confirming equality (A=B) between two 8-bit data words. Optimized for high-speed operation, it offers a maximum propagation delay of 34ns at 4.5V with a 50pF load. The component operates within a voltage supply range of 4.5V to 5.5V, drawing a quiescent current of only 8 µA. With a current drive capability of 4mA for both high and low outputs, it is suitable for applications requiring precise digital comparison. The 74HCT688DB-112 is supplied in a 20-SSOP package, designed for surface mounting. This comparator finds application in digital signal processing, data acquisition systems, and control logic within various industrial and consumer electronics sectors.
