NXP USA Inc. 74HCT series 74HCT688D-653 is an 8-bit identity comparator designed for applications requiring precise digital signal comparison. This device features an active low output indicating when all corresponding bits of two 8-bit inputs are equal (A=B). Operating within a 4.5V to 5.5V supply range, it offers a maximum propagation delay of 34ns at 4.5V with a 50pF load capacitance. The 74HCT688D-653 exhibits a quiescent current of 8 µA and provides a consistent output drive of 4mA for both high and low states. This component is housed in a 20-SOIC (0.295", 7.50mm Width) surface-mount package, supplied on tape and reel. Its robust design makes it suitable for use in industrial automation, telecommunications, and consumer electronics sectors.
