STMicroelectronics 74HCT series identity comparator, part number M74HCT688RM13TR, is an 8-bit magnitude comparator designed for applications requiring precise digital signal comparison. This device features active low outputs and a direct A=B comparison function. With a supply voltage range of 4.5V to 5.5V, it offers a maximum propagation delay of 32ns at 4.5V with a 50pF load. The M74HCT688RM13TR operates across a wide temperature range of -55°C to 125°C. Its 20-SOIC package (0.295", 7.50mm width) is suitable for surface mounting. Typical applications include digital logic systems, control circuitry, and data selection within industrial automation, consumer electronics, and telecommunications sectors. The component exhibits a low quiescent current of 4 µA and provides 4mA for both high and low outputs.
