Texas Instruments SN74HC688DW is an 8-bit identity comparator from the 74HC series. This device features active-low outputs indicating when two 8-bit binary or BCD words are identical. It operates over a voltage range of 2V to 6V with a typical quiescent current of 8 µA. The maximum propagation delay is 36ns at 6V with a 50pF load. With a current drive of 5.2mA for both high and low outputs, it is suitable for applications in industrial automation, consumer electronics, and telecommunications. The SN74HC688DW is available in a 20-SOIC (0.295", 7.50mm Width) surface mount package.
