Texas Instruments 74HCT series identity comparator, part number CD74HCT688EG4, is an 8-bit magnitude comparator designed for digital logic applications. This component features active low outputs, indicating equality (A=B) between two 8-bit data words. Operating over a supply voltage range of 4.5V to 5.5V, it offers a maximum propagation delay of 34ns at 4.5V with a 50pF load. Quiescent current is a low 8 µA, with output drive capabilities of 4mA high and low. The device is supplied in a 20-PDIP (0.300", 7.62mm) through-hole package, suitable for robust board mounting. Its functionality makes it valuable in data synchronization, address decoding, and control systems across various industrial and consumer electronics sectors.
