Texas Instruments 20-SOIC CD74HCT688ME4

The CD74HCT688ME4 is a high-speed CMOS 8-bit magnitude comparator manufactured by Texas Instruments. This integrated circuit compares the magnitude of two 8-bit digital words and provides low-active outputs indicating if the inputs are equal (A=B). It features enable inputs, allowing control over the comparison operation. The device operates with a voltage supply range from 4.5 V to 5.5 V and has typical propagation delays of around 34ns at 4.5V with a load capacitance of 50pF. With a power consumption of 8μA in static conditions, it's suitable for applications requiring low power and fast comparison functionality.
