MM74HC688WMX Description

Short technical summary and product information.

The MM74HC688WMX from On Semiconductor is an 8-bit magnitude comparator that functions as an equality detector. It utilizes advanced silicon-gate CMOS technology to compare two 8-bit words bit by bit, indicating equality when its output is LOW. This device is suitable for memory block decoding and other applications requiring word comparison.

 

Key electrical specifications include a wide operating supply voltage range of 2V to 6V and a typical propagation delay of 30ns at 6V and 50pF. The comparator operates across a temperature range of -40°C to 85°C.

 

Packaged in a 20-SOIC (0.295", 7.50mm Width) surface mount package, the MM74HC688WMX is designed for ease of integration into various electronic assemblies. Its output can drive up to 10 low-power Schottky equivalent loads. The device is functionally and pin-compatible with the 74LS688.
