8-Bit Magnitude Comparator (Equality Detector)
MM74HC688 8-Bit Magnitude Comparator (Equality Detector) September 1983 Revised February 1999 MM74HC688 8-Bit Magnitude Comparator (Equality Detector) The comparator’s output can drive 10 low power Schottky General Description equivalent loads. This comparator is functionally and pin The MM74HC688 equality detector utilizes advanced sili- compatible to the 74LS688. All inputs are protected from con-gate CMOS technology to compare bit for bit two 8-bit damage due to static discharge by diodes to V and CC words and indicates whether or not they are equal. The ground. P=Q output indicates equality when it is LOW. A single active low enable is provided to facilitate cascading of sev- Features eral packages and enable comparison of words greater than 8 bits. � Typical propagation delay: 20 ns This device is useful in memory block decoding applica- � Wide power supply range: 2–6V tions, where memory block enable signals must be gener- � Low quiescent current: 80 μA (74 Series) ated from computer address information. � Large output current: 4 mA (74 Series) � Same as HC521 Ordering Code: Order Number Package Number Package Description MM74HC688WM M20B 20-Lead Small Outline Integrated Circuit (SOIC), JEDEC MS-013, 0.300” Wide MM74HC688SJ M20D 20-Lead Small Outline Package (SOP), EIAJ TYPE II, 5.3mm Wide MM74HC688MTC MTC20 20-Lead Thin Shrink Small Outline Package (TSSOP), JEDEC MO-153, 4.4mm Wide MM74HC688N N20A 20-Lead Plastic Dual-In-Line Package (PDIP), JEDEC MS-001, 0.300” Wide Devices also available in Tape and Reel.
