[ /Title (CD74H C7266) /Subject (High Speed CMOS Logic Quad 2Input EXCLUSIVE CD74HC7266 Data sheet acquired from Harris Semiconductor SCHS219 High Speed CMOS Logic Quad 2-Input EXCLUSIVE NOR Gate August 1997 Features Description • Four Independent EXCLUSIVE NOR Gates The Harris CD74HC7266 contains four independent Exclusive NOR gates in one package. They provide the system designer with a means for implementation of the EXCLUSIVE NOR function. • Buffered Inputs and Outputs • Logical Comparators • Parity Generators and Checkers This device is functionally the same as the TTL226. They differ in that the HC7266 has active high and low outputs whereas the 226 has open collector outputs. • Adders/Subtracters • Fanout (Over Temperature Range) - Standard Outputs . . . . . . . . . . . . . . . 10 LSTTL Loads - Bus Driver Outputs . . . . . . . . . . . . . 15 LSTTL Loads Ordering Information • Wide Operating Temperature Range . . . -55oC to 125oC TEMP.
