| QUADRUPLE BUS BUFFER GATE WITH 3-STATE OUTPUTS PO74G126A 02/07/07 74 Series GHz Logic FEATURES: . Patented technology . Operating frequency up to 1.125GHz with 2pf load . Operating frequency up to 700MHz with 5pf load . Operating frequency up to 400MHz with 15pf load . VCC Operates from 1.65V to 3.6V . Propagation delay < 1.5ns max with 15pf load . Low input capacitance: 4pf typical . Available in 14pin 150mil wide SOIC package DESCRIPTION: Potato Semiconductor's PO74G126A is designed for world top performance using submicron CMOS technology to achieve 1.125GHz TTL /CMOS output frequency with less than 1.5ns propagation delay. This quadruple bus buffer gate is designed for 1.65-V to 3.6-V VCC operation. The PO74G126A featuresindependent linedriverswith3-stateoutputs. Eachoutput isdisabledwhenthe associatedoutput-enable(OE)input islow. Inputs can be driven from either 3.3V or 5V devices. This feature allows the use of these devices as translators in a mixed 3.3V/5V system environment.
