PO74G125A www.potatosemi.com QUADRUPLE BUS BUFFER GATES WITH 3-STATE OUTPUTS 74 Series Noise Cancellation GHz Logic FEATURES: DESCRIPTION: . Patented technology . Operating frequency up to 1.125GHz with 2pf load . Operating frequency up to 550MHz with 5pf load . Operating frequency up to 300MHz 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 Potato Semiconductor’s PO74G125A 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 PO74G125A features independent line drivers with 3-state outputs. Each output is disabled when the associated output-enable (OE) input is high. To ensure the high-impedance state during power up or power down, OE should be tied to VCC through a pullup resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver. 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.
