FEATURES:. Patented technology. Operating frequency up to.25ghz with 2pf load. Operating frequency up to 700MHz with 5pf load. Operating frequency up to 300MHz with 5pf load. Operating frequency up to 00MHz with 50pf load. Operates from.65v to 3.6V. Propagation delay <.5ns max with 5pf load. Low input capacitance: 4pf typical. Available in pin TSSOP package DESCRIPTION: Potato Semiconductor s is designed for world top performance using submicron CMOS technology to achieve.25ghz TTL /CMOS output frequency with less than.5ns propagation delay. This Octal bus buffer gate is designed for.65-v to 3.6-V operation. The features independent line driver swith 3-state outputs. Each output is disabled when the associated output- enable(oe) input is high. s 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.
