Propagation delay < 1.5ns max with 15pf load . Low input capacitance: 4pf typical . Available in 48pin TSSOP package DESCRIPTION: Potato Semiconductor’s PO74G16244A 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 Octal bus buffer gate is designed for 1.65-V to 3.6-V VCC operation. The PO74G16244A features independent line driver swith 3-state outputs. Each output is disabled when the associated output- enable(OE) input is high. 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.
