Propagation delay < 1.8ns max with 15pf load . Low input capacitance: 4pf typical . Available in 20pin TSSOP package . Available in 20pin Ceramic Dual Flatpack . Available in 20pin Leadless Ceramic Chip Carrier DESCRIPTION: Potato Semiconductor's PO74G373A is designed for world top performance using submicron CMOS technology to achieve higher than 1.125GHz TTL /CMOS output frequency with less than 1.8ns propagation delay. This dual Octal transparent D-type latches are designed for 1.65-V to 3.6-V VCC operation. 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.
