DESCRIPTION:

Potato Semiconductor’s PO74G16241A 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 V

CC

 operation.

The

PO74G16241A

features independent line driver 

swith 3-state outputs. Each output is disabled when the 

associated output- enable input is high or low.

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.
