Potato Semiconductor’s

PO74G2309A

is

designed for world top performance using
submicron

CMOS

technology

to

achieve

700MHz output frequency with less than 100ps

output pin to pin skew.

PO74G2309A is a 1.2V to 3.6V CMOS
1 input to 9 Output Buffered Driver to
achieve 700MHz output frequency.
Typical applications are clock and signal distribution.

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.
