Potato Semiconductor’s PO74G2308A is
designed for world top performance using
submicron CMOS technology to achieve
700MHz output frequency with less than 100ps
output pin to pin skew.
Pin Configuration
PO74G2308A is a 1.65V to 3.6V CMOS
1 input to 8 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.

For conditions shown as Max. or Min., use appropriate value specified under Electrical Characteristics for the applicable device type.
Typical values are at Vcc = 3.3V, 25 °C ambient.
This parameter is guaranteed but not tested.
Not more than one output should be shorted at one time. Duration of the test should not exceed one second.
