PO74G2305A is a 3.3V CMOS 1 input to 5
outputs Buffered driver to achieve 750MHz
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.
