Potato Semiconductor’s PO74G125A 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 quadruple bus buffer gate is designed for 1.65-V
to 3.6-V VCC operation.
The PO74G125A features independent line drivers with
3-state outputs. Each output is disabled when the
associated output-enable (OE) input is high. To ensure
the high-impedance state during power up or power
down, OE should be tied to VCC through a pullup
resistor; the minimum value of the resistor is
determined by the current-sinking capability of
the driver.
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.
