Potato Semiconductor’s PO74G126A 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 PO74G126A featuresindependent
linedriverswith3-stateoutputs. Eachoutput isdisabled-
whenthe associatedoutput-enable(OE)input islow.
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.

Notes:
1. For conditions shown as Max. or Min., use appropriate value specified under Electrical Characteristics for the applicable device type.
2. Typical values are at Vcc = 3.3V, 25 °C ambient.
3. This parameter is guaranteed but not tested.
4. Not more than one output should be shorted at one time. Duration of the test should not exceed one second.
5. VoH = Vcc – 0.6V at rated current
