Potato Semiconductor’s PO74G244A 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 Octal bus buffer gate is designed for 1.65-V to
3.6-V VCC operation.
The PO74G244A features independent line driver swith
3-state outputs. Each output is disabled when the
associated output- enable(OE) input is high.
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.
