Potato Semiconductor’s PO74G245A is designed for
world top performance using submicron CMOS
technology to achieve 1GHz TTL /CMOS output
frequency with less than 1.65ns propagation delay.
This Octal bus buffer gate is designed for 1.2-V to
3.6-V VCC operation.
The PO74G245A features independent 8-bit Bidirec-
tional Transceiver with 3 state outputs. Each output is
disabled when the associated output- enable(OE) input
is high.
