DESCRIPTION:
Potato Semiconductor’s PO74G27A is designed for
world top performance using submicron CMOS
technology to achieve 800MHz TTL /CMOS output
frequency with less than 1.7ns propagation delay.
This triple 3-input positive-NOR gate is designed for
1.65-V to 3.6-V VCC operation.
The PO74G27A performs the Boolean function
Y= A + B + C or Y= A · B · C in positive logic.
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.
