DESCRIPTION:
. Patented technology
. Operating frequency up to 800MHz with 2pf load
. Operating frequency up to 700MHz with 5pf load
. Operating frequency up to 400MHz with 15pf load
. VCC Operates from 1.65V to 3.6V
. Propagation delay < 1.7ns max with 15pf load
. Low input capacitance: 4pf typical
. Available in 14pin 150mil wide SOIC package
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.

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.
