FEATURES:
DESCRIPTION:
. Patented technology
. Operating frequency up to 1.125GHz with 2pf load
. Operating frequency up to 700MHz with 5pf load
. Operating frequency up to 300MHz with 15pf load
Potato Semiconductor’s PO74G240A 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 inverter gate is designed for 1.65-V to
3.6-V VCC operation.
. Operating frequency up to 100MHz with 50pf load
. VCC Operates from 1.65V to 3.6V
. Propagation delay < 1.5ns max with 15pf load
. Low input capacitance: 4pf typical
. Available in 20pin TSSOP package
The PO74G240A features independent line driver swith
3-state outputs. Each output is disabled when the
associated output- enable(OE) input is high.

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.
