DESCRIPTION:
Potato Semiconductor’s PO74G2305A is
designed for world top performance using
submicron CMOS technology to achieve
750MHz TTL output frequency with less than
80ps output pin to pin skew.
PO74G2305A is a 3.3V CMOS 1 input to 5
outputs Buffered driver to achieve 750MHz
output frequency. Typical applications are
clock and signal distribution.
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.
