Potato Semiconductor’s PO74G38072A is designed for world top performance using submicron CMOS technology to achieve 1GHz TTL output frequency with less than 20ps output pin to pin skew.

PO74G38072A is a 3.3V CMOS 1 input to 2 outputs Buffered driver to achieve 1GHz 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.
