MICROCIRCUIT DATA SHEET
1-to-8 Minimum Skew Clock Driver
General Description
The ACT2525 is a minimum skew clock driver with one input driving eight outputs
specifically designed for signal generation and clock distribution applications. The 2525
is designed to distribute a single clock to eight separate receivers with low skew across
all outputs during both the TPLH and TPHL transitions.

Note 1:
Absolute maximum ratings are those values beyond which damage to the device may
occur. The databook specifications should be met, without exception, to ensure that
the system design is reliable over its power supply, temperature, and output/input
loading variables. National does not recommend operation of CGS circuits outside
databook specifications.
