MICROCIRCUIT DATA SHEET Original Creation Date: 07/02/96 Last Update Date: 03/17/97 Last Major Revision Date: 02/05/97 MN54ACT2525-X REV 2A0 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.

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.
