54ACT16825
description
The ’ACT16825 18-bit buffers/drivers are designed specifically to improve both the performance and density of 3-state memory address drivers, clock drivers, and bus-oriented receivers and transmitters.
The ’ACT16825 can be used as two 9-bit buffers or one 18-bit buffer. They provide true data from A to Y.
The 3-state control gate is a 2-input NOR gate; therefore, if either output-enable (OE1 or OE2) input is high, all nine affected outputs are in the high-impedance state.
