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 ( or ) input is high all nine affected outputs are in the high-impedance state. the 74act16825 is packaged in ti s shrink small-outline package which provides twice the i/o pin count and functionality of standard small-outline packages in the same printed-circuit-board area. the 54act16825 is characterized for operation over the full military temperature range of -55c to 125c. view all in datasheet
