PI74AVC+16244 is a non-inverting 16-bit buffer/driver designed for low-voltage 1.65V to 3.6V VCC operation. The buffer/driver is designed specifically to improve both the performance and density of 3-state memory address drivers, clock drivers, and bus-oriented receivers and transmitters. The device can be used as four 4-bit buffers, two 8-bit buffers, or one 16-bit buffer. It provides non-inverting outputs and symmetri- cal active-low output-enable (OE) inputs. To ensure the high-impedance state during power up or power down, OE should be tied to V CC through a pullup resistor in which the minimum value is determined by the current-sinking capability of the driver. 1234567890123456789012345678901212345678901234567890123456789012123456789012345678901234567890121234567890123456789012345678901 2123456789012 1 2345678901234567890123456789012123456789012345678901234567890121234567890123456789012345678901212345678901234567890123456789012 12345678901 2 1234567890123456789012345678901212345678901234567890123456789012123456789012345678901234567890121234567890123456789012345678901 2123456789012 2.5V 16-Bit Buffer Driver with 3-State Outputs Logic Block Diagram Product Features
