18-ch, 1.65-V to 3.6-V buffers with bus-hold and 3-state outputs

This 18-bit buffer and line driver is designed for 1.65-V to 3.6-V VCC operation.

This SN74ALVCH16825 improves the performance and density of 3-state memory address drivers, clock drivers, and bus-oriented receivers and transmitters.

The device can be used as two 9-bit buffers or one 18-bit buffer. It provides true data.

The 3-state control gate is a 2-input AND gate with active-low inputs so that if either output-enable (OE1\ or OE2\) input is high, all nine affected outputs are in the high-impedance state.

To ensure the high-impedance state during power up or power down, OE\ should be tied to VCC through a pullup resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.

Active bus-hold circuitry is provided to hold unused or floating inputs at a valid logic level.

The SN74ALVCH16825 is characterized for operation from &$150;40°C to 85°C.
