SN74ALVCH16825中文资料具有总线保持和三态输出的 18 通道、1.65V 至 3.6V 缓冲器数据手册TI规格书

描述 Description

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.
