SN74ALVCHS162830中文资料具有总线保持和三态输出的 18 通道、2.3V 至 3.6V 缓冲器数据手册TI规格书

描述 Description

This 1-bit to 2-bit address driver is designed for 2.3-V to 3.6-V VCC operation.

Diodes to VCC have been added on the inputs to clamp overshoot.

Active bus-hold circuitry holds unused or undriven inputs at a valid logic state. Use of pullup or pulldown resistors with the bus-hold circuitry is not recommended.

The outputs, which are designed to sink up to 12 mA, include equivalent 26- series resistors to reduce overshoot and undershoot.

To ensure the high-impedance state during power up or power down, the output-enable (OE)\\ input 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.
