16位通用总线驱动器,具有三态输出 16-BIT UNIVERSAL BUS DRIVER WITH 3-STATE OUTPUTS
This 16-bit universal bus driver is designed for 1.65-V to 3.6-V VCC operation.
Data flow from A to Y is controlled by the output-enable OE\\\\ input. The device operates in the transparent mode when the latch-enable LE\\\\ input is low. When LE\ is high, the A data is latched if the clock CLK input is held at a high or low logic level. If LE\ is high, the A data is stored in the latch/flip-flop on the low-to-high transition of CLK. When OE\ is high, the outputs are in the high-impedance state.
The outputs, which are designed to sink up to 12 mA, include equivalent 26- resistors to reduce overshoot and undershoot.
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.
