描述 Description

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.
