DESCRIPTION/ORDERING INFORMATION

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-W 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.
