DESCRIPTION/ORDERING INFORMATION
This 16-bit universal bus driver is designed for 1.65-V
to 3.6-V V_CC 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-Ω resistors to reduce overshoot and
undershoot.
To ensure the high-impedance state during power up or power down, OE should be tied to V_CC through a pullup
resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.
