DESCRIPTION/ORDERING INFORMATION
This 18-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
high. The A data is latched if the clock (CLK) input is
held at a high or low logic level. If LE is low, 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.
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.
