description
This 18-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. 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.
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.

functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not
implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
NOTES: 1. The input negative-voltage and output voltage ratings may be exceeded if the input and output current ratings are observed.
2. This value is limited to 4.6 V maximum.
