description
This 18-bit universal bus driver is designed for
1.65-V to 3.6-V V 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. When LE is low, 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 through a pullup
CC
resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.
The output port includes equivalent 26-Ω series resistors to reduce overshoot and undershoot.
The SN74ALVC162835 is characterized for operation from –40°C to 85°C.

Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings only, and
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.
3. The package thermal impedance is calculated in accordance with JESD 51.
