description
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.

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.
Active bus-hold circuitry is provided to hold unused or floating data inputs at a valid logic level.
The SN74ALVCH16334 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.
