description (continued)
The devices can be used as four 4-bit buffers, two 8-bit buffers, or one 16-bit buffer. The devices provide
inverting outputs and symmetrical active-low output-enable (OE) inputs.
When V
is between 0 and 1.5 V, the device is in the high-impedance state during power up or power down.
CC
However, to ensure the high-impedance state above 1.5 V, OE should be tied to V
the minimum value of the resistor is determined by the current-sinking capability of the driver.
through a pullup resistor;
CC
Active bus-hold circuitry is provided to hold unused or floating data inputs at a valid logic level.
The SN54ALVTH16240 is characterized for operation over the full military temperature range of –55°C to
125°C. The SN74ALVTH16240 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 and output negative-voltage ratings may be exceeded if the input and output clamp-current ratings are observed.
2. The package thermal impedance is calculated in accordance with JESD 51.
