DESCRIPTION:

Maxwell Technologies’ 54LVTH162244 devices are 16-bit buff­ers and line drivers designed for low-voltage (3.3V) V
ation, but with the capability to provide a TTL interface to a 5V
system environment. These devices can be used as four 4-bit
buffers, two 8-bit buffers, or one 16-bit buffer. These devices
provide true outputs and symmetrical active-low output-enable
(OE

) inputs.

The outputs, which are designed to source or sink up to 12
mA, include equivalent 22­shoot and undershoot. Active bus-hold circuitry is provided to
hold unused or floating data inputs at a valid logic level.

Maxwell Technologies' patented R
ogy incorporates radiation shielding in the microcircuit pack­age. It eliminates the need for box shielding while providing
the required radiation shielding for a lifetime in orbit or space
mission. In a GEO orbit, R
krad (Si) radiation dose tolerance. This product is available
with screening up to Class S.

1. Stresses beyond 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.

2. The input and output negative-voltage ratings may be exceeded if the input and output clamp-current ratings are observed.

3. This current flows only when the output is in the high state and VO > VCC.
