Maxwell Technologies’ 54LVTH244A octal buffers/drivers

micro-circuit is housed in a Rad-Pak® package. The

54LVTH244A is designed specifically for low voltage (3.3V)

V

face to a 5V system environment. The 54LVTH244A is orga-

nized as two 4-bit drivers with separate output enable (OE)

inputs. When OE is low, the device passes data from the A

inputs to the Y outputs. When OE is high, the outputs are in

the high impedance state. The 54LVTH244A active bus hold

circuitry is provided to prevent floating data inputs at a valid

logic level and to eliminate the need for pullup resistors.

ogy incorporates radiation shielding in the microcircuit pack-

age. It eliminates the need for box shielding while providing

the required radiation shielding for a lifetime in orbit or a space

mission. This product is available with packaging and screen-

ing up to Class S.
