Bus-hold data inputs eliminate the need for external pullup resistors

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) VCC operation, but with the capability to provide a TTL interface to a 5V system environment.

The 54LVTH244A is organized 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.


About RAD-PAK® Technology

Maxwell Technologies' patented RAD-PAK® packaging technology 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, RAD-PAK provides greater than 100 krad (Si) radiation dose tolerance. This product is available with screening up to Class S.
