Maxwell Technologies’ 54BCT245 octal bus transceiver fea-

tures a greater than 100 krad (Si) total dose tolerance. The

54BCT245 is designed specifically for asynchronous commu-

nication between data buses. The 54BCT245 transmits data

from the A bus to the B bus or from the B bus to the A bus

depending upon the level at the direction-control (DIR) input.

The output-enable (OE) input can be used to disable the

device so the buses are effectively isolated.

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 space

krad (Si) radiation dose tolerance. This product is available

with screening up to Class S.
