FEATURES:

DESCRIPTION:

•

RAD-PAK® radiation-hardened against natural space radia-

tion

Maxwell Technologies’ 54LVTH162244 devices are 16-bit buff-

ers and line drivers designed for low-voltage (3.3V) V_CCoper-

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.

Total dose hardness:

- > 100 krad (Si), depending upon space mission

Output ports have equivalent 22-Ω series resistors, so no

external resistors are required

Support mixed-mode signal operation (5V input and output

voltages with 3.3V V_CC

)

•

Support unregulated battery operation down to 2.7V

Typical V_OLP(Output ground bounce) < 0.8V at V_CC= 3.3V,

T_A= 25^°C

The outputs, which are designed to source or sink up to 12

mA, include equivalent 22-Ω series resistors to reduce over-

shoot and undershoot. Active bus-hold circuitry is provided to

hold unused or floating data inputs at a valid logic level.

•

I_OFFand power-up 3-state support hot insertion

Bus hold on data inputs eliminates the need for external

pull-up/pull-down resistors

Maxwell Technologies' patented R^AD-PAK® packaging technol-

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

mission. In a GEO orbit, R^AD-PAK provides greater than 100

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

with screening up to Class S.

•

Distributed V_CCand GND pin configuration minimizes high-

speed switching noise

•

Flow-through architecture optimizes PCB layout

Package: 48 pin R^AD-PAK flat pack
