DESCRIPTION:

•

3.3V ABT octal bus transceiver with 3-state outputs

R^AD-PAK® radiation hardened against natural space radia-

tion

Maxwell Technologies’ 54LVTH245A 8-bit octal transceiver

micro-circuit features a greater than 100 krad (Si) total dose

tolerance, depending upon space mission. The 54LVTH245A

is designed specifically for low voltage (3.3V) V_CCoperation,

but with the capability to provide a TTL interface to a 5V sys-

tem environment. It is designed for asynchronous communica-

tion between data buses. The device transmits data from the

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

upon the logic 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. The 54LVTH245A active

bus-hold circuitry is provided to prevent floating data inputs at

a valid logic level and to eliminate the need for external pullup

resistors.

•

Total dose hardness:

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

Package:

- 20 pin R^AD-PAK® flat package

- 20 pin R^AD-PAK® DIP

•

Operating temperature range:

-55 to 125^°C

Supports mixed-mode signal operation

- 5V input and output voltages with 3.3V V_CC

Supports unregulated battery operation down to 2.7V.

Typical VOLP (output ground bounce) < 0.8V at V_CC=3.3V,

T_A= 25^°C

•

Latch-up performance exceeds 500mA per JEDEC stan-

dard

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.

•

Supports live insertion

Bus-hold data inputs eliminate the need for external pullup

resistors
