3.3V ABT 8-Bit Octal

Buffers/Drivers

Logic Diagram

FEATURES:

DESCRIPTION:

•

3.3V ABT octal buffers/drivers with 3-state outputs

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

tion

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)

•

Package:

V_CCoperation, but with the capability to provide a TTL inter-

- 20 Pin R^AD-PAK® flat package

Operating temperature range:

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.

-55 to 125^°C

Supports mixed-mode signal operation

-5V Input and Output Voltages with 3.3V V_CC

Supports mixed-mode signal operation

- 5V input and output voltages with 3.3V V_CC

Supports unregulated battery operation down to 2.7V

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

T_A=25^°C

•

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 a space

mission. This product is available with packaging and screen-

ing up to Class S.

•

Supports live insertion

Bus-hold data inputs eliminate the need for external pullup

resistors
