16-Bit Bus Transceivers with

3-State Outputs

Logic Diagram

FEATURES:

DESCRIPTION:

• A-Port outputs have equivalent 22-Ω series resistors, so

no external resistors are required

Maxwell Technologies’ 54LVTH162245 devices are 16-bit

(dual-octal) non-inverting 3-state transceivers designed for

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

low-voltage (3.3V) V operation, but with the capability to

voltages with 3.3V V )

• Support unregulated battery operation down to 2.7V

provide a TTL interface to a 5V system environment. These

devices can be used as two 8-bit transceivers or one 16-bit

transceiver. The devices allow data transmission from the A

bus to the B bus or form the B bus to the A bus, depending on

the logic level at the direction-control (DIR) input. The output

enable (OE) input can be used to disable the device so that

the buses are effectively isolated. The A-port outputs, which

are designed to source or sink up to 12 mA, include equivalent

22-Ω series resistors to reduce overshoot and undershoot.

• TypicalV_OLP(output ground bounce) < 0.8V at V_CC=3.3V,

T =25^°C

• I_OFFand power-up 3-state support hot insertion

• Bus hold on data inputs eliminates the need for external

pullup/pulldown resistors

• Distributed V_CCand GND pin configuration minimizes high-

speed switching noise

• Flow-through architecture optimizes PCB layout

• Total dose hardness:

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

• Package: 48 pin R^AD-PAK® flat pack

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.
