DESCRIPTION:

•

3.3V low voltage advanced BiCMOS technology (LVT) 16-

Maxwell Technologies’ 54LVTH16373 16-bit transparent D-

type latches with 3-state output features a greater than 100

krad (Si) total dose tolerance, dependent upon space mission.

The 54LVTH16373 is designed for low voltage (3.3V) V_CC

operation, but with the capability to provide a TTL interface to

a 5V system environment. It is suitable for implementing buffer

registers, I/O ports, bidirectional bus drivers, and working reg-

isters. The 54LVTH16373 can be used as two 8-bit latches or

one 16-bit latch. When the latch-enable (LE) input is low, the

Q output are latched at the levels set up at the data (D) inputs.

When LE is high, the Q outputs follow the D inputs. A buffered

output-enable (OE) input can be used to place the eight out-

puts in either a normal logic state or a high impedance state.

In the high impedance state, the outputs neither load nor drive

the bus lines significantly. The high impedance state and the

increased drive provide the capability to drive bus lines with-

out the need for interface or pullup components. OE does not

affect internal operations of the latch. Old data can be retained

or new data can be entered while the outputs are in the high

impedance state.

bit transparent D-type latches with 3-state outputs

Total dose hardness:

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

Single event effect:

- SEL_TH: No LU > 119 MeV/mg/cm²

Package: 48 pin RAD-PAK® flat package

Operating temperature range:

- 55 to 125°C

•

Distributed V_CCand GND pin configuration minimizes high-

speed switching noise

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

•

Latch-up performance exceeds 500mA per JEDEC stan-

dard

•

Supports live insertion

Bus-hold data inputs eliminate the need for external pullup

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.
