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  
CC  
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.  
CC  
• TypicalVOLP (output ground bounce) < 0.8V at VCC =3.3V,  
T =25°C  
A
• IOFF and power-up 3-state support hot insertion  
• Bus hold on data inputs eliminates the need for external  
pullup/pulldown resistors  
• Distributed VCC and 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 RAD-PAK® flat pack  
Maxwell Technologies' patented RAD-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, RAD-PAK provides greater than 100  
krad (Si) radiation dose tolerance. This product is available  
with screening up to Class S.
