54LVTH245A  
3.3V ABT Octal Bus Transceiver  
with 3-State Output  
Logic Diagram (Positive Logic)  
FEATURES:  
DESCRIPTION:  
3.3V ABT octal bus transceiver with 3-state outputs  
RAD-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) VCC operation,  
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 RAD-PAK® flat package  
- 20 pin RAD-PAK® DIP  
Operating temperature range:  
-55 to 125°C  
Supports mixed-mode signal operation  
- 5V input and output voltages with 3.3V VCC  
Supports unregulated battery operation down to 2.7V.  
Typical VOLP (output ground bounce) < 0.8V at VCC=3.3V,  
TA= 25°C  
Latch-up performance exceeds 500mA per JEDEC stan-  
dard  
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.  
Supports live insertion  
Bus-hold data inputs eliminate the need for external pullup  
resistors
