54LVTH244A  
3.3V ABT 8-Bit Octal  
Buffers/Drivers  
Logic Diagram  
FEATURES:  
DESCRIPTION:  
3.3V ABT octal buffers/drivers with 3-state outputs  
RAD-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:  
VCC operation, but with the capability to provide a TTL inter-  
- 20 Pin RAD-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 VCC  
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  
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 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
