DESCRIPTION:

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) VCC operation, but with the capability to provide a TTL interface to a 5V system environment.

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.

FEATURES:

• 3.3V ABT octal buffers/drivers with 3-state outputs

• RAD-PAK® radiation-hardened against natural space radiation

• Package: - 20 Pin RAD-PAK® flat package

• Operating temperature range: -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

• Supports live insertion

• Bus-hold data inputs eliminate the need for external pullup resistors
