The ’ABTH16244 devices are 16-bit buffers and line drivers designed specifically to improve both the performance and density of 3-state memory address drivers, clock drivers, and bus-oriented receivers and transmitters. These devices can be used as four 4-bit buffers, two 8-bit buffers, or one 16-bit buffer. These devices provide true outputs and symmetrical active-low output-enable (OE) inputs. To ensure the high-impedance state during power up or power down, OE should be tied to VCC through a pullup resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver. Active bus-hold circuitry is provided to hold unused or floating data inputs at a valid logic level. The SN54ABTH16244 is characterized for operation over the full military temperature range of –55°C to 125°C. The SN74ABTH16244 is characterized for operation from –40°C to 85°C.

Frequently Asked Questions
What is the typical output ground bounce voltage?
The typical output ground bounce is less than <1 V at V = 5 V, T = 25°C.
How should I handle the Output Enable (OE) pins during power cycling?
You must tie OE to V through a pullup resistor to ensure the high-impedance state during power up or down.
What are the temperature limitations for these drivers?
The SN54ABTH16244 is rated for –55°C to 125°C, while the SN74ABTH16244 operates from –40°C to 85°C.
Are these chips suitable for critical industrial applications?
No; they are not designed or warranted for use in life-support devices or other critical applications.
