DESCRIPTION/ORDERING INFORMATION

The 'LVTH162240 devices are 16-bit buffers/drivers designed specifically for low-voltage (3.3-V) VCC operation

and to improve both the performance and density of 3-state memory address drivers, clock drivers, and

bus-oriented receivers and transmitters. They have the capability to provide a TTL interface to a 5-V system

environment.

These devices can be used as four 4-bit buffers, two 8-bit buffers, or one 16-bit buffer and provide inverting

outputs and symmetrical active-low output-enable (OE) inputs.

The outputs, which are designed to source or sink up to 12 mA, include equivalent 22-W series resistors to

reduce overshoot and undershoot.

When VCC is between 0 and 1.5 V, the devices are in the high-impedance state during power up or power down.

However, to ensure the high-impedance state above 1.5 V, 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.
