3.3-V ABT 16-BIT BUFFERS/DRIVERS

WITH 3-STATE OUTPUTS

SCBS716E – MARCH 2000 – REVISED DECEMBER 2006

with 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. These devices provide true outputs and symmetrical

active-low output-enable (OE) inputs.

the minimum value of the resistor is determined by the current-sinking capability of the driver.

disables the outputs, preventing damaging current backflow through the devices when they are powered down.

The power-up 3-state circuitry places the outputs in the high-impedance state during power up and power down,

which prevents driver conflict.
