description
The SN74ABT16240 is a 16-bit buffer and line
driver designed specifically to improve both the
performance and density of 3-state memory
address drivers, clock drivers, and bus-oriented
receivers and transmitters. The device can be
used as four 4-bit buffers, two 8-bit buffers, or one
16-bit buffer. This device provides inverting
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 V_CC through a pullup
resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.
The SN74ABT16240 is available in TI’s shrink small-outline package (DL), which provides twice the I/O pin
count and functionality of standard small-outline packages in the same printed-circuit-board area.
The SN74ABT16240 is characterized for operation from – 40°C to 85°C.
