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.

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.
