Description

These SN74ABT16540 16-bit buffers and bus drivers provide a high-performance bus interface for wide data paths.

The 3-state control gate of SN74ABT16540 is a 2-input AND gate with active-low inputs so that if either output-enable (OE1 or OE2) input is high, all corresponding outputs are in the high-impedance state.

To ensure the high-impedance state of SN74ABT16540 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.

The SN74ABT16540 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 SN54ABT16540 is characterized for operation over the full military temperature range of 55°C to 125°C. The SN74ABT16540 is characterized for operation from 40°C to 85°C.
