description

The ’ABT16240A devices are 16-bit buffers and

line drivers designed specifically to improve both

the performance and density of 3-state memory

address drivers, clock drivers, and bus-oriented

receivers and transmitters.

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

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 VCC through a pullup

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

The SN54ABT16240A is characterized for operation over the full military temperature range of –55°C to 125°C.

The SN74ABT16240A is characterized for operation from –40°C to 85°C.
