description
The ’ABT16241A 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
true outputs and complementary output-enable (OE and OE) inputs.
To ensure the high-impedance state during power up or power down, OE should be tied to V through a pullup
CC
resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver. OE
should be tied to GND through a pulldown resistor; the minimum value of the resistor is determined by the
current-sourcing capability of the driver.
The SN54ABT16241A is characterized for operation over the full military temperature range of –55°C to 125°C.
The SN74ABT16241A is characterized for operation from –40°C to 85°C.
