8-ch, 4.5-V to 5.5-V buffers with TTL-compatible CMOS inputs and 3-state outputs

These octal buffers and line drivers are designed specifically to improve both the performance and density of 3-state memory address drivers, clock drivers, and bus-oriented receivers and transmitters. Together with the SN54ABT240, SN74ABT240A, and 'ABT244A, these devices provide the choice of selected combinations of inverting and noninverting outputs, symmetrical active-low output-enable () inputs, and complementary OE and inputs.

To ensure the high-impedance state during power up or power down, 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. 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 SN54ABT241 is characterized for operation over the full military temperature range of -55°C to 125°C. The SN74ABT241A is characterized for operation from -40°C to 85°C.
