Hot-selling and scarce SN74ABT244ADW OCTAL BUFFERS/DRIVERS WITH 3-STATE OUTPUTS SOP20 spot stock

Product Descriptions

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,   SN54ABT241, and SN74ABT241A,these devices provide the choice of   selected   combinations   of   inverting   and noninverting   outputs,   symmetrical   active-low output-enable (OE) inputs, and complementary OE and OE inputs.

The SN54ABT244 and SN74ABT244A are organized as two 4-bit buffers/line drivers with separate OE inputs. When OE is low, the devices pass noninverted data from the A inputs to the Y outputs. When OE is high, the outputs are in the high-impedance state.

To ensure the high-impedance state during power up or power down, OE should be tied to V CC through a pullup resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver. 

The SN54ABT244 is characterized for operation over the full military temperature range of −55°C to 125°C.The SN74ABT244A is characterized for operation from −40°C to 85°C.
