SN74ABT2244A Datasheet | Texas Instruments

description 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 SN54ABT2240, SN74ABT2240A, and ’ABT2241, these devices provide the choice of selected binations of inverting and noninverting outputs, symmetrical active-low output-enable (OE) inputs, and plementary OE and OE inputs. These devices feature high fan-out and improved fan-in. 2Y1 GND 2A1 1Y4 2A2 SN54ABT2244A . . . J OR W PACKAGE SN74ABT2244A . . .

When VCC is between 0 and 2.1 V, the device is in the high-impedance state during power up or power down. However, to ensure the high-impedance state above 2.1 V, 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 SN54ABT2244A is characterized for operation over the full military temperature range of - 55°C to 125°C. The SN74ABT2244A is characterized for operation from - 40°C to 85°C.
