74ABT244Enhanced product 8-ch, 4.5-V to 5.5-V buffers with TTL-compatible CMOS inputs and 3-state outputs | Logic | 14 | Active | 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 VCCthrough 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.

74ABT282710-ch, 4.5-V to 5.5-V buffers with TTL-compatible CMOS inputs and 3-state outputs | Integrated Circuits (ICs) | 4 | Active | These 10-bit buffers or bus drivers provide a high-performance bus interface for wide data paths or buses carrying parity.
The 3-state control gate is a 2-input AND gate with active-low inputs so that if either output-enable (or) input is high, all ten outputs are in the high-impedance state. The 'ABT2827 provide true data at their outputs.
To ensure the high-impedance state during power up or power down,should be tied to VCCthrough a pullup resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.
The outputs, which are designed to source or sink up to 12 mA, include equivalent 25-series resistors to reduce overshoot and undershoot.
