description
ABT162244 16-bit buffers line drivers designed specifically improve both performance density 3-state memory address drivers, clock drivers, bus-oriented receivers transmitters. These devices used four 4-bit buffers, 8-bit buffers, 16-bit buffer. These devices provide noninverting outputs symmetrical active-low output-enable (OE) inputs.
outputs, which designed source sink include series resistors reduce overshoot undershoot. ensure high-impedance state during power power down, should tied through pullup resistor; minimum value resistor determined current-sinking capability driver. SN74ABT162244 available TI's shrink small-outline package (DL), which provides twice count functionality standard small-outline packages same printed-circuit-board area. SN54ABT162244 characterized operation over full military temperature range 55°C 125°C. SN74ABT162244 characterized operation from 40°C 85°C.
