description
/ordering information
The ’BCT2244 devices 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 ’BCT2240 devices and SN74BCT2241, 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.
To ensure the high-impedance state during power up or power down, 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 outputs, which are designed to source or sink up to 12 m A, include 33-Ω series resistors to reduce overshoot and undershoot.
