SN74ABT2241数据手册集成电路（IC）的缓冲器驱动器接收器收发器规格书PDF

描述 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 'ABT2244A, these devices provide the choice of selected combinations of inverting and noninverting outputs, symmetrical active-low output-enable () inputs, and complementary OE andinputs. These devices feature high fan-out and improved fan-in.The outputs, which are designed to sink up to 12 mA, include equivalent 25- series resistors to reduce overshoot and undershoot.To ensure the high-impedance state during power up or power down,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. OE should be tied to GND through a pulldown resistor; the minimum value of the resistor is determined by the current-sourcing capability of the driver.The SN54ABT2241 is characterized for operation over the full military temperature range of -55°C to 125°C. The SN74ABT2241 is characterized for operation from -40°C to 85°C.
