SN74ACT241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 the performance and density of 3-state memory address drivers, clock drivers, and bus-oriented receivers and transmitters.

The ’ACT241 devices are organized as two 4-bit buffers/drivers with separate complementary output-enable (1(OE)\\ and 2OE) inputs. When 1(OE)\\ is low or 2OE is high, the device passes noninverted data from the A inputs to the Y outputs. When 1(OE)\\ is high or 2OE is low, 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 VCC through a pullup resistor and OE should be tied to GND through a pulldown resistor; the minimum value of the resistor is determined by the current-sinking or the current-sourcing capability of the driver.
