SN54BCT2240
- Operating Voltage Range of 4.5 V to 5.5 V
- State-of-the-Art BiCMOS Design Significantly Reduces ICCZ
- Output Ports Have Equivalent 33-
Series Resistors, So No External Resistors Are Required - 3-State Outputs Drive Bus Lines or Buffer Memory Address Registers
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 SN74BCT2241 and the BCT2244 devices, 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. These devices feature high fan-out and improved fan-in.
The BCT2240 devices are organized as two 4-bit line drivers with separate output-enable (OE)\ inputs. When (OE)\ is low, the device passes 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 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 mA, include 33-
series resistors to reduce overshoot
