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 ’BCT241 and ’BCT244 devices, these devices provide the choice of selected combinations of inverting and noninverting outputs, symmetrical (OE)\ (active-low output-enable) inputs, and complementary 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 VCCthrough a pullup resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.

The SN54BCT541 and SN74BCT541A octal buffers and line drivers are ideal for driving bus lines or buffering memory-address registers. The devices feature inputs and outputs on opposite sides of the package to facilitate printed-circuit-board layout. The 3-state control gate is a 2-input AND gate with active-low inputs so that, if either output-enable (OE1\ or OE2\) input is high, all eight outputs are in the high-impedance state.

The ´BCT620A bus transceiver is designed for asynchronous communication between data buses. The control function implementation allows for maximum flexibility in timing. The ´BCT620A provides inverted data at its outputs. These devices allow data transmission from the A bus to the B bus or from the B bus to the A bus depending upon the logic levels at the output-enable (OEAB and) inputs. The output-enable inputs can be used to disable the device so that the buses are effectively isolated. The dual-enable configuration gives the transceivers the capability of storing data by simultaneously enabling OEAB and. When both OEAB andare enabled and all other data sources to the two sets of bus lines are at high impedance, both sets of bus lines (16 in all) will remain at their last states.

The 'BCT543 octal transceiver contains two sets of D-type latches for temporary storage of data flowing in either direction. Separate latch-enable (LEAB\ or LEBA\) and output-enable (OEAB\ or OEBA\) inputs are provided for each register to permit independent control in either direction of data flow. The A-to-B enable (CEAB\) input must be low in order to enter data from A or to output data from B. If CEAB\ is low and LEAB\ is low, the A-to-B latches are transparent; a subsequent low-to-high transition of LEAB\ puts the A latches in the storage mode. With CEAB\ and OEAB\ both low, the 3-state B outputs are active and reflect the data present at the output of the A latches. Data flow from B to A is similar but requires using the CEBA\, LEBA\, and OEBA\ inputs. The SN54BCT543 is characterized for operation over the full military temperature range of \x9655°C to 125°C.
