These bus transceivers are designed for asynchronous three-way communicationbetween four-line data buses. They give the designer a choice of selectinginverting, noninverting, or a combination of inverting and noninverting datapaths with either 3-state or open-collector outputs.
The S0 and S1 inputs select the bus from which data are to be transferred.The G\ inputs enable the bus or buses to which data are to be transferred.The port for any bus selected for input and any other bus not enabled foroutput will be at high impedance including those of the open-collector devices.
The SN54LS440 through SN54LS442 and SN54LS444 are characterized for operationover the full military temperature range of -55°C to 125°C. The SN74LS440through SN74LS442 and SN74LS444 are characterized for operation from 0°Cto 70°C.
