It provides eight non-inverting channels with 3-state outputs. ## Supply rail and temperature — the hard limits The supply range is 4.75 V to 5.25 V. The operating temperature is 0°C to 70°C. ## Output drive and bus loading The SN74LS245DWR sources 15 mA and sinks 24 mA per channel. The 3-state outputs let you share a bus with other transceivers. ## Package and assembly The part comes in a 20-pin SOIC wide-body package (7.50 mm body width), surface-mount only. ## Lifecycle and sourcing reality The SN74LS245DWR is listed as Active on TI's product status. TI continues to manufacture these parts for legacy support and new designs that do not need the speed or voltage range of newer families.
