Product details

What this part is and where it fits

The SN74LS245DWR is an octal bidirectional bus transceiver from TI's 74LS family. 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. ROHS3 compliant.

Frequently asked questions

What is the difference between SN74LS245DWR and SN74LS245DW?

Both are the same die and package (20-SOIC wide). The difference is the shipping medium: DWR is Tape & Reel, DW is typically Tube. Functionally identical.
