Product details

What this 8-bit bus transceiver does in the assembly

It packs eight bits per element in a single-element package, with 3-state outputs that let you isolate the bus when the chip is disabled — handy for shared lines in a backplane or memory interface.

Temperature range and environment — commercial only, no cold soak

It belongs in an indoor, climate-controlled PCB — office equipment, appliances, or a test rack. Not for a motor drive cabinet or an outdoor telecom enclosure where the temperature swings below freezing.

Package and mounting — surface-mount SOIC, reworkable

No thermal pad, no hidden leads — you can swap it with a hot-air station if the board comes back for repair. The supplier device package is 20-SOIC, so the footprint matches any standard SOIC-20 land pattern.

Frequently asked questions

What is the function of SN74LS245DW?

It is an 8-bit non-inverting bus transceiver with 3-state outputs, used to buffer and control bidirectional data flow between two buses in a 5 V digital system.

What is the closest functional equivalent or replacement for SN74LS245DW?

The SN74LS645-1N is a through-hole (DIP) version of the same 8-bit non-inverting transceiver, but its package is not surface-mount — it won't fit the same PCB footprint. For a drop-in SOIC replacement, stick with the SN74LS245DW.
