Technical Details & Description

8-bit bus transceiver for 5V backplanes

The SN74ACT245NS: The single-element, 8-bit architecture makes it a drop-in replacement for the ubiquitous 74ACT245 in a wide-body SOIC-20 footprint.

Industrial temperature range and wide-body SOIC

The package body width is 0.209 inch (5.30 mm), the standard wide SOIC-20 footprint, compatible with many existing PCB layouts and socket options. Surface-mount assembly keeps board space tight, though the wide body helps with manual inspection and rework compared to finer-pitch packages.

Active lifecycle, no obsolescence pressure

The 74ACT family is mature but still widely supported; for a higher-drive alternative, the SN74ABT2245DW offers 32mA output current in the same 20-SOIC footprint, though it draws more supply current. Both are active and available through independent distribution.

Frequently asked questions

What is the difference between SN74ACT245 and SN74ACT245NS?

The SN74ACT245NS is the surface-mount version in a 20-SOIC wide-body package, while the SN74ACT245 (without the 'NS' suffix) typically refers to a through-hole DIP package. Functionally they are identical — same 8-bit non-inverting transceiver with 3-state outputs, same 24mA drive, same 4.5V–5.5V supply range.

What is the equivalent or replacement for SN74ACT245NS?

A close functional equivalent is the SN74ABT2245DW, which offers 32mA output drive in the same 20-SOIC footprint. The main trade-off is higher dynamic power consumption with the ABT family.
