It operates from a 4.75V to 5.25V supply and is specified over the industrial temperature range of –40°C to 85°C. The single-element, 8-bit-per-element architecture mirrors the classic 74FCT245 function, making it a drop-in for 5V logic translation and buffering in systems like motor drives, telecom line cards, and industrial controllers where the bus needs to be isolated or driven without inversion. ## 20-SOIC wide-body — field-swappable with standard footprint Housed in a 20-SOIC package with 7.50mm body width, the 74FCT2245ATSOG uses the same footprint as a 74FCT245 or 74ACT245 in SOIC-20W. On a field-service call, if the original part is socketed or the board has a standard SOIC-20W land pattern, this transceiver swaps in with a fine-tip iron and some flux — no hot-air station required. The wide body helps with visual alignment and reduces bridging risk during rework. ## Output drive and supply — what the 15mA/12mA rating means for your bus The 74FCT2245ATSOG sources 15mA and sinks 12mA per output, which is typical for a 5V FCT-family transceiver. That drive level is enough to switch standard TTL or CMOS loads on a short backplane trace (under 6 inches), but if you are driving a heavily loaded bus with multiple fan-outs or long cables, you will want to buffer the outputs or switch to a higher-drive part. The 4.75V minimum supply ensures the outputs hold valid logic levels even when the 5V rail droops under load — useful in power-sequenced or battery-backed systems. ## Active lifecycle — no LTB risk for production BOMs The 74FCT2245ATSOG carries an Active product status, meaning Renesas continues to manufacture it without a last-time-buy notice. For a production BOM, this part does not introduce obsolescence risk in the near term.","metaTitle":"74FCT2245ATSOG 8-Bit Transceiver, 4.75V–5.25V, 20-SOIC","metaDescription":"74FCT2245ATSOG 8-bit non-inverting transceiver with 3-state outputs, 4.75V–5.25V supply, –40°C to 85°C, 20-SOIC.
