The CY74FCT2245ATPC is an 8-bit non-inverting transceiver from the 74FCT series, built for bidirectional data flow on 5V buses. It carries one element of eight bits each, with 3-state outputs that let you isolate the bus when the chip is deselected — standard fare for memory-mapped I/O, peripheral backplanes, and parallel data paths in industrial controllers or telecom line cards.
5V supply, industrial temperature — who this part serves
The supply range is 4.75V to 5.25V, squarely in the classic 5V logic domain — no 3.3V or 1.8V core here.
Through-hole rework — the DIP advantage
The 20-DIP package is through-hole, which means it survives rework cycles that would kill a fine-pitch SOIC. If you need to swap it on a prototype board or replace it in a field-return unit, a standard DIP socket or a desoldering station handles it cleanly. No hot-air profile to tune, no hidden pads under the body. The 0.300" row spacing fits breadboards and perfboard layouts, so it is also a common choice for one-off test fixtures or low-volume control boards where surface-mount assembly is not available.
Lifecycle — active, no LTB pressure
For a through-hole 5V logic part in 2025, that is a practical advantage — many peers have already moved to surface-mount or been discontinued.
