Active 5 V bus transceiver in wide-body SOIC
The Cypress CY74FCT245CTSOC is an 8-bit non-inverting bus transceiver from the 74FCT family, with 3-state outputs on both the A and B ports. The part sources 32 mA and sinks 64 mA per output, enough to drive heavily loaded backplane traces or multiple TTL inputs without external buffers.
The 20-SOIC wide-body package (0.295", 7.50 mm width) is the larger SOIC footprint, not the narrow 3.9 mm variant — verify the PCB land pattern before layout. The mounting is surface-mount, consistent with standard SOIC reflow profiles.
Active lifecycle and RoHS compliance
No AEC-Q automotive qualification is cited, so this is a commercial/industrial-grade part, not intended for under-hood or chassis-domain automotive applications.
