8-bit bus transceiver for 5V backplane and peripheral interfaces
The CY74FCT2245ATSOC is an 8-bit non-inverting transceiver from the 74FCT logic family, with 3-state outputs that allow bidirectional data flow on a single bus.
Output drive and supply — sizing for the bus load
With 15mA high-level and 12mA low-level output current, this transceiver can drive moderate capacitive loads on short PCB traces or a few TTL inputs per line. The 4.75V to 5.25V supply range covers the full 5V ±5% tolerance, so it works with legacy 5V rails and regulated 5V supplies in mixed-voltage systems. The single-element, 8-bit configuration matches byte-wide data paths without needing multiple devices.
Package and footprint — 20-SOIC wide-body
Housed in a 20-SOIC wide-body package (0.295" body width, 7.50mm), this surface-mount transceiver uses the standard JEDEC SOIC-20W footprint. The wide-body variant offers better thermal dissipation and easier manual inspection than the narrow SOIC.
The industrial range ensures reliable operation in unconditioned enclosures and seasonal temperature swings.
Lifecycle and compliance — active production, ROHS3
The ROHS3 compliance covers the latest EU exemption updates, which simplifies compliance for export-bound equipment.
