Procurement Notes
Verify the specific revision code and marking details upon receipt, as this component is dual marked. Confirm that the TSSOP-20 package dimensions match your PCB footprint requirements. Ensure that the operating temperature range meets your environmental specifications. Check for any specific handling instructions related to CMOS devices. Validate the part number against the manufacturer's official documentation to ensure authenticity.
Selection Notes
Select this component when an octal bus transceiver with tri-state control is required. Consider the 9 ns propagation delay for timing-sensitive designs. The TSSOP-20 package offers a compact solution for space-constrained boards. Verify compatibility with the system's logic voltage levels. Evaluate the need for bidirectional data flow in the application design.
Part Context
This part belongs to the AC series of logic components, designed for high-speed operations. Rochester Electronics provides these parts as surplus or obsolete inventory solutions. The 54AC245 variant is widely used in digital systems requiring reliable data transmission. The BSA suffix indicates specific packaging and marking characteristics.
Replacement Considerations
Compatible substitutes include other octal bus transceivers from the same family, such as the 54ACT245 or SN74ACT245 variants, provided pinouts and electrical characteristics align. Verify package compatibility before substitution.
