Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the manufacturer origin as Fairchild Semiconductor or its successor ON Semiconductor, noting the acquisition occurred in September 2016. Confirm the package type is 56-BSSOP and the operating voltage aligns with ACT logic standards. Ensure the datasheet matches the specific suffix SSC for pinout and mechanical dimensions. Cross-reference ordering codes with authorized distributors to avoid counterfeit components.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring 16-bit bidirectional data paths with internal latching. The ACTQ series offers faster switching speeds compared to standard TTL equivalents. Consider the 56-pin SSOP package constraints for PCB layout. Verify that the supply voltage range supports the target application's logic levels. Ensure compatibility with other ACT family devices for seamless integration.

Buffers, Drivers, Receivers, Transceivers Part Context

The 74ACTQ16543 belongs to the ACTQ family of high-speed CMOS logic devices. Fairchild Semiconductor was acquired by ON Semiconductor in 2016, making ON Semi the current provider of these parts. The Q variant typically denotes enhanced performance characteristics. This specific model is designed for complex digital systems needing robust data handling and isolation capabilities across wide buses.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Check for direct substitutes from ON Semiconductor such as the 74ACTQ16543MTD. Verify pin compatibility and electrical specifications before substitution. Other families like 74FCT may offer similar functionality but require voltage level verification.
