Procurement Notes

Verify the manufacturer status as Fairchild Semiconductor was acquired by ON Semiconductor in September 2016. Confirm that the component designation remains valid under the new corporate structure. Ensure the datasheet references align with current production standards. Check for any specific ordering suffixes that may indicate package variations or tape-and-reel specifications. Validate authenticity through authorized distribution channels.

Selection Notes

Select this component when a bidirectional bus switch with high-speed performance is required. The 8 x 1:1 configuration suits applications needing multiple independent signal paths. The wide supply voltage range allows compatibility with various logic families. Consider the 48-pin TSSOP package for surface-mount assembly constraints. Evaluate the ±24 mA drive strength against load requirements.

Part Context

This part belongs to the FSTU series of high-speed bus switches. It complements other devices like the FSTU32160, which offers different bit-width configurations. The series is designed for general-purpose signal switching in digital electronics. Fairchild Semiconductor established this line to address high-speed data transfer needs in consumer and industrial applications.
