Analog Switches - Special Purpose Procurement Notes

Verify the specific ordering suffix to confirm the tape-and-reel quantity and packaging configuration. Ensure compliance with RoHS directives and REACH regulations before integration. Confirm availability status as manufacturing transitions may affect lead times. Validate that the component meets the required operating temperature range for the target environment.

Analog Switches - Special Purpose Selection Notes

Select this component when a low-profile SPDT switch is required for voltages up to 5.5 V. Consider the 4.5 Ω on-resistance for applications sensitive to insertion loss. Evaluate the 220 MHz bandwidth against the highest frequency signal in the design. Compare the SC-88 footprint against available PCB real estate constraints.
