Signal Switches, Multiplexers, Decoders Procurement Notes

Verify the specific ordering code CBT6800PW against the manufacturer's current production status, as legacy Philips Semiconductors products may have superseded documentation or availability changes. Confirm that the 24-Pin Plastic TSSOP package matches the mechanical constraints of the target design. Ensure the required operating temperature range of -40 to +85 °C aligns with the environmental specifications of the final assembly.

Signal Switches, Multiplexers, Decoders Selection Notes

Select this component when designing circuits that require low on-state resistance and fast switching speeds for 10-bit parallel buses. The device is suitable for applications needing TTL compatibility and specific precharge functionality to handle live insertion scenarios safely. Consider the 24-TSSOP package dimensions and the requirement for a separate BIASV pin for optimal performance in noise-sensitive environments.
