NOTES:

1. See test circuits and waveforms.

2. The bus switch contributes no Propagation Delay other than the RC Delay of the load interacting with the RC of the switch.

3.

|QCI| is the charge injection for a single switch DISCONNECT and applies to either single switches or multiplexers. |QDCI| is the charge injection for a multiplexer as

the multiplexed port switches from one path to another. Charge injection is reduced because the injection from the DISCONNECT of the first path is compensated by

the CONNECT of the second path.
