3.3V 26-Channel, Three-Stateable

Transmission Gate

_______________________________________________________________________________________ 3

Note 1: All voltages referenced to ground.

Note 2: Typical waveform shown is labeled CHxxA (input) to CHxxB (output), and is identical in function when selecting pin CHxxB

(as the input) to pin CHxxA (as the output).

Note 3: Output reference level is V

/2.

Note 4: Input transitions prior to the CE falling edge are ignored (don’t care).

Note 5: Propagation delay differential between any two channels when using a common input signal source.

Note 6: Guaranteed by design and not 100% tested.
