Datasheet
The DS3690 is a 26-channel, three-stateable transmis-
sion gate designed for transparent digital signal trans-
fer when enabled and fast-gated bus isolation when the
device is disabled. Each of the 26 independent chan-
nels can be used for input, output, or I/O signal appli-
cations, with a typical signal propagation delay of less
than 10ns. Using the logic-control input, all channels
can be simultaneously enabled for bus transmission or
forced to a high-impedance condition to isolate a criti-
cal component on that bus.
The DS3690 operates on a single 3.3V (typical) power
supply and is available in a space-saving 56-pin lead-
free TQFN package.

... Figure 3). CEZ MICRO 6 _______________________________________________________________________________________ To achieve the best results when using the DS3690, decouple the power supply with a 0.1µF capacitor. Use a high-quality, ceramic surface-mount capacitor if possible. Surface-mount components minimize lead inductance, which improves performance, while ceram- ic capacitors have adequately high-frequency response for decoupling applications ...
