Active: In Production.

Description

The DS3690 is a 26-channel, three-stateable transmission gate designed for transparent digital signal transfer when enabled and fast-gated bus isolation when the device is disabled. Each of the 26 independent channels can be used for input, output, or I/O signal applications, 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 critical 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.
