3.3V 26-Channel, Three-Stateable
Transmission Gate
General Description
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
www.DataSheect4aUn.cobme 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.
