| 5V, 1:1 (SPST), 4-CHANNEL PRECISION SWITCHES     DESCRIPTION  The UTC UMUX1111 is precision complementary metal-oxide  semiconductor (CMOS) device that has four independently  selectable single-pole / single-throw (SPST) switch. The device supports bidirectional analog and digital signals on the source (Sx)  and drain (Dx) pins ranging from GND to VDD.  Wide operating supply of 1.08V to 5.5V allows for use in a broad  array of applications from medical equipment to industrial systems.    FEATURES    * 1.8V Logic compatible  * Wide supply range: 1.08V ~ 5.5V  * Rail to rail operation  * Fail-safe logic  * Bidirectional signal path  * Break-before-make switching |
