TMUX1119DCKR

The TMUX1119 is a CMOS single-pole double-throw (2:1) switch. The wide supply voltage operating range of 1.08V to 5.5V supports a wide range of applications from medical devices to industrial systems. The device supports bidirectional analog and digital signals ranging from GND to VDD on the source (Sx) and drain (D) pins. All logic inputs have thresholds compatible with 1.8V logic levels, ensuring TTL and CMOS logic compatibility when the device operates within the valid supply voltage range. Failsafe logic circuitry allows voltage to be applied to the control pins before the supply pins, protecting the device from potential damage. The TMUX1119 is part of a family of precision switches and multiplexer devices. These devices feature very low on- and off-state leakage currents and low charge injection, making them suitable for stability in high-speed serial links in high-precision measurement applications. The low supply current of 3nA and compact package options make them suitable for thermal management optimization in portable applications, achieving high power density, high efficiency, and robustness.
