8 Detailed Description
8.1 Overview
The TS5A12301E device is a bidirectional, 1-channel, 1:2 mux, or single-pole double-throw (SPDT) analog switch. This switch offers low ON-state resistance and excellent THD performance, which makes it great for interfacing with an ADC.

8.3 Feature Description
8.3.1 Isolation
Isolation in power-down mode prevents current leakage through the device's signal path when VCC = 0 V. This allows signals to be present on the COM, NO, or NC pins before the device is powered up without damaging the device.
8.3.2 1.8-V Compatible Logic
The TS5A12301E supports 1.8-V logic irrespective to the supply voltage applied to the IC.
8.3.3 Integrated Control Input Pulldown
There is an integrated 6-MΩ pulldown resistor on the digital control input pin (IN) to keep the device in a known logic state during power up without needing an external component.
8.4 Device Functional Modes
