Working Principle

The TS5A4597DCKRG4 is a dual 4-channel SPDT switch powered by a low voltage (1.8 V up to 5 V) supply. The switch has both signal and logic control inputs. The signal inputs are buffered for maximum signal integrity.

The logic control input is compatible with all common logic levels, including TTL, CMOS, LVCMOS, and LVTTL. The switch can be controlled via an external digital controller by changing register settings via the integrated EEPROM. This allows for fine control of the switch.

The switch has a 3 mA maximum quiescent current, making it suitable for applications with low power requirements. It also has an excellent isolation performance, which contributes to its superior signal integrity.
