The TMUX1248 is a general purpose 2:1, single-pole double-throw (SPDT), switch that supports a wide operating range of 1.08 V to 5.5 V. The device supports bidirectional analog and digital signals on the source (Sx) and drain (D) pins ranging from GND to VDD. The state of the select pin (SEL) controls which of the two sources pins are connected to the drain pin. Additionally, the TMUX1248 has a low supply current of 7 nA which enables the device to be used in a host of handheld or low power applications.
Break-before-make switching prevents both source pins from being enabled simultaneously. This feature adds robustness in the system by preventing source signals from shorting during switching events.
All logic inputs have 1.8 V logic compatible thresholds, allowing for operation with low voltage logic signals. Fail-Safe Logic circuitry allows voltages on the control pins to be applied before the supply pin, or at a higher voltage than the supply pin up to 5.5 V, protecting the device from potential damage.
