TS5A21366: Can I tie IN1 & IN2 together with single control signal along with other control circuit?

Part Number: TS5A21366

Hi TI experts,

For current project I'm evaluating using TS5A21366 to isolate the ADC signal from potentiometer to uController.

However I want to know if I can use only one control signal for IN1 & IN2.

Is this possible or is there any internal circuitry that I need to pay attention to?

Externally there is a pull down resistor 10K on the control signal for another PowerFET circuitry control.

Basically I wanted to use single signal to toggle the MOSFET and TS5A21366 if possible.

Hi Chieh Wei,

Using one control singal is fine if you don't need to control the 2 switches separately.

The control signal seen at the INx pins need to be within the range of recommended operating conditions, and the VIL and VIH(input logic low/high)pins are at the datasheet specified voltage level to control the ON/OFF signal.

Please see below snippets from TS5A21366 datasheet.

Thank you,

Helen
