8 Detailed Description

8.1 Overview

The SN74LVC1G3157 device is a single-pole double-throw (SPDT) analog switch designed for 1.65-V to 5.5-V
VCC operation. The SN74LVC1G3157 device can handle analog and digital signals. The device permits signals with amplitudes of up to VCC (peak) to be transmitted in either direction.

8.3 Feature Description

The 1.65-V to 5.5-V supply operation allows the device to function in many different systems comprised of different logic levels, allowing rail-to-rail signal switching. Either the B1 channel or the B2 channel is activated depending upon the control input. If the control input is low, B1 channel is selected. If the control input is high, B2 channel is selected.

8.4 Device Functional Modes

Table 1 lists the ON channel when one of the control inputs is selected.
