STG5678

Low voltage dual SPDT switch

with negative rail capability

Flip-chip 12

Description

The STG5678 is a high-speed CMOS low voltage dual analog SPDT (single pole dual throw) switch or 2:1 multiplexer/de-multiplexer switch fabricated in silicon gate CMOS technology. It is designed to operate from 1.65 to 4.5 V.

The device is capable of handling signals with negative voltages from V any distortion.

- 5.5 V to VCC without

Additional key features are fast switching speed, break-before-make delay time and ultra low power consumption. All inputs and outputs are equipped with protection circuits against static discharge, giving them ESD immunity and transient excess voltage.

STG5678 Application hint

6 Application hint

6.1 Input signal dynamic range

The STG5678 negative analog switch allows input signals that fall below 0 V to pass through the switch without signal distortion. The input signal dynamic range VI consists of a positive-region and a negative-region.

The positive-region is limited by the level of V difference between V the operating range in the negative region.

For example, if V

Figure 13. Application diagram

and 5.5 V. The effect of this is that, the higher the VCC, the smaller

= 3.6 V, the input signal dynamic range is from -1.9 V to 3.6 V.
