STG5678：Low voltage dual SPDT switch with negative rail capability

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_CC- 5.5 V to V_CCwithout any distortion.

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.

Key Features

• Distortion-free negative signal throughput down to VCC - 5.5 V
• Wide operating voltage range: VCC (opr) = 1.65 to 4.5 V single supply
• Ultra low power dissipation:ICC = 0.2 μ A (max.) at TA = 85 °C
• Low ON resistance:RON = 0.5 Ω (max. TA = 25 °C) at VCC = 3.6 V
• 4.3 V tolerant and 1.8 V compatible threshold on digital control input at VCC = 1.65 V to 4.5 V
• Latch-up performance exceeds 300 mA (JESD 17)
• ESD performance:
  • 2000-V human-body model (IEC61340-3-1:2002 level 2)
  • 200-V machine model (IEC61340-3-2 level M2)
  • 1000-V charge device model (JESD22-C101-A level III)
