  • The STG5123 is a high speed CMOS low voltage single analog SPDT (single-pole double-throw) switch or 2:1 multiplexer/demultiplexer switch manufactured using silicon gate C2MOS technology. Designed to operate from a 1.65 to 4.5 V supply, this device is ideal for portable applications.

    The device offers very low ON-resistance (1 Ω) at VCC= 4.5 V. Switch S1 is ON (connected to common ports Dn) when the SEL input is held high, and OFF (state of high impedance exists between the two ports) when SEL is held low.
    Switch S2 is ON (connected to common port D) when the SEL input is held low, and OFF (state of high impedance exists between the two ports) when SEL is held high.
    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 to protect against static discharge, giving them immunity from ESD and transient excess voltage.

    Key Features

    • High speed:
      • tPD= 130 ps (typ.) at VCC= 3.0 V
      • tPD= 140 ps (typ.) at VCC= 2.3 V
    • Ultra low power dissipation:
      • ICC= 0.2 μA (max.) at TA= 85 °C
    • Low ON-resistance:
      • RON= 1.0 Ω (typ.) at VCC= 4.5 V
      • RON= 1.2 Ω (typ.) at VCC= 3.0 V
      • RON= 2.0 Ω (typ.) at VCC= 1.8 V
    • Wide operating voltage range:
      • VCC(opr.) = 1.65 to 4.5 V single supply
    • 5 V tolerant and 1.8 V compatible threshold ON digital control input at VCC= 1.65 to 4.5 V
    • Latch-up performance exceeds 200 mA per JESD 78, Class II
    • ESD performance tested per JESD 22
      • 2000 V human-body model (A114-B, Class II)
      • 200 V machine model (A115-A)
      • 1000 V charged-device model (C101)
