SN74LVC1G3157, SPDT Analog Switches

Texas Instruments' SN74LVC1G3157, single-pole, double-throw (SPDT) analog switches are designed for 1.65 VCC to 5.5 VCC operations. The SN74LVC1G3157 devices can handle both analog and digital signals. The SN74LVC1G3157 devices permit signals with amplitudes of up to VCC (peak) to be transmitted in either direction.

Applications include signal gating, chopping, modulation or demodulation (modem), and signal multiplexing for analog-to-digital and digital-to-analog conversion systems.

  • 1.65 VCC to 5.5 VCC operation
  • Useful for both analog and digital applications
  • Specified break-before-make switching
  • Rail-to-rail signal handling
  • Operating frequency typically 340 MHz at room temperature
  • High degree of linearity
  • High speed, typically 0.5 ns (VCC = 3 V, CL = 50 pF)
  • Low ON-state resistance, typically ≠ 6 Ω (VCC = 4.5 V)
  • Latch-up performance exceeds 100 mA per JESD 78, Class II
  • ESD protection exceeds JESD 22
    • 2000 V human body model (A114-A)
    • 1000 V charged-device model (C101)
