The 74LVC1G3157GW from Nexperia is a single-pole double-throw (SPDT) analog switch in a compact TSSOP6 package. It provides low 6Ω typical on-resistance at 5V with 1.5Ω flatness, 300MHz bandwidth, and break-before-make switching for clean signal transitions. The wide 1.65V to 5.5V supply range and overvoltage-tolerant control inputs make it suitable for mixed-voltage systems. The 32mA continuous current rating and rail-to-rail signal handling support both analog and digital signal routing applications.

The 74LVC1G3157GW uses CMOS transmission gate topology to implement the SPDT switch function. A digital select input (S) controls which of the two throw terminals (Y0 or Y1) is connected to the common pole (Z). When S is low, Y0 is connected to Z; when S is high, Y1 is connected to Z. The break-before-make circuitry ensures the current path is briefly interrupted during switching, preventing momentary short circuits between the two input channels. The transmission gate structure provides bidirectional signal flow and rail-to-rail signal handling. The on-resistance is determined by the parallel combination of the PMOS and NMOS switch transistors, which are sized to minimize RON and its variation across the signal range.

Pin Name Type Function
1 Z I/O Common terminal (pole)
2 GND Power Ground
3 Y1 I/O Throw terminal 1 (selected when S=H)
4 Y0 I/O Throw terminal 0 (selected when S=L)
5 S Input Select control (overvoltage tolerant)
6 VCC Power Positive supply (1.65V to 5.5V)
  • ADC input channel multiplexing with low RON flatness
  • Audio signal routing between two sources and one output
  • Battery-powered sensor channel selection at 1.65V
  • 3.3V to 5V logic level signal multiplexing
  • Modulation/demodulation signal gating in communications
