Overvoltage tolerant bilateral switch

The 74LVCV2G66 is a low-power, low-voltage, high-speed Si-gate CMOS device.

The 74LVCV2G66 provides two single pole single throw analog or digital switches. Each switch includes an overvoltage tolerant input/output terminal (pin nZ), an output/input terminal (pin nY) and low-power active HIGH enable input (pin nE).

The overvoltage tolerant switch terminals allow the switching of signals in excess of VCC. The low-power enable input eliminates the necessity of using current limiting resistors in portable applications when using control logic signals much lower than VCC. These inputs are also overvoltage tolerant.

Features and benefits

  • Wide supply voltage range from 2.3 V to 5.5 V

  • Ultra low-power operation

  • Very low ON resistance:

    • 8.0 Ω (typical) at VCC = 2.7 V

    • 7.5 Ω (typical) at VCC = 3.3 V

    • 7.3 Ω (typical) at VCC = 5.0 V.

  • 5 V tolerant input for interfacing with 5 V logic

  • High noise immunity

  • Switch handling capability of 32 mA

  • CMOS low-power consumption

  • Latch-up performance exceeds 250 mA

  • Incorporates overvoltage tolerant analog switch technology

  • Switch accepts voltages up to 5.5 V independent of VCC

  • ESD protection:

    • HBM: ANSI/ESDA/JEDEC JS-001 class 2 exceeds 2000 V

    • CDM: ANSI/ESDA/JEDEC JS-002 class C3 exceeds 1000 V

  • Specified from -40 °C to +85 °C and -40 °C to +125 °C
