Quad bilateral switches

The 74LV4066 is a low-voltage Si-gate CMOS device that is pin and function compatible with the 74HC4066 and 74HCT4066.

The 74LV4066 has four independent switches. Each switch has two input/output pins (nY, nZ) and an active HIGH enable input pin (nE). When nE is LOW the corresponding analog switch is turned off.

The 74LV4066 has a ON-resistance which is reduced in comparison with the 74HCT4066.

Features and benefits

  • Optimized for low-voltage applications: 1.0 V to 3.6 V
  • Typical VOLP (output ground bounce): < 0.8 V at VCC = 3.3 V and Tamb = 25 °C
  • Accepts TTL input levels between VCC = 2.7 V and VCC = 3.6 V
  • Very low ON-resistance:
    • 60 Ω (typical) at VCC = 2.0 V
    • 35 Ω (typical) at VCC = 3.0 V
    • 25 Ω (typical) at VCC = 4.5 V
  • ESD protection:
    • HBM JESD22-A114F exceeds 2000 V
    • MM JESD22-A115-A exceeds 200 V
  • Specified from -40 °C to +80 °C and from -40 °C to +125 °C
