74LVC2G66

Bilateral switch

The 74LVC2G66 is a dual single pole, single-throw analog switch. Each switch has two input/output terminals (nY and nZ) and a digital enable input (nE). When nE is LOW, the analog switch is turned off. Inputs can be driven from either 3.3 V or 5 V devices. This feature allows the use of these devices as translators in mixed 3.3 V and 5 V environments.

Schmitt-trigger action at all inputs makes the circuit tolerant of slower input rise and fall times.

Features and benefits

  • Wide supply voltage range from 1.65 V to 5.5 V
  • Very low ON resistance:
    • 7.5 Ω (typical) at VCC = 2.7 V
    • 6.5 Ω (typical) at VCC = 3.3 V
    • 6 Ω (typical) at VCC = 5 V
  • Switch current capability of 32 mA
  • Overvoltage tolerant inputs to 5.5 V
  • High noise immunity
  • CMOS low power consumption
  • TTL interface compatibility at 3.3 V
  • IOFF circuitry provides partial Power-down mode operation
  • Latch-up performance meets requirements of JESD78 Class I
  • Complies with JEDEC standards:
    • JESD8-7 (1.65 V to 1.95 V)
    • JESD8-5 (2.3 V to 2.7 V)
    • JESD8C (2.7 V to 3.6 V)
    • JESD36 (4.5 V to 5.5 V)
  • ESD protection:
    • HBM JESD22-A114F exceeds 2000 V
    • MM JESD22-A115-A exceeds 200 V
  • Multiple package options
  • Specified from -40 °C to +85 °C and -40 °C to +125 °C
