74LVC1G66

Bilateral switch

The 74LVC1G66 is a single-pole, single-throw analog switch with two input/output terminals (nY and nZ) and a digital enable input (nE). When nE is LOW, the analog switch is turned off. Control 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 control 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

  • High noise immunity

  • CMOS low power consumption

  • TTL interface compatibility at 3.3 V

  • Overvoltage tolerant control inputs to 5.5 V

  • Latch-up performance meets requirements of JESD78 Class I

  • ESD protection:

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

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

  • Multiple package options

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