74LVC1G66 - Bilateral switch

General Description

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.

Key Features

  • 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.

74LVC1G66 Bilateral switch Rev. 12 — 12 January 2022 Product data sheet 1. General description 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. 2. 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.
