74AHCT1G66 - Single-pole single-throw analog switch

Download the 74AHCT1G66 datasheet PDF. This datasheet also covers the 74AHC1G66 variant, as both devices belong to the same single-pole single-throw analog switch family and are provided as variant models within a single manufacturer datasheet.

General Description

The 74AHC1G66; 74AHCT1G66 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.

The enable input is overvoltage tolerant.

Key Features

  • Very low ON resistance:.
  • 26 Ω (typ. ) at VCC = 3.0 V.
  • 16 Ω (typ. ) at VCC = 4.5 V.
  • 14 Ω (typ. ) at VCC = 5.5 V.
  • Wide supply voltage range from 2.0 to 5.5 V.
  • Overvoltage tolerant control input to 5.5 V.
  • High noise immunity.
  • CMOS low power dissipation.
  • Latch-up performance exceeds 100 mA per JESD 78 Class II Level A.
  • SOT353-1 and SOT753 package options.
  • ESD protection:.
  • HBM JESD22-A114E: excee.

74AHC1G66; 74AHCT1G66 Single-pole single-throw analog switch Rev. 5 — 11 January 2022 Product data sheet 1. General description The 74AHC1G66; 74AHCT1G66 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. The enable input is overvoltage tolerant. This feature allows the use of these devices as translators in mixed voltage environments. 2.
