74HCT1G66 - Single-pole single-throw analog switch

Download the 74HCT1G66 datasheet PDF. This datasheet also covers the 74HC1G66 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.

Description

The 74HC1G66; 74HCT1G66 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.

Inputs include clamp diodes.

Features

74HC1G66; 74HCT1G66 Single-pole single-throw analog switch Rev. 5 — 27 January 2022 Product data sheet 1. General description The 74HC1G66; 74HCT1G66 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. Inputs include clamp diodes. This enables the use of current limiting resistors to interface inputs to voltages in excess of VCC. The HCT device features control inputs with reduced input threshold levels to allow interfacing to TTL logic levels. 2. Features and benefits • Wide supply voltage range from 2.0 V to 10.0 V • Very low ON resistance: • 45 Ω (typ.) at VCC = 4.5 V • 30 Ω (typ.) at VCC = 6.0 V • 25 Ω (typ.) at VCC = 9.
