74HC4066; 74HCT4066

Quad single-pole single-throw analog switch

The 74HC4066; 74HCT4066 is a quad single pole, single throw analog switch. Each switch features two input/output terminals (nY and nZ) and an active HIGH 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.

Features and benefits

  • Input levels nE inputs:

    • For 74HC4066: CMOS level

    • For 74HCT4066: TTL level

  • Low ON resistance:

    • 50 Ω (typical) at VCC = 4.5 V

    • 45 Ω (typical) at VCC = 6.0 V

    • 35 Ω (typical) at VCC = 9.0 V

  • Specified in compliance with JEDEC standard no. 7A

  • 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
