74HC1G66; 74HCT1G66

Single-pole single-throw analog switch

74HC1G66 and 74HCT1G66 are high-speed Si-gate CMOS devices. They are single-pole single-throw analog switches. The switch has two input/output pins (Y and Z) and an active HIGH enable input pin (E). When pin E is LOW, the analog switch is turned off.

The non-standard output currents are equal to those of the 74HC4066 and 74HCT4066.

Features

  • Wide supply voltage range from 2.0 V to 10.0 V for the 74HC1G66
  • 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 = 9.0 V
  • High noise immunity
  • Low power dissipation
  • Multiple package options
  • ESD protection:
    • HBM JESD22-A114E exceeds 2000 V
    • MM JESD22-A115-A exceeds 200 V
  • Specified from -40 Cel to +85 Cel and -40 Cel to +125 Cel
