GENERAL DESCRIPTION
The 74HC4066 and 74HCT4066 are high-speed Si-gate CMOS devices and are pin compatible with the HEF4066B. They are specified in compliance with JEDEC standard no. 7A. The 74HC4066 and 74HCT4066 have four independent analog switches. Each switch has two input/output pins (pins nY or nZ) and an active HIGH enable input pin (pin nE). When pin nE = LOW the belonging analog switch is turned off. The 74HC4066 and 74HCT4066 are pin compatible with the 74HC4016 and 74HCT4016 but exhibit a much lower on-resistance. In addition, the on-resistance is relatively
constant over the full input signal range.

FEATURES
• Very low ON-resistance:
   –50Ω(typical) at VCC= 4.5 V
   –45Ω(typical) at VCC= 6.0 V
   –35Ω(typical) at VCC= 9.0 V.
• Complies with JEDEC standard no. 7A
• ESD protection:
   HBM EIA/JESD22-A114-B exceeds 2000 V
   MM EIA/JESD22-A115-A exceeds 200 V.
• Specified from−40°C to +85°C and−40°C to +125°C.
