The 74HC/HCT4066 are high-speed Si-gate CMOS devices and are pin compatible with the “4066” of the “4000B” series. They are specified in compliance with JEDEC standard no. 7A.
The Philips 74HC/HCT4066 are high-speed Si-gate CMOS devices containing four independent analog switches. Each switch has two input/output terminals and an active HIGH enable input, allowing signal transmission in either direction when enabled.
These devices exhibit very low ON-resistance (typically 50 Ω at Vcc = 4.5 V) which remains relatively constant over the full input signal range. They are pin compatible with the '4066' of the '4000B' series and comply with JEDEC standard no. 7A.
| Number of independent analog switches | Four |
|---|---|
| Typical ON-resistance at Vcc = 4.5 V | 50 Ω |
| Typical ON-resistance at Vcc = 6.0 V | 45 Ω |
| Typical ON-resistance at Vcc = 9.0 V | 35 Ω |
| Supply voltage range (74HCT) | 4.5 to 5.5 V |
Yes, they are pin compatible with the '4066' of the '4000B' series.
The typical ON-resistance is 50 Ω at 4.5 V.
