Description
Part of the CD4000 IC series, the CD4066 is a quad bilateral switch designed for the transmission or multiplexing of analog or digital signals. It maintains pin-for-pin compatibility with CD4016BC and directly interfaces with CMOS, NMOS, and TTL devices. The IC offers a broad working voltage range, providing versatility in various applications. Noteworthy features include squelch controlling and ESD barring.
Specifications:
- Wide supply voltage range: 3V to 15V
- High noise immunity: 0.45 VDD (typ.)
- Wide range of digital and ±7.5 VPEAK analog switching
- "ON" resistance for 15V operation: 80Ω
- Matched "ON" resistance ∆RON = 5Ω (typ.) over 15V signal input
- "ON" resistance flat over peak-to-peak signal range
- High "ON"/"OFF" output voltage ratio: 65 dB (typ.) @ 10 kHz, RL = 10 kΩ
- Extremely high control input impedance: 10^12Ω (typ.)
- Low crosstalk: -50 dB (typ.) between switches @ 0.9 MHz, RL = 1 kΩ
- Frequency response, switch "ON": 40 MHz (typ.)
