Product Overview
Motorola MC14016B is a CMOS quad bilateral analog switch designed to pass analog or digital signals under logic control. Each of the four independent switches uses complementary MOS devices in parallel, allowing bidirectional signal flow when enabled. When the control input is driven high, the corresponding switch closes; when driven low, it opens to a high-impedance state.
Operating from a 3.0 V to 18 V supply range, the MC14016B is suited for battery-powered systems, analog routing, and legacy telecom or audio circuits. As a B-series device, it provides improved noise immunity compared to earlier unbuffered variants.
Key Features
- Quad independent bilateral analog switches
- Supply voltage range: 3.0 Vdc to 18 Vdc (18 V absolute maximum)
- Bidirectional signal path on each switch
- Typical on-resistance: ~600 Ω at 10 V, ~300 Ω at 15 V
- Maximum switch current: ±25 mA
- Typical quiescent current: 0.005 µA at 5.0 Vdc
- Frequency handling up to 40 MHz (application dependent)
- DIP-14 through-hole package
- Control high = switch closed, control low = switch open
Applications
- Analog signal routing and multiplexing
- Audio signal switching in synthesizers and effects units
- Telecommunications signal gating
- Industrial process control boards
- Battery-powered maintenance or test circuits
- Sensor signal selection
- Legacy equipment repair specifying MC14016B
Frequently Asked Questions
Can this pass analog signals in both directions?
Yes. Each switch is bilateral, meaning the two signal pins are interchangeable and allow bidirectional current flow when enabled.
What happens if the signal exceeds the supply rails?
The signal must remain between VDD and VSS. Exceeding those limits can forward-bias internal protection structures and cause distortion or damage.
How does it compare to the MC14066B?
They are pin-compatible, but the MC14066B typically offers lower on-resistance. Substituting a 14016B in a circuit designed for a 14066B may introduce additional signal attenuation.
Are the control inputs tolerant of floating signals?
No. Control pins should not be left floating. They must be tied to a defined logic high or low level to prevent unstable operation.
Is ESD protection robust?
Older CMOS devices like this should be handled using standard antistatic precautions to prevent damage.
Four solid-state switches in one 14-pin package, built for the era when analog routing was done with CMOS transmission gates. If your board calls out MC14016B, this Motorola part keeps the signal path true to the original design.
