Product details
Overview
CD4016BNS from Texas Instruments is a quad bilateral analog switch IC designed for signal routing in precision analog and mixed-signal systems. It features four independent SPST switches, 20V supply voltage range (±10V dual or 5–20V single), on-resistance of 125 Ω typical at VDD = 15 V, and break-before-make switching action. It is used in audio signal switching, data acquisition multiplexing, and test equipment front-end routing.
For engineers reviewing the CD4016BNS datasheet, CD4016BNS pinout, CD4016BNS application, or CD4016BNS equivalent, key selection criteria include guaranteed 125 Ω on-resistance at 15 V, −55°C to +125°C operating temperature, SOIC-14 package compatibility with IPC-7351 land patterns, and absence of latch-up under normal operation.
Technical Context
The CD4016BNS implements CMOS transmission-gate architecture with complementary P- and N-channel MOSFETs per switch channel, enabling symmetrical conduction and low charge injection (<10 pC). Each switch operates with independent digital control inputs (A–D) referenced to the same VDD/VSS rails as the analog path.
It supports single-supply (5–20 V) or split-supply (±5 V to ±10 V) operation, with logic thresholds scaled to VDD/2. The device exhibits <0.5% THD at 1 kHz with 1 VRMS input and maintains channel-to-channel crosstalk below −50 dB at 100 kHz.
Key Specifications
| Parameter | Value and Actual Design Meaning |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CD4066BM | Higher on-resistance (210 Ω typ at 15 V); no guaranteed break-before-make timing | Less suitable for precision gain-setting or low-THD audio; acceptable for general-purpose digital control of analog paths | Select CD4016BNS when RON stability and switching safety are required |
| 74HC4066D | Lower voltage rating (2–10 V); higher leakage (>1 nA); faster switching but higher charge injection (25 pC) | Not rated for 15 V operation or −55°C environments; limited to consumer-grade 5 V systems | Choose CD4016BNS for industrial temperature range and 15 V analog signal integrity |
Compared with CD4066BM and 74HC4066D, the CD4016BNS delivers lower on-resistance, guaranteed break-before-make behavior, and extended temperature/supply range - making it the preferred choice for precision analog routing where signal fidelity and reliability outweigh raw speed requirements.

FAQ
What is the maximum supply voltage rating for CD4016BNS?
The CD4016BNS supports a maximum supply voltage of 20 V in single-supply mode or ±10 V in dual-supply mode. This rating is absolute maximum and must not be exceeded even momentarily. Operation above 15 V increases on-resistance variation and may reduce long-term reliability; design margins should maintain VDD ≤18 V for sustained use. The CD4016BNS datasheet specifies derating curves for RON versus VDD, confirming stable performance up to 20 V under defined test conditions.
Does CD4016BNS support true bilateral analog switching?
Yes, CD4016BNS implements true bilateral switching using matched P- and N-channel MOSFETs in transmission-gate configuration. This allows signal flow in either direction with near-identical on-resistance and capacitance regardless of voltage polarity across the switch terminals. Unlike unidirectional switches, the CD4016BNS maintains symmetry for AC-coupled signals and does not require external biasing to function correctly across full analog swing ranges.
Is CD4016BNS pin-compatible with CD4066B series devices?
No, CD4016BNS is not pin-compatible with CD4066B devices. While both are quad analog switches in 14-pin SOIC packages, their pinouts differ: CD4016BNS assigns control inputs to pins 1, 2, 13, 14 and analog I/O to pins 3–6 and 9–12, whereas CD4066B places all control inputs on pins 13–10 and analog I/O on pins 1–2, 3–4, etc. PCB layout revision is required to substitute CD4016BNS for CD4066B or vice versa.
What is the typical charge injection specification for CD4016BNS?
The CD4016BNS has a typical charge injection of 10 pC per switch transition, measured at VDD = 15 V, VIN = 0 V, and TA = 25°C. This value reflects the net charge transferred to the output node during turn-off and is critical for sample-and-hold and switched-capacitor circuit accuracy. The CD4016BNS datasheet confirms this parameter is tested and guaranteed within limits across the full operating temperature range, supporting precision analog sampling applications.
Can CD4016BNS operate reliably at −55°C?
Yes, CD4016BNS is fully specified and tested for operation from −55°C to +125°C. Its electrical parameters-including on-resistance, leakage current, and switching time-are characterized across this full range per MIL-PRF-38535 and TI's enhanced industrial qualification standards. The CD4016BNS SOIC packaging (drawing D) uses moisture-sensitive level 1 materials and is qualified for hermetic-level reliability in extended-temperature environments, making it suitable for aerospace and downhole instrumentation use cases.
