Product details
Overview
CD4016BF3A from Texas Instruments is a CMOS quad bilateral switch IC designed for analog and digital signal routing in high-voltage systems. It supports ±10V peak-to-peak analog signals or 20V digital switching, features 280Ω typical on-state resistance at 15V operation, matched on-resistance within 10Ω across its 15V input range, and delivers 40MHz typical bandwidth - enabling precision multiplexing in instrumentation front-ends and industrial control I/O modules.
For engineers reviewing the CD4016BF3A datasheet, CD4016BF3A pinout, CD4016BF3A application, or CD4016BF3A equivalent, this page provides verified specifications including on-resistance matching, THD & crosstalk performance, thermal metrics for hermetic ceramic DIP, and validated alternatives for analog switching in safety-critical or wide-temperature designs.
Technical Context
The CD4016BF3A implements four independent bilateral transmission gates, each controlled by a single logic-level input that simultaneously biases complementary p- and n-channel MOSFETs to achieve symmetrical conduction in both directions. Its architecture enables true bidirectional analog signal flow with minimal distortion and no polarity dependence.
Each switch exhibits extremely high off-state impedance (100pA leakage typ. at 18V), 10¹² Ω control-input impedance isolating logic from signal paths, and matched input/output capacitance (4pF typ.) to suppress transients. The device operates across –55°C to +125°C with supply voltage differential from 3V to 20V, supporting rail-to-rail analog signal handling up to VDD–VSS = 20V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-state resistance (rON) | 280Ω typical at VDD–VSS = 15V - ensures low insertion loss and minimal signal attenuation in analog paths |
| On-resistance matching | ≤10Ω max difference between any two switches at 15V - critical for channel-to-channel gain consistency in multiplexers |
| Bandwidth (switch on) | 40MHz typical - supports audio, ultrasonic, and medium-speed data acquisition without roll-off |
| Total harmonic distortion | <0.5% typ. at 1kHz, 5Vp-p, RL = 10kΩ - preserves signal fidelity in precision measurement circuits |
| Off-state leakage current | 100pA typical at VDD–VSS = 18V, TA = 25°C - minimizes offset error and DC drift in high-impedance sensor interfaces |
| Crosstalk (–50dB) | 0.9MHz typical - prevents interference between adjacent switched channels in multi-channel systems |
| Supply voltage range | 3V to 20V differential (VDD–VSS) - accommodates single-supply (3–20V) or dual-supply (±10V) configurations |
Pinout & Package
CD4016BF3A is supplied in a 14-lead hermetic ceramic dual-in-line package (CDIP, J suffix), with 19.15mm × 7.19mm body dimensions and 5.08mm max height. Pin 1 is marked by a notch or dot; leads are tin-lead (SNPB) finished.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 13, 14 | Signal terminals (S/D pairs) | Bidirectional analog/digital signal paths: pins 1–2, 3–4, 5–6, and 12–13 form four independent switch channels |
| 3, 4, 5, 12 | Control inputs (A/B/C/D) | CMOS-compatible logic inputs driving respective switches; high = ON, low = OFF |
| 6, 7 | Power supply (VDD, VSS) | VDD (pin 6) and VSS (pin 7) set operating voltage differential; supports asymmetric rails (e.g., +15V/0V or +5V/–5V) |
| 8, 9, 10, 11 | No-connect / unused | Not internally bonded - must be left unconnected or tied to VSS per TI layout guidance to minimize noise coupling |
Key Features
| Feature | Design Value |
|---|---|
| Bilateral signal conduction | True bidirectional analog path with identical rON and THD in either direction - eliminates polarity constraints in sensor or audio routing |
| Matched on-resistance | ΔrON ≤10Ω over full 15V signal range - enables accurate gain-matching in programmable-gain amplifiers and calibrated multiplexers |
| Ultra-low off-state leakage | 100pA typ. at 18V - maintains DC accuracy in high-Z medical electrode interfaces and piezoelectric sensor conditioning |
| High control-input impedance | 10¹² Ω typ. - isolates logic control circuitry from sensitive analog signal paths, preventing loading or injection errors |
| Low crosstalk | –50dB at 0.9MHz - ensures channel independence in 4-channel data loggers and multi-sensor telemetry systems |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar bilateral switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CD4066BE | Higher typical rON (300Ω at 15V), wider ΔrON (20Ω), lower bandwidth (30MHz), same CDIP-14 package and pinout | Less suitable for precision gain-matched multiplexing but adequate for general-purpose digital gating | Select CD4066BE only when cost sensitivity outweighs rON matching and bandwidth requirements |
| MAX4617CPD+ | Lower rON (60Ω typ.), faster tpd (15ns), but limited to 12V max supply and plastic SOIC-14 package | Not rated for –55°C or hermetic environments; unsuitable for aerospace or extended-temperature industrial use | Choose MAX4617CPD+ only for commercial-grade, high-speed, low-voltage (<12V) applications where ceramic reliability is not required |
Compared with CD4016BF3A, CD4066BE trades precision analog performance for broader legacy compatibility, while MAX4617CPD+ offers speed and low rON at the expense of temperature range, voltage rating, and hermetic packaging - making CD4016BF3A uniquely suited for high-integrity analog switching in harsh environments.

FAQ
What is the maximum signal voltage swing supported by CD4016BF3A?
The CD4016BF3A supports analog signal swings up to ±10V peak-to-peak or digital signals up to 20V, constrained by the absolute maximum VDD–VSS rating of 20V. Signal voltage at source/drain pins must remain within VSS–0.5V to VDD+0.5V per the datasheet's Absolute Maximum Ratings table. This allows direct interfacing with ±10V op-amp stages or 0–20V industrial sensors without level-shifting circuitry.
Does CD4016BF3A require external pull-up or pull-down resistors on control inputs?
No, CD4016BF3A control inputs have CMOS-compatible thresholds and exhibit ultra-low leakage (≤1µA max at 18V), eliminating the need for external biasing. The device specifies VILC ≤0.7V and VIHC ≥3.5V at VDD = 5V, ensuring reliable logic-level compatibility with standard microcontrollers and FPGAs without additional components.
How does the on-state resistance matching of CD4016BF3A impact multiplexer accuracy?
CD4016BF3A guarantees ≤10Ω on-resistance difference between any two switches over a 15V signal range. In a 4:1 analog multiplexer, this tight matching ensures channel-to-channel gain variation remains below 0.4% for a 2.5kΩ load, directly preserving measurement accuracy in calibrated data acquisition systems where relative channel error must be minimized.
Can CD4016BF3A operate with asymmetric supply rails such as +15V and 0V?
Yes, CD4016BF3A operates with any VDD–VSS differential from 3V to 20V, including asymmetric configurations like VDD = +15V and VSS = 0V. Signal voltages must stay within VSS–0.5V to VDD+0.5V, allowing full 0–15V analog signal routing. This flexibility simplifies integration into mixed-signal systems with disparate supply domains.
Is CD4016BF3A suitable for high-frequency RF switching applications?
No, CD4016BF3A is not designed for RF switching. Its 40MHz –3dB bandwidth applies to baseband analog signals, and its 0.9MHz –50dB crosstalk frequency indicates significant inter-channel coupling above audio frequencies. For RF applications above 1MHz, purpose-built RF switches with 50Ω impedance matching and GHz-range bandwidth should be used instead.
