Product details
Overview
CD4016BPWR from Texas Instruments is a CMOS quad bilateral switch IC designed for analog and digital signal routing in mixed-signal systems. It supports ±10V peak-to-peak analog signals or 20V digital switching, features 280Ω typical on-state resistance at 15V operation, <0.5% THD at 1kHz, and operates across –55°C to +125°C. It is used in precision analog multiplexing, chopper-stabilized amplifiers, and digitally controlled gain/phase circuits.
For engineers reviewing the CD4016BPWR datasheet, CD4016BPWR pinout, CD4016BPWR application, or CD4016BPWR equivalent, this page delivers verified specifications, TSSOP-14 package details, real-world analog switching performance metrics, thermal behavior under load, and validated alternative options for signal-path design continuity.
Technical Context
The CD4016BPWR integrates four independent bilateral transmission gates, each controlled by a single logic-level input that simultaneously biases complementary p- and n-channel MOSFETs. Its symmetrical conduction path enables bidirectional analog signal flow with matched on-resistance (≤10Ω max mismatch over 15V range) and low feedthrough capacitance (0.2pF).
It operates from 3V to 18V supply differential (VDD–VSS), supports rail-to-rail signal voltages between VSS and VDD, and achieves 40MHz –3dB bandwidth in on-state with –50dB crosstalk suppression up to 0.9MHz - critical for high-fidelity multiplexed sensor or audio paths.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-state resistance (rON) | 280Ω typical at VDD = 15V, VSS = 0V - defines insertion loss and channel matching in precision analog routing |
| Signal voltage range | ±10V peak-to-peak or 0–20V unipolar - supports full-rail analog signal transmission without clipping |
| Total harmonic distortion | <0.5% typ. at 1kHz, 5Vp-p, RL = 10kΩ - ensures minimal nonlinear artifacts in audio and sensor conditioning |
| Off-state leakage current | 100pA typical at VDD–VSS = 18V - preserves DC accuracy and high-impedance node integrity |
| Bandwidth (on-state) | 40MHz typical - enables switching of fast analog waveforms including video sync and medium-speed data |
| Crosstalk (off-state) | –50dB typical at 0.9MHz - prevents coupling between adjacent channels in multi-channel acquisition systems |

| 3, 5, 12, 11 | Control inputs (A/B/C/D) | CMOS-compatible logic inputs enabling respective bilateral switches (active-high) |
| 7 | VSS | Negative supply or ground reference - sets lower signal rail and bias point |
| 14 | VDD | Positive supply - establishes upper signal rail and internal logic threshold |
| 6, 8, 9, 10 | Switch input/output (S/D) | Complementary S/D pairs for each of four switches - pin pairing follows standard CD4016 layout |
Key Features
| Feature | Design Value |

Equivalent & Alternatives
The following parts are listed as comparable options for similar bilateral switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CD4066BM96 | SOIC-14 package; 300Ω typical rON at 15V; identical pinout and logic interface | Higher thermal resistance (RθJA = 109.7°C/W vs. 120°C/W for PW); less suitable for high-density, thermally constrained PCBs | Preferred when SOIC footprint compatibility is required and board space permits larger package |
| 74HC4066PW | TSSOP-14; 50Ω typical rON at 4.5V but limited to 6V max VDD; higher drive strength, lower propagation delay | Not rated for ±10V analog signals - unsuitable for industrial or audio applications requiring extended voltage swing | Select only for low-voltage (≤5V) digital multiplexing where speed and low rON outweigh voltage range needs |
Compared with CD4016BPWR, CD4066BM96 offers identical functionality in SOIC with slightly higher thermal resistance, while 74HC4066PW trades voltage range for lower on-resistance and faster switching - making CD4016BPWR the sole choice for ±10V-capable, temperature-robust analog routing in compact layouts.

FAQ
What is the maximum signal voltage swing supported by CD4016BPWR?
The CD4016BPWR supports analog signal voltages from VSS to VDD, enabling ±10V peak-to-peak operation when powered with VDD = +10V and VSS = –10V. Its absolute maximum rating allows 20V differential, but signal excursion must remain within the supply rails to avoid damage or distortion. This makes CD4016BPWR suitable for industrial sensor interfaces and audio circuits requiring full-rail analog handling.
Does CD4016BPWR require external pull-up or pull-down resistors on its control inputs?
No, CD4016BPWR control inputs have extremely high impedance (1012Ω typical), so they do not require external biasing resistors. The inputs are CMOS-compatible and respond to standard logic levels: VIL ≤ 0.7V and VIH ≥ 3.5V at VDD = 5V. However, floating control pins must be avoided - always tie unused inputs to VDD or VSS to prevent unintended switching in CD4016BPWR.
How does temperature affect the on-state resistance of CD4016BPWR?
CD4016BPWR's on-state resistance increases with temperature: at VDD = 15V, rON is 200Ω typical at 25°C but rises to 600Ω at 125°C. This positive temperature coefficient is inherent to MOSFET conduction and must be accounted for in precision gain-setting or calibration-critical applications. For stable rON, operate CD4016BPWR below 85°C or include temperature compensation in system firmware.
Can CD4016BPWR be used in a single-supply configuration?
Yes, CD4016BPWR functions reliably in single-supply mode with VSS = 0V and VDD = 3V to 18V. Signal inputs must remain within 0V to VDD, and the device maintains 280Ω typical rON and <0.5% THD at 15V operation. This configuration is widely used in battery-powered data loggers and portable instrumentation where CD4016BPWR routes unipolar sensor outputs to shared ADCs.
What is the thermal resistance of CD4016BPWR in its TSSOP-14 package?
The CD4016BPWR in TSSOP-14 (PW) package has a junction-to-ambient thermal resistance (RθJA) of 120°C/W, measured under JEDEC JESD51-7 conditions. Its junction-to-board (RθJB) is 67.1°C/W, indicating effective heat transfer through soldered leads to the PCB copper. For continuous 10mA per switch operation, keep ambient temperature below 85°C to limit junction temperature to 125°C - a key design constraint for CD4016BPWR in sealed enclosures.
