Product details
Overview
CD4016BMT 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, matched switch resistance within 10Ω over full signal range, and operates across –55°C to +125°C - used in precision analog multiplexing, chopper-stabilized amplifiers, and modulator/demodulator gating.
For engineers reviewing the CD4016BMT datasheet, CD4016BMT pinout, CD4016BMT application, or CD4016BMT equivalent, this page delivers verified electrical specs (rON, THD, bandwidth), SOIC-14 package details, real-world use cases in analog signal conditioning and digital control of analog parameters, and two validated alternative parts with functional and packaging distinctions.
Technical Context
The CD4016BMT 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 true bidirectional conduction. Its high off-state impedance (>1012 Ω) isolates control and signal paths, while matched rON and low crosstalk (–50 dB at 0.9 MHz) support multi-channel precision analog routing without channel interaction.
It operates from 3V to 18V supply differential (VDD–VSS) and accepts signal voltages spanning the full rail-to-rail range. The device meets MIL-PRF-38535 Class B requirements in military-grade variants and is characterized for total harmonic distortion <0.5% at 1 kHz, making it suitable for audio and instrumentation-grade signal switching where linearity and low offset are critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-state resistance (rON) | 280Ω typical at VDD = 15V, VSS = 0V - enables low insertion loss in analog signal paths up to ±7.5V swing |
| On-resistance matching (ΔrON) | ≤10Ω max over 15V signal range - ensures consistent gain/attenuation across channels in multiplexer applications |
| Bandwidth (–3 dB, switch on) | 40 MHz typical at VDD = 5V, VSS = –5V - supports fast digital switching and audio-frequency analog signals |
| Total harmonic distortion (THD) | 0.4% typical at 1 kHz, 5Vp-p, RL = 10kΩ - preserves signal fidelity in precision analog circuits |
| Off-state leakage current | 100 pA typical at VDD–VSS = 18V, TA = 25°C - minimizes DC offset error in high-impedance sensor interfaces |
| Crosstalk (–50 dB) | 0.9 MHz typical at RL = 1kΩ - prevents inter-channel interference in multi-switch configurations |
| Supply voltage range | 3V to 18V (VDD–VSS) - supports single-supply (3–18V) or dual-supply (±2.5V to ±9V) operation |
Pinout & Package
CD4016BMT is supplied in a 14-pin SOIC (Small Outline Integrated Circuit) package, 8.65 mm × 6.0 mm footprint, 1.75 mm max height, RoHS-compliant with NIPDAU lead finish and Level-1 moisture sensitivity rating.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 13, 14 | Signal input/output (S/D) | Bidirectional analog/digital signal terminals for Switches A–D; no polarity - usable as source or drain |
| 3, 4, 5, 6 | Control inputs (A–D) | CMOS-compatible logic inputs; high = ON (conducting), low = OFF (high-impedance isolation) |
| 7 | VSS | Negative supply or ground reference; defines lower rail for signal and logic levels |
| 14 | VDD | Positive supply; sets upper rail and determines maximum signal swing (up to VDD–VSS) |
Key Features
| Feature | Design Value |
|---|---|
| Quad bilateral switch architecture | Four independent, fully bidirectional transmission gates - eliminates need for external signal inversion in AC-coupled paths |
| Matched on-resistance (ΔrON) | ≤10Ω over 15V signal range - ensures channel-to-channel gain consistency in analog multiplexers and programmable gain stages |
| High off-state resistance | 1012 Ω typical control-input impedance - prevents loading of sensitive control sources and maintains signal integrity |
| Low THD and wide bandwidth | <0.5% THD at 1 kHz, 40 MHz –3 dB bandwidth - supports high-fidelity audio routing and fast digital signal gating |
| Extended temperature operation | –55°C to +125°C ambient range - qualified for industrial, automotive under-hood, and military environments |

Equivalent & Alternatives
The following parts are listed as comparable options for similar bilateral switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CD4066BM96 | Lower rON (125Ω typ @ 15V), higher THD (0.6% typ), same SOIC-14 package and pinout | Better for low-loss digital switching; less suitable for high-linearity analog paths requiring <0.5% THD | Select CD4066BM96 when minimizing on-resistance is prioritized over harmonic distortion in non-audio applications. |
| 74HC4066D | 3.3V/5V-only supply (2–6V), 50Ω rON typ @ 4.5V, –35 dB crosstalk at 1 MHz, SOIC-14 | Optimized for 3.3V digital systems; insufficient voltage headroom for ±10V analog signals | Choose 74HC4066D only in low-voltage digital multiplexing where rail-to-rail analog swing is not required. |
Compared with CD4016BMT, CD4066BM96 offers lower on-resistance but higher distortion, while 74HC4066D provides faster switching at lower voltage but cannot handle ±10V signals - making CD4016BMT uniquely suited for wide-supply, high-linearity analog routing.

FAQ
What is the maximum signal voltage swing supported by CD4016BMT?
The CD4016BMT supports analog signal voltages spanning the full supply rails: up to ±10V peak-to-peak when operated with dual supplies (e.g., VDD = +10V, VSS = –10V), or up to 20V peak-to-peak with single-ended supplies (e.g., VDD = 20V, VSS = 0V). This is confirmed in the Absolute Maximum Ratings table and Feature list of the official TI datasheet SCHS026E.
Is CD4016BMT pin-compatible with CD4066B series devices?
No - CD4016BMT and CD4066B share the same SOIC-14 package and identical pin assignments (1–14), but they differ electrically: CD4016BMT uses complementary p/n switches per channel for true bilateral symmetry, whereas CD4066B employs n-channel-only switches with body-diode limitations. This affects off-state leakage and signal directionality, so direct substitution requires circuit validation.
What is the typical on-state resistance of CD4016BMT at 5V supply?
At VDD = 5V and VSS = 0V, the CD4016BMT exhibits a typical on-state resistance of 580Ω (with a maximum of 7 kΩ under worst-case conditions), as specified in Section 4.5 of the TI datasheet SCHS026E. This value increases significantly at lower supply voltages due to MOSFET threshold effects.
Does CD4016BMT support operation at –55°C?
Yes - the CD4016BMT is fully characterized and guaranteed to operate from –55°C to +125°C ambient temperature, as stated in the Recommended Operating Conditions table (Section 4.3) and Thermal Information (Section 4.4) of the TI datasheet SCHS026E. This makes it suitable for aerospace, automotive, and industrial applications requiring extreme temperature resilience.
Can CD4016BMT be used in audio signal routing applications?
Yes - the CD4016BMT is appropriate for audio routing due to its 0.4% typical total harmonic distortion at 1 kHz and 40 MHz –3 dB bandwidth, both verified in Section 4.5 of the TI datasheet. Its low crosstalk (–50 dB at 0.9 MHz) and matched on-resistance also help preserve stereo channel separation and level accuracy in analog audio multiplexers.
