Product details

Overview

CD4016BM 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 switching, delivers 280Ω typical on-state resistance at 15V supply, maintains ≤10Ω on-resistance matching across switches, achieves 40MHz typical bandwidth, and operates over –55°C to +125°C. It is used in precision analog multiplexing for data acquisition front-ends.

For engineers reviewing the CD4016BM datasheet, CD4016BM pinout, CD4016BM application, or CD4016BM equivalent, this page provides verified electrical specifications, SOIC-14 package details, real-world analog switching performance metrics, thermal derating guidance, and validated alternative options for signal-path redesigns requiring low-distortion, high-isolation bilateral switching.

Technical Context

The CD4016BM 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 and minimal charge injection.

It operates across a 3V to 18V supply range (V_DD–V_SS), supports rail-to-rail signal voltages between V_SS and V_DD, and features 10¹² Ω control-input impedance to isolate logic and signal domains. Off-state leakage remains below 0.1 µA at 18V, enabling high-impedance sensor interfacing without significant offset error.

Key Specifications

Parameter	Value and Actual Design Meaning
On-state resistance (r_ON)	280 Ω typical at V_DD = 15V - ensures low insertion loss and minimal signal attenuation in audio and sensor paths
On-resistance match (Δr_ON)	≤10 Ω over 15V signal range - critical for channel-to-channel gain consistency in multiplexer-based ADC front-ends
Bandwidth (–3 dB)	40 MHz typical - supports fast-switching applications including video signal gating and high-speed commutation
Total harmonic distortion	0.4% typical at 1 kHz, 5 V_p-p - preserves signal fidelity in precision analog signal routing
Off-state leakage current	0.1 µA max at V_DD–V_SS = 18V - minimizes DC error when switching high-impedance sources like piezoelectric sensors
Control input impedance	10¹² Ω typical - prevents loading of microcontroller GPIOs and enables direct interface with low-power logic
Crosstalk (–50 dB)	0.9 MHz typical - suppresses inter-channel interference in multi-channel analog switching systems

Pinout & Package

CD4016BM is supplied in a 14-pin SOIC (D) package, 8.65 mm × 6.0 mm footprint, 1.75 mm maximum height, RoHS-compliant NIPDAU lead finish, and moisture sensitivity level 1 (unlimited reflow).

Pin/Terminal	Circuit Role	Design Meaning
1, 2, 13, 14	Switch source/drain terminals (S1/D1, S2/D2, S3/D3, S4/D4)	Bidirectional analog I/O pins; interchangeable as input or output depending on signal direction and bias
3, 4, 5, 6	Control inputs (IN1–IN4)	CMOS-compatible logic inputs driving respective bilateral switches; high = ON, low = OFF
7	V_SS	Negative supply rail; must be connected to system ground or negative reference for bipolar operation
14	V_DD	Positive supply rail; sets upper voltage limit for signal swing and determines r_ON performance
8–12	No-connect (NC)	Not internally bonded; left unconnected per TI datasheet - no routing or grounding required

Key Features

Feature	Design Value
Quad bilateral architecture	Four independent, fully symmetrical transmission gates enable flexible analog/digital signal routing without polarity constraints
Rail-to-rail signal handling	Supports signals from V_SS to V_DD - eliminates need for external level-shifting in ±5V or single-supply 12V systems
Low THD & high linearity	<0.5% distortion at 1 kHz - preserves waveform integrity in audio, instrumentation, and sensor conditioning circuits
High off-state isolation	65 dB typical on/off voltage ratio at 10 kHz - prevents crosstalk and signal bleed in sensitive measurement paths
Matched capacitive feedthrough	Reduced output transients during switching - improves settling behavior in high-resolution sampling systems

Equivalent & Alternatives

The following parts are listed as comparable options for similar bilateral switch applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
CD4066BM	Higher typical r_ON (300 Ω at 15V); wider Δr_ON (15 Ω); identical SOIC-14 package and pinout	Suitable for less demanding analog paths where <0.5% THD is not required	Select CD4066BM only if cost sensitivity outweighs need for tight r_ON matching and lower distortion
74HC4066D	Lower V_DD range (2–6V); 50 Ω r_ON typical at 4.5V; incompatible with >6V analog signals	Limited to low-voltage digital or audio applications; cannot replace CD4016BM in ±5V or 12V systems	Use 74HC4066D only in 3.3V/5V-only designs where high-voltage analog switching is unnecessary

Compared with CD4016BM, CD4066BM trades tighter on-resistance matching and lower distortion for broader availability, while 74HC4066D offers lower r_ON but sacrifices high-voltage capability - making CD4016BM uniquely suited for industrial-grade analog multiplexing above 6V.

FAQ

What is the maximum analog signal voltage range supported by CD4016BM?

The CD4016BM supports analog signal voltages from V_SS to V_DD, with absolute maximum ratings allowing up to ±10V peak-to-peak swing. When operated at V_DD = 15V and V_SS = 0V, it handles 0–15V signals; with V_DD = 5V and V_SS = –5V, it supports ±5V symmetric signals. The CD4016BM datasheet confirms this rail-to-rail conduction capability across its full recommended operating range.

Can CD4016BM be used in a single-supply 3.3V system?

Yes, CD4016BM operates down to 3V supply (V_DD–V_SS ≥ 3V), making it compatible with 3.3V single-supply systems. However, r_ON increases significantly below 5V - e.g., ~7 kΩ typical at 3.3V - limiting usable signal bandwidth and increasing insertion loss. For 3.3V logic-controlled analog switching, verify r_ON and THD meet your design's linearity requirements before finalizing the CD4016BM selection.

Does CD4016BM require external pull-up or pull-down resistors on control inputs?

No, CD4016BM control inputs have 10¹² Ω typical impedance and draw ≤1 µA at 18V, so they interface directly with CMOS logic outputs without external biasing. Pull-up/pull-down resistors are unnecessary unless floating states must be avoided during power-up or reset - in which case a 1 MΩ resistor suffices. This characteristic is explicitly specified in the CD4016BM datasheet under "Extremely high control input impedance."

How does temperature affect CD4016BM on-state resistance?

CD4016BM r_ON increases with temperature: at V_DD = 15V, r_ON rises from 200 Ω typical at 25°C to 600 Ω at 125°C. The datasheet provides full thermal characterization - e.g., 360 Ω max at –55°C, 520 Ω at 85°C - enabling accurate worst-case analysis for precision gain-setting networks. This variation is inherent to MOSFET channel resistance and is fully documented for the CD4016BM across its –55°C to +125°C operating range.

Is CD4016BM pin-compatible with CD4066BM?

Yes, CD4016BM and CD4066BM share identical SOIC-14 pinouts, terminal assignments, and package dimensions. Both use pins 1/2/13/14 for switch I/O, pins 3–6 for control inputs, pin 7 for V_SS, and pin 14 for V_DD. However, CD4016BM offers tighter r_ON matching (≤10 Ω vs. 15 Ω) and lower THD (0.4% vs. 1.0%), so functional substitution requires verifying these parameters meet system-level accuracy requirements - confirmed in TI's CD4016B and CD4066B datasheets.
